 # CherryPick Workspace
 
-Welcome to the CherryPick Workspace, a comprehensive suite for dependency management in Flutter applications. It consists of the `cherrypick` and `cherrypick_flutter` packages, designed to enhance modularity and testability by providing robust dependency and state management tools.
+CherryPick Workspace is a modular, open-source dependency injection ecosystem for Dart and Flutter, designed to offer lightweight, flexible, and scalable DI suitable for both backend and frontend (Flutter) development. This monorepo contains the main DI runtime library, annotation helpers, code generation for modular bindings, and seamless Flutter integration.
 
-## Overview
+---
 
-- **`cherrypick`**: A Dart library offering core tools for dependency injection and management through modules and scopes.
+## Packages Overview
-- **`cherrypick_flutter`**: A Flutter-specific library facilitating access to the root scope via the context using `CherryPickProvider`, simplifying state management within the widget tree.
 
-## Repository Structure
+- **[`cherrypick`](./cherrypick)**  
+  The core dependency injection library. Supports modular bindings, hierarchical scopes, named and singleton bindings, provider functions (sync/async), runtime parameters, and test-friendly composition.  
+  _Intended for use in pure Dart and Flutter projects._
 
-- **Packages**:
+- **[`cherrypick_annotations`](./cherrypick_annotations)**  
-  - `cherrypick`: Core DI functionalities.
+  A set of Dart annotations (`@module`, `@singleton`, `@instance`, `@provide`, `@named`, `@params`) enabling concise, declarative DI modules and providers, primarily for use with code generation tools.
-  - `cherrypick_flutter`: Flutter integration for context-based root scope access.
 
-## Quick Start Guide
+- **[`cherrypick_generator`](./cherrypick_generator)**  
+  A [source_gen](https://pub.dev/packages/source_gen)-based code generator that automatically converts your annotated modules and providers into ready-to-use boilerplate for registration and resolution within your app.  
+  _Reduces manual wiring and errors; compatible with build_runner._
 
-### Installation
+- **[`cherrypick_flutter`](./cherrypick_flutter)**  
+  Adds Flutter-native integration, exposing DI scopes and modules to the widget tree through `CherryPickProvider` and enabling dependency management throughout your Flutter app.
 
-To add the packages to your project, include the dependencies in your `pubspec.yaml`:
+---
+
+## Why CherryPick?
+
+- **Zero-overhead and intuitive API:**  
+  Clean, minimal syntax, strong typing, powerful binding lifecycle control.
+- **High testability:**  
+  Supports overriding and hierarchical scope trees.
+- **Both Sync & Async support:**  
+  Register and resolve async providers, factories, and dependencies.
+- **Seamless code generation:**  
+  Effortless setup with annotations + generator—skip boilerplate!
+- **Works with or without Flutter.**
+- **Production ready:**  
+  Robust enough for apps, packages, and server-side Dart.
+- **Extensible & Modular:**  
+  Add bindings at runtime, use sub-modules, or integrate via codegen.
+
+---
+
+## Get Started
+
+### 1. Add dependencies
+
+In your `pubspec.yaml`:
 
 ```yaml
 dependencies:
-  cherrypick: any
+  cherrypick: ^<latest-version>
-  cherrypick_flutter: any
+  cherrypick_annotations: ^<latest-version>
+
+dev_dependencies:
+  build_runner: ^<latest>
+  cherrypick_generator: ^<latest-version>
 ```
 
-Run `flutter pub get` to install the dependencies.
+For Flutter projects, add:
 
-### Usage
+```yaml
+dependencies:
+  cherrypick_flutter: ^<latest-version>
+```
 
-#### cherrypick
+### 2. Write a DI Module (with annotations)
 
-- **Binding Dependencies**: Use `Binding` to set up dependencies.
+```dart
+import 'package:cherrypick_annotations/cherrypick_annotations.dart';
+import 'package:cherrypick/cherrypick.dart';
 
-  ```dart
+@module()
-  Binding<String>().toInstance("hello world");
+abstract class MyModule extends Module {
-  Binding<String>().toProvide(() => "hello world").singleton();
+  @singleton()
-  ```
+  ApiClient apiClient() => ApiClient();
 
-- **Creating Modules**: Define dependencies within a module.
+  @provide()
+  DataRepository dataRepo(ApiClient client) => DataRepository(client);
 
-  ```dart
+  @provide()
-  class AppModule extends Module {
+  String greeting(@params() String name) => 'Hello, $name!';
-    @override
+}
-    void builder(Scope currentScope) {
+```
-      bind<ApiClient>().toInstance(ApiClientMock());
-    }
-  }
-  ```
 
-- **Managing Scopes**: Control dependency lifecycles with scopes.
+### 3. Generate the bindings
 
-  ```dart
+```sh
-  final rootScope = Cherrypick.openRootScope();
+dart run build_runner build
-  rootScope.installModules([AppModule()]);
+# or for Flutter:
-  final apiClient = rootScope.resolve<ApiClient>();
+flutter pub run build_runner build
-  ```
+```
 
-#### cherrypick_flutter
+The generator will create a `$MyModule` class with binding code.
 
-- **CherryPickProvider**: Wrap your widget tree to access the root scope via context.
+### 4. Install and Resolve
 
-  ```dart
+```dart
-  void main() {
+final scope = CherryPick.openRootScope()
-    runApp(CherryPickProvider(
+  ..installModules([$MyModule()]);
-      rootScope: yourRootScopeInstance,
-      child: MyApp(),
-    ));
-  }
-  ```
 
-- **Accessing Root Scope**: Use `CherryPickProvider.of(context).rootScope` to interact with the root scope in your widgets.
+final repo = scope.resolve<DataRepository>();
+final greeting = scope.resolve<String>(params: 'John'); // 'Hello, John!'
+```
 
-  ```dart
+_For Flutter, wrap your app with `CherryPickProvider` for DI scopes in the widget tree:_
-  final rootScope = CherryPickProvider.of(context).rootScope;
-  ```
 
-### Example Project
+```dart
+void main() {
+  runApp(
+    CherryPickProvider(child: MyApp()),
+  );
+}
+```

-# CherryPick Flutter
+# CherryPick
 
-`cherrypick_flutter` is a powerful Flutter library for managing and accessing dependencies within your application through a root scope context using `CherryPickProvider`. It offers simplified dependency injection, making your application more modular and test-friendly.
+`cherrypick` is a flexible and lightweight dependency injection library for Dart and Flutter. It provides an easy-to-use system for registering, scoping, and resolving dependencies using modular bindings and hierarchical scopes. The design enables cleaner architecture, testability, and modular code in your applications.
 
-## Quick Start
+## Key Concepts
 
-### Main Components in Dependency Injection (DI)
+### Binding
 
-#### Binding
+A **Binding** acts as a configuration for how to create or provide a particular dependency. Bindings support:
 
-A Binding is a custom instance configurator, essential for setting up dependencies. It offers the following key methods:
 
-- `toInstance()`: Directly provides an initialized instance.
+- Direct instance assignment (`toInstance()`, `toInstanceAsync()`)
-- `toProvide()`: Accepts a provider function or constructor for lazy initialization.
+- Lazy providers (sync/async functions)
-- `withName()`: Assigns a name to an instance, allowing for retrieval by name.
+- Provider functions supporting dynamic parameters
-- `singleton()`: Marks the instance as a singleton, ensuring only one instance exists in the scope.
+- Named instances for resolving by string key
+- Optional singleton lifecycle
 
-##### Example:
+#### Example
 
 ```dart
-// Direct instance initialization with toInstance()
+// Provide a direct instance
-Binding<String>().toInstance("hello world");
+Binding<String>().toInstance("Hello world");
 
-// Or use a provider for lazy initialization
+// Provide an async direct instance
-Binding<String>().toProvide(() => "hello world");
+Binding<String>().toInstanceAsync(Future.value("Hello world"));
 
-// Named instance
+// Provide a lazy sync instance using a factory
-Binding<String>().withName("my_string").toInstance("hello world");
+Binding<String>().toProvide(() => "Hello world");
 
-// Singleton instance
+// Provide a lazy async instance using a factory
-Binding<String>().toProvide(() => "hello world").singleton();
+Binding<String>().toProvideAsync(() async => "Hello async world");
+
+// Provide an instance with dynamic parameters (sync)
+Binding<String>().toProvideWithParams((params) => "Hello $params");
+
+// Provide an instance with dynamic parameters (async)
+Binding<String>().toProvideAsyncWithParams((params) async => "Hello $params");
+
+// Named instance for retrieval by name
+Binding<String>().toProvide(() => "Hello world").withName("my_string");
+
+// Mark as singleton (only one instance within the scope)
+Binding<String>().toProvide(() => "Hello world").singleton();
 ```
 
-#### Module
+### Module
 
-A Module encapsulates bindings, allowing you to organize dependencies logically. To create a custom module, implement the `void builder(Scope currentScope)` method.
+A **Module** is a logical collection point for bindings, designed for grouping and initializing related dependencies. Implement the `builder` method to define how dependencies should be bound within the scope.
 
-##### Example:
+#### Example
 
 ```dart
 class AppModule extends Module {
   @override
   void builder(Scope currentScope) {

-#### Scope
+### Scope
 
-A Scope is the container that manages your dependency tree, holding modules and instances. Use the scope to access dependencies with the `resolve<T>()` method.
+A **Scope** manages a tree of modules and dependency instances. Scopes can be nested into hierarchies (parent-child), supporting modular app composition and context-specific overrides.
 
-##### Example:
+You typically work with the root scope, but can also create named subscopes as needed.
+
+#### Example
 
 ```dart
-// Open the main scope
+// Open the main/root scope
-final rootScope = Cherrypick.openRootScope();
+final rootScope = CherryPick.openRootScope();
 
-// Install custom modules
+// Install a custom module
 rootScope.installModules([AppModule()]);
 
-// Resolve an instance
+// Resolve a dependency synchronously
 final str = rootScope.resolve<String>();
 
-// Close the main scope
+// Resolve a dependency asynchronously
-Cherrypick.closeRootScope();
+final result = await rootScope.resolveAsync<String>();
+
+// Close the root scope once done
+CherryPick.closeRootScope();
 ```
 
+#### Working with Subscopes
+
+```dart
+// Open a named child scope (e.g., for a feature/module)
+final subScope = rootScope.openSubScope('featureScope')
+  ..installModules([FeatureModule()]);
+
+// Resolve from subScope, with fallback to parents if missing
+final dataBloc = await subScope.resolveAsync<DataBloc>();
+```
+
+### Dependency Lookup API
+
+- `resolve<T>()` — Locates a dependency instance or throws if missing.
+- `resolveAsync<T>()` — Async variant for dependencies requiring async binding.
+- `tryResolve<T>()` — Returns `null` if not found (sync).
+- `tryResolveAsync<T>()` — Returns `null` async if not found.
+
+Supports:
+- Synchronous and asynchronous dependencies
+- Named dependencies
+- Provider functions with and without runtime parameters
+
 ## Example Application
 
-The following example demonstrates module setup, scope management, and dependency resolution.
+Below is a complete example illustrating modules, subscopes, async providers, and dependency resolution.

+# cherrypick_annotations
+
+[![License](https://img.shields.io/badge/license-Apache%202.0-blue.svg)](LICENSE)
+
+A lightweight set of Dart annotations for dependency injection (DI) frameworks and code generation, inspired by modern approaches like Dagger and Injectable. Optimized for use with [`cherrypick_generator`](https://pub.dev/packages/cherrypick_generator).
+
+---
+
+## Features
+
+- **@module** – Marks a class as a DI module for service/provider registration.
+- **@singleton** – Declares that a method or class should be provided as a singleton.
+- **@instance** – Marks a method or class so that a new instance is provided on each request.
+- **@provide** – Marks a method whose return value should be registered as a provider, supporting DI into its parameters.
+- **@named** – Assigns a string name to a binding for keyed resolution and injection.
+- **@params** – Indicates that a parameter should be injected with runtime-supplied arguments.
+- **@injectable** – Marks a class as eligible for automatic field injection. Fields annotated with `@inject` will be injected by the code generator.
+- **@inject** – Marks a field to be automatically injected by the code generator.
+- **@scope** – Declares the DI scope from which a dependency should be resolved for a field.
+
+These annotations streamline DI configuration and serve as markers for code generation tools such as [`cherrypick_generator`](https://pub.dev/packages/cherrypick_generator).
+
+---
+
+## Getting Started
+
+### 1. Add dependency
+
+```yaml
+dependencies:
+  cherrypick_annotations: ^latest
+```
+
+Add as a `dev_dependency` for code generation:
+
+```yaml
+dev_dependencies:
+  cherrypick_generator: ^latest
+  build_runner: ^latest
+```
+
+---
+
+### 2. Annotate your DI modules, providers, and injectable classes
+
+#### **Module and Provider Example**
+
+```dart
+import 'package:cherrypick_annotations/cherrypick_annotations.dart';
+
+@module()
+abstract class AppModule {
+  @singleton()
+  Dio dio() => Dio();
+
+  @named('baseUrl')
+  String baseUrl() => 'https://api.example.com';
+
+  @instance()
+  Foo foo() => Foo();
+
+  @provide()
+  Bar bar(Foo foo) => Bar(foo);
+
+  @provide()
+  String greet(@params() dynamic params) => 'Hello $params';
+}
+```
+
+With `cherrypick_generator`, code like the following will be generated:
+
+```dart
+final class $AppModule extends AppModule {
+  @override
+  void builder(Scope currentScope) {
+    bind<Dio>().toProvide(() => dio()).singleton();
+    bind<String>().toProvide(() => baseUrl()).withName('baseUrl');
+    bind<Foo>().toInstance(foo());
+    bind<Bar>().toProvide(() => bar(currentScope.resolve<Foo>()));
+    bind<String>().toProvideWithParams((args) => greet(args));
+  }
+}
+```
+
+---
+
+#### **Field Injection Example**
+
+```dart
+import 'package:cherrypick_annotations/cherrypick_annotations.dart';
+
+@injectable()
+class ProfileView with _$ProfileView{
+  @inject()
+  late final AuthService auth;
+
+  @inject()
+  @scope('profile')
+  late final ProfileManager manager;
+
+  @inject()
+  @named('admin')
+  late final UserService adminUserService;
+}
+```
+
+The code generator produces a mixin (simplified):
+
+```dart
+mixin _$ProfileView {
+  void _inject(ProfileView instance) {
+    instance.auth = CherryPick.openRootScope().resolve<AuthService>();
+    instance.manager = CherryPick.openScope(scopeName: 'profile').resolve<ProfileManager>();
+    instance.adminUserService = CherryPick.openRootScope().resolve<UserService>(named: 'admin');
+  }
+}
+```
+
+---
+
+## Annotation Reference
+
+### `@injectable`
+
+```dart
+@injectable()
+class MyWidget { ... }
+```
+Marks a class as injectable for CherryPick DI. The code generator will generate a mixin to perform automatic injection of fields marked with `@inject()`.
+
+---
+
+### `@inject`
+
+```dart
+@inject()
+late final SomeService service;
+```
+Applied to a field to request automatic injection of the dependency using the CherryPick DI framework.
+
+---
+
+### `@scope`
+
+```dart
+@inject()
+@scope('profile')
+late final ProfileManager manager;
+```
+Specifies the scope from which the dependency should be resolved for an injected field.
+
+---
+
+### `@module`
+
+```dart
+@module()
+abstract class AppModule {}
+```
+Use on classes to mark them as a DI module. This is the root for registering your dependency providers.
+
+---
+
+### `@singleton`
+
+```dart
+@singleton()
+Dio dio() => Dio();
+```
+Use on methods or classes to provide a singleton instance (the same instance is reused).
+
+---
+
+### `@instance`
+
+```dart
+@instance()
+Foo foo() => Foo();
+```
+Use on methods or classes to provide a new instance on each request (not a singleton).
+
+---
+
+### `@provide`
+
+```dart
+@provide()
+Bar bar(Foo foo) => Bar(foo);
+```
+Use on methods to indicate they provide a dependency to the DI module. Dependencies listed as parameters (e.g., `foo`) are resolved and injected.
+
+---
+
+### `@named`
+
+```dart
+@named('token')
+String token() => 'abc';
+```
+Assigns a name to a binding for keyed injection or resolution.  
+Can be used on both provider methods and fields.
+
+---
+
+### `@params`
+
+```dart
+@provide()
+String greet(@params() dynamic params) => 'Hello $params';
+```
+Indicates that this parameter should receive runtime-supplied arguments during dependency resolution.

 # CherryPick Flutter
 
-`cherrypick_flutter` is a Flutter library that allows access to the root scope through the context using `CherryPickProvider`. This package is designed to provide a simple and convenient way to interact with the root scope within the widget tree.
+`cherrypick_flutter` offers a Flutter integration to access and manage dependency injection scopes using the `CherryPickProvider`. This setup facilitates accessing the root scope directly from the widget tree, providing a straightforward mechanism for dependences management within Flutter applications.

 ```
 
+Note: The current implementation of `CherryPickProvider` does not directly pass a `rootScope`. Instead, it utilizes its methods to open root and sub-scopes internally.
+
 ### Accessing State
 
-To access the state provided by `CherryPickProvider`, use the `of` method. This is typically done in the `build` method of your widgets.
+Access the state provided by `CherryPickProvider` within widget `build` methods using the `of` method:
 
 ```dart
 class MyWidget extends StatelessWidget {
   @override

-    final rootScope = CherryPickProvider.of(context).rootScope;
+    final CherryPickProvider cherryPick = CherryPickProvider.of(context);

-    return Text('Current state: ${rootScope.someStateValue}');
+    // Use the rootScope or open a subScope as needed
+    final subScope = cherryPick.openSubScope(scopeName: "exampleScope");
+
+    return Text('Scope accessed!');
   }
 }
 ```
 
 ### Updating State

+# Cherrypick Generator
+
+**Cherrypick Generator** is a Dart code generation library for automating dependency injection (DI) boilerplate. It processes classes and fields annotated with [cherrypick_annotations](https://pub.dev/packages/cherrypick_annotations) and generates registration code for services, modules, and field injection for classes marked as `@injectable`. It supports advanced DI features such as scopes, named bindings, parameters, and asynchronous dependencies.
+
+---
+
+## Features
+
+- **Automatic Field Injection:**  
+  Detects classes annotated with `@injectable()`, and generates mixins to inject all fields annotated with `@inject()`, supporting scope and named qualifiers.
+
+- **Module and Service Registration:**  
+  For classes annotated with `@module()`, generates service registration code for methods using annotations such as `@provide`, `@instance`, `@singleton`, `@named`, and `@params`.
+
+- **Scope & Named Qualifier Support:**  
+  Supports advanced DI features:  
+    • Field-level scoping with `@scope('scopename')`  
+    • Named dependencies via `@named('value')`
+
+- **Synchronous & Asynchronous Support:**  
+  Handles both synchronous and asynchronous services (including `Future<T>`) for both field injection and module registration.
+
+- **Parameters and Runtime Arguments:**  
+  Recognizes and wires both injected dependencies and runtime parameters using `@params`.
+
+- **Error Handling:**  
+  Validates annotations at generation time. Provides helpful errors for incorrect usage (e.g., using `@injectable` on non-class elements).
+
+---
+
+## How It Works
+
+### 1. Annotate your code
+
+Use annotations from [cherrypick_annotations](https://pub.dev/packages/cherrypick_annotations):
+
+- `@injectable()` — on classes to enable field injection  
+- `@inject()` — on fields to specify they should be injected  
+- `@scope()`, `@named()` — on fields or parameters for advanced wiring  
+- `@module()` — on classes to mark as DI modules  
+- `@provide`, `@instance`, `@singleton`, `@params` — on methods and parameters for module-based DI
+
+### 2. Run the generator
+
+Use `build_runner` to process your code and generate `.module.cherrypick.g.dart` and `.inject.cherrypick.g.dart` files.
+
+### 3. Use the output in your application
+
+- For modules: Register DI providers using the generated `$YourModule` class.
+- For services: Enable field injection on classes using the generated mixin.
+
+---
+
+## Field Injection Example
+
+Given the following:
+
+```dart
+import 'package:cherrypick_annotations/cherrypick_annotations.dart';
+
+@injectable()
+class MyWidget with _$MyWidget {
+  @inject()
+  late final AuthService auth;
+
+  @inject()
+  @scope('profile')
+  late final ProfileManager manager;
+
+  @inject()
+  @named('special')
+  late final ApiClient specialApi;
+}
+```
+
+**The generator will output (simplified):**
+```dart
+mixin _$MyWidget {
+  void _inject(MyWidget instance) {
+    instance.auth = CherryPick.openRootScope().resolve<AuthService>();
+    instance.manager = CherryPick.openScope(scopeName: 'profile').resolve<ProfileManager>();
+    instance.specialApi = CherryPick.openRootScope().resolve<ApiClient>(named: 'special');
+  }
+}
+```
+You can then mix this into your widget to enable automatic DI at runtime.
+
+---
+
+## Module Registration Example
+
+Given:
+
+```dart
+import 'package:cherrypick_annotations/cherrypick_annotations.dart';
+
+@module()
+class MyModule {
+  @singleton
+  @instance
+  AuthService provideAuth(Api api);
+
+  @provide
+  @named('logging')
+  Future<Logger> provideLogger(@params Map<String, dynamic> args);
+}
+```
+
+**The generator will output (simplified):**
+```dart
+final class $MyModule extends MyModule {
+  @override
+  void builder(Scope currentScope) {
+    bind<AuthService>()
+      .toInstance(provideAuth(currentScope.resolve<Api>()))
+      .singleton();
+
+    bind<Logger>()
+      .toProvideAsyncWithParams((args) => provideLogger(args))
+      .withName('logging');
+  }
+}
+```
+
+---
+
+## Key Points
+
+- **Rich Annotation Support:** 
+  Mix and match field, parameter, and method annotations for maximum flexibility.
+- **Scope and Named Resolution:**
+  Use `@scope('...')` and `@named('...')` to precisely control where and how dependencies are wired.
+- **Async/Synchronous:**  
+  The generator distinguishes between sync (`resolve<T>`) and async (`resolveAsync<T>`) dependencies.
+- **Automatic Mixins:**  
+  For classes with `@injectable()`, a mixin is generated that injects all relevant fields (using constructor or setter).
+- **Comprehensive Error Checking:**  
+  Misapplied annotations (e.g., `@injectable()` on non-class) produce clear build-time errors.
+
+---
+
+## Usage
+
+1. **Add dependencies**
+
+   ```yaml
+   dependencies:
+     cherrypick_annotations: ^latest
+
+   dev_dependencies:
+     cherrypick_generator: ^latest
+     build_runner: ^2.1.0
+   ```
+
+2. **Annotate your classes and modules as above**
+
+3. **Run the generator**
+
+   ```shell
+   dart run build_runner build
+   # or, if using Flutter:
+   flutter pub run build_runner build
+   ```
+
+4. **Use generated code**
+
+   - Import the generated `.inject.cherrypick.g.dart` or `.cherrypick.g.dart` files where needed
+
+---
+
+## Advanced Usage
+
+- **Combining Modules and Field Injection:**  
+  It's possible to mix both style of DI — modules for binding, and field injection for consuming services.
+- **Parameter and Named Injection:**  
+  Use `@named` on both provider and parameter for named registration and lookup; use `@params` to pass runtime arguments.
+- **Async Factories:**  
+  Methods returning Future<T> generate async bindings and async field resolution logic.
+
+---
+
+## Developer Notes
+
+- The generator relies on the Dart analyzer, `source_gen`, and `build` packages.
+- All classes and methods are parsed for annotations.
+- Improper annotation usage will result in generator errors.

+# DI Code Generation with Annotations (CherryPick)
+
+CherryPick enables smart, fully-automated dependency injection (DI) for Dart/Flutter via annotations and code generation.
+This eliminates boilerplate and guarantees correctness—just annotate, run the generator, and use!
+
+---
+
+## 1. How does it work?
+
+You annotate classes, fields, and modules using [cherrypick_annotations].  
+The [cherrypick_generator] processes these, generating code that registers your dependencies and wires up fields or modules.
+
+You then run:
+```sh
+dart run build_runner build --delete-conflicting-outputs
+```
+— and use the generated files in your app.
+
+---
+
+## 2. Supported Annotations
+
+| Annotation        | Where           | Purpose                                                  |
+|-------------------|-----------------|----------------------------------------------------------|
+| `@injectable()`   | class           | Enables auto field injection; mixin will be generated    |
+| `@inject()`       | field           | Field will be injected automatically                     |
+| `@scope()`        | field/param     | Use a named scope when resolving this dep                |
+| `@named()`        | field/param     | Bind/resolve a named interface implementation            |
+| `@module()`       | class           | Marks as a DI module (methods = providers)               |
+| `@provide`        | method          | Registers a type via this provider method                |
+| `@instance`       | method          | Registers a direct instance (like singleton/factory)     |
+| `@singleton`      | method/class    | The target is a singleton                                |
+| `@params`         | param           | Accepts runtime/constructor params for providers         |
+
+**You can combine annotations as needed for advanced use-cases.**
+
+---
+
+## 3. Practical Examples
+
+### A. Field Injection (recommended for widgets/classes)
+
+```dart
+import 'package:cherrypick_annotations/cherrypick_annotations.dart';
+
+@injectable()
+class MyWidget with _$MyWidget { // the generated mixin
+  @inject()
+  late final AuthService auth;
+
+  @inject()
+  @scope('profile')
+  late final ProfileManager profile;
+
+  @inject()
+  @named('special')
+  late final ApiClient specialApi;
+}
+```
+
+- After running build_runner, the mixin _$MyWidget is created.
+- Call `MyWidget().injectFields();` (method name may be `_inject` or similar) to populate the fields!
+
+### B. Module Binding (recommended for global app services)
+
+```dart
+@module()
+abstract class AppModule extends Module {
+  @singleton
+  AuthService provideAuth(Api api) => AuthService(api);
+
+  @provide
+  @named('logging')
+  Future<Logger> provideLogger(@params Map<String, dynamic> args) async => ...
+}
+```
+
+- Providers can return async(`Future<T>`) or sync.
+- `@singleton` = one instance per scope.
+
+---
+
+## 4. Using the Generated Code
+
+1. Add to your `pubspec.yaml`:
+
+   ```yaml
+   dependencies:
+     cherrypick: any
+     cherrypick_annotations: any
+
+   dev_dependencies:
+     cherrypick_generator: any
+     build_runner: any
+   ```
+
+2. Import generated files (e.g. `app_module.module.cherrypick.g.dart`, `your_class.inject.cherrypick.g.dart`).
+
+3. Register modules:
+
+   ```dart
+   final scope = openRootScope()
+     ..installModules([$AppModule()]);
+   ```
+
+4. For classes with auto-injected fields, mix in the generated mixin and call the injector:
+
+   ```dart
+   final widget = MyWidget();
+   widget.injectFields(); // or use the mixin's helper
+   ```
+
+5. All dependencies are now available and ready to use!
+
+---
+
+## 5. Advanced Features
+
+- **Named and Scoped dependencies:** use `@named`, `@scope` on fields/methods and in resolve().
+- **Async support:** Providers or injected fields can be Future<T> (resolveAsync).
+- **Runtime parameters:** Decorate a parameter with `@params`, and use `resolve<T>(params: ...)`.
+- **Combining strategies:** Mix field injection (`@injectable`) and module/provider (`@module` + methods) in one app.
+
+---
+
+## 6. Troubleshooting
+
+- Make sure all dependencies are annotated, imports are correct, and run `build_runner` on every code/DI change.
+- Errors in annotation usage (e.g. `@singleton` on non-class/method) will be shown at build time.
+- Use the `.g.dart` files directly—do not edit them by hand.

+# Генерация DI-кода через аннотации (CherryPick)
+
+CherryPick позволяет получить умный и полностью автоматизированный DI для Dart/Flutter на основе аннотаций и генерации кода.
+Это убирает boilerplate — просто ставьте аннотации, запускайте генератор и используйте результат!
+
+---
+
+## 1. Как это работает?
+
+Вы размечаете классы, поля и модули с помощью [cherrypick_annotations].  
+[cherrypick_generator] анализирует их и создаёт код для регистрации зависимостей и подстановки полей или модулей.
+
+Далее — запускайте:
+```sh
+dart run build_runner build --delete-conflicting-outputs
+```
+— и используйте сгенерированные файлы в проекте.
+
+---
+
+## 2. Поддерживаемые аннотации
+
+| Аннотация          | Где применить    | Значение                                                   |
+|--------------------|------------------|------------------------------------------------------------|
+| `@injectable()`    | класс            | Включает автоподстановку полей, генерируется mixin         |
+| `@inject()`        | поле             | Поле будет автоматически подставлено DI                    |
+| `@scope()`         | поле/параметр    | Использовать определённый scope при разрешении             |
+| `@named()`         | поле/параметр    | Именованный биндинг для интерфейсов/реализаций             |
+| `@module()`        | класс            | Класс как DI-модуль (методы — провайдеры)                  |
+| `@provide`         | метод            | Регистрирует тип через этот метод-провайдер                |
+| `@instance`        | метод            | Регистрирует как прямой инстанс (singleton/factory, как есть)|
+| `@singleton`       | метод/класс      | Синглтон (один экземпляр на scope)                         |
+| `@params`          | параметр         | Пробрасывает параметры рантайм/конструктора в DI           |
+
+Миксуйте аннотации для сложных сценариев!
+
+---
+
+## 3. Примеры использования
+
+### A. Field Injection (рекомендуется для виджетов/классов)
+
+```dart
+import 'package:cherrypick_annotations/cherrypick_annotations.dart';
+
+@injectable()
+class MyWidget with _$MyWidget {
+  @inject()
+  late final AuthService auth;
+
+  @inject()
+  @scope('profile')
+  late final ProfileManager profile;
+
+  @inject()
+  @named('special')
+  late final ApiClient specialApi;
+}
+```
+- После build_runner появится mixin _$MyWidget.
+- Вызовите `MyWidget().injectFields();` (или соответствующий метод из mixin), чтобы заполнить поля.
+
+### B. Binding через модуль (вариант для глобальных сервисов)
+
+```dart
+@module()
+abstract class AppModule extends Module {
+  @singleton
+  AuthService provideAuth(Api api) => AuthService(api);
+
+  @provide
+  @named('logging')
+  Future<Logger> provideLogger(@params Map<String, dynamic> args) async => ...
+}
+```
+- Методы-провайдеры поддерживают async (Future<T>) и singleton.
+
+---
+
+## 4. Использование сгенерированного кода
+
+1. В `pubspec.yaml`:
+
+   ```yaml
+   dependencies:
+     cherrypick: any
+     cherrypick_annotations: any
+
+   dev_dependencies:
+     cherrypick_generator: any
+     build_runner: any
+   ```
+
+2. Импортируйте сгенерированные файлы (`app_module.module.cherrypick.g.dart`, `your_class.inject.cherrypick.g.dart`).
+
+3. Регистрируйте модули так:
+
+   ```dart
+   final scope = openRootScope()
+     ..installModules([$AppModule()]);
+   ```
+
+4. Для классов с автоподстановкой полей (field injection): используйте mixin и вызовите injector:
+
+   ```dart
+   final widget = MyWidget();
+   widget.injectFields(); // или эквивалентный метод из mixin
+   ```
+
+5. Все зависимости готовы к использованию!
+
+---
+
+## 5. Расширенные возможности
+
+- **Именованные и scope-зависимости:** используйте `@named`, `@scope` в полях/методах/resolve.
+- **Async:** Провайдеры и поля могут быть Future<T> (resolveAsync).
+- **Параметры рантайм:** через `@params` прямо к провайдеру: `resolve<T>(params: ...)`.
+- **Комбинированная стратегия:** можно смешивать field injection и модульные провайдеры в одном проекте.
+
+---
+
+## 6. Советы и FAQ
+
+- Проверьте аннотации, пути import и запускайте build_runner после каждого изменения DI/кода.
+- Ошибки применения аннотаций появляются на этапе генерации.
+- Никогда не редактируйте .g.dart файлы вручную.
+

+# Circular Dependency Detection
+
+CherryPick provides robust circular dependency detection to prevent infinite loops and stack overflow errors in your dependency injection setup.
+
+## What are Circular Dependencies?
+
+Circular dependencies occur when two or more services depend on each other directly or indirectly, creating a cycle in the dependency graph.
+
+### Example of circular dependencies within a scope
+
+```dart
+class UserService {
+  final OrderService orderService;
+  UserService(this.orderService);
+}
+
+class OrderService {
+  final UserService userService;
+  OrderService(this.userService);
+}
+```
+
+### Example of circular dependencies between scopes
+
+```dart
+// In parent scope
+class ParentService {
+  final ChildService childService;
+  ParentService(this.childService); // Gets from child scope
+}
+
+// In child scope
+class ChildService {
+  final ParentService parentService;
+  ChildService(this.parentService); // Gets from parent scope
+}
+```
+
+## Detection Types
+
+### 🔍 Local Detection
+
+Detects circular dependencies within a single scope. Fast and efficient.
+
+### 🌐 Global Detection
+
+Detects circular dependencies across the entire scope hierarchy. Slower but provides complete protection.
+
+## Usage
+
+### Local Detection
+
+```dart
+final scope = Scope(null);
+scope.enableCycleDetection(); // Enable local detection
+
+scope.installModules([
+  Module((bind) {
+    bind<UserService>().to((scope) => UserService(scope.resolve<OrderService>()));
+    bind<OrderService>().to((scope) => OrderService(scope.resolve<UserService>()));
+  }),
+]);
+
+try {
+  final userService = scope.resolve<UserService>(); // Will throw CircularDependencyException
+} catch (e) {
+  print(e); // CircularDependencyException: Circular dependency detected
+}
+```
+
+### Global Detection
+
+```dart
+// Enable global detection for all scopes
+CherryPick.enableGlobalCrossScopeCycleDetection();
+
+final rootScope = CherryPick.openGlobalSafeRootScope();
+final childScope = rootScope.openSubScope();
+
+// Configure dependencies that create cross-scope cycles
+rootScope.installModules([
+  Module((bind) {
+    bind<ParentService>().to((scope) => ParentService(childScope.resolve<ChildService>()));
+  }),
+]);
+
+childScope.installModules([
+  Module((bind) {
+    bind<ChildService>().to((scope) => ChildService(rootScope.resolve<ParentService>()));
+  }),
+]);
+
+try {
+  final parentService = rootScope.resolve<ParentService>(); // Will throw CircularDependencyException
+} catch (e) {
+  print(e); // CircularDependencyException with detailed chain information
+}
+```
+
+## CherryPick Helper API
+
+### Global Settings
+
+```dart
+// Enable/disable local detection globally
+CherryPick.enableGlobalCycleDetection();
+CherryPick.disableGlobalCycleDetection();
+
+// Enable/disable global cross-scope detection
+CherryPick.enableGlobalCrossScopeCycleDetection();
+CherryPick.disableGlobalCrossScopeCycleDetection();
+
+// Check current settings
+bool localEnabled = CherryPick.isGlobalCycleDetectionEnabled;
+bool globalEnabled = CherryPick.isGlobalCrossScopeCycleDetectionEnabled;
+```
+
+### Per-Scope Settings
+
+```dart
+// Enable/disable for specific scope
+CherryPick.enableCycleDetectionForScope(scope);
+CherryPick.disableCycleDetectionForScope(scope);
+
+// Enable/disable global detection for specific scope
+CherryPick.enableGlobalCycleDetectionForScope(scope);
+CherryPick.disableGlobalCycleDetectionForScope(scope);
+```
+
+### Safe Scope Creation
+
+```dart
+// Create scopes with detection automatically enabled
+final safeRootScope = CherryPick.openSafeRootScope(); // Local detection enabled
+final globalSafeRootScope = CherryPick.openGlobalSafeRootScope(); // Both local and global enabled
+final safeSubScope = CherryPick.openSafeSubScope(parentScope); // Inherits parent settings
+```
+
+## Performance Considerations
+
+| Detection Type | Overhead | Recommended Usage |
+|----------------|----------|-------------------|
+| **Local** | Minimal (~5%) | Development, Testing |
+| **Global** | Moderate (~15%) | Complex hierarchies, Critical features |
+| **Disabled** | None | Production (after testing) |
+
+### Recommendations
+
+- **Development**: Enable both local and global detection for maximum safety
+- **Testing**: Keep detection enabled to catch issues early
+- **Production**: Consider disabling for performance, but only after thorough testing
+
+```dart
+import 'package:flutter/foundation.dart';
+
+void configureCycleDetection() {
+  if (kDebugMode) {
+    // Enable full protection in debug mode
+    CherryPick.enableGlobalCycleDetection();
+    CherryPick.enableGlobalCrossScopeCycleDetection();
+  } else {
+    // Disable in release mode for performance
+    CherryPick.disableGlobalCycleDetection();
+    CherryPick.disableGlobalCrossScopeCycleDetection();
+  }
+}
+```
+
+## Architectural Patterns
+
+### Repository Pattern
+
+```dart
+// ✅ Correct: Repository doesn't depend on service
+class UserRepository {
+  final ApiClient apiClient;
+  UserRepository(this.apiClient);
+}
+
+class UserService {
+  final UserRepository repository;
+  UserService(this.repository);
+}
+
+// ❌ Incorrect: Circular dependency
+class UserRepository {
+  final UserService userService; // Don't do this!
+  UserRepository(this.userService);
+}
+```
+
+### Mediator Pattern
+
+```dart
+// ✅ Correct: Use mediator to break cycles
+abstract class EventBus {
+  void publish<T>(T event);
+  Stream<T> listen<T>();
+}
+
+class UserService {
+  final EventBus eventBus;
+  UserService(this.eventBus);
+  
+  void createUser(User user) {
+    // ... create user logic
+    eventBus.publish(UserCreatedEvent(user));
+  }
+}
+
+class OrderService {
+  final EventBus eventBus;
+  OrderService(this.eventBus) {
+    eventBus.listen<UserCreatedEvent>().listen(_onUserCreated);
+  }
+  
+  void _onUserCreated(UserCreatedEvent event) {
+    // React to user creation without direct dependency
+  }
+}
+```
+
+## Scope Hierarchy Best Practices
+
+### Proper Dependency Flow
+
+```dart
+// ✅ Correct: Dependencies flow downward in hierarchy
+// Root Scope: Core services
+final rootScope = CherryPick.openGlobalSafeRootScope();
+rootScope.installModules([
+  Module((bind) {
+    bind<DatabaseService>().singleton((scope) => DatabaseService());
+    bind<ApiClient>().singleton((scope) => ApiClient());
+  }),
+]);
+
+// Feature Scope: Feature-specific services
+final featureScope = rootScope.openSubScope();
+featureScope.installModules([
+  Module((bind) {
+    bind<UserRepository>().to((scope) => UserRepository(scope.resolve<ApiClient>()));
+    bind<UserService>().to((scope) => UserService(scope.resolve<UserRepository>()));
+  }),
+]);
+
+// UI Scope: UI-specific services
+final uiScope = featureScope.openSubScope();
+uiScope.installModules([
+  Module((bind) {
+    bind<UserController>().to((scope) => UserController(scope.resolve<UserService>()));
+  }),
+]);
+```
+
+### Avoid Cross-Scope Dependencies
+
+```dart
+// ❌ Incorrect: Child scope depending on parent's specific services
+childScope.installModules([
+  Module((bind) {
+    bind<ChildService>().to((scope) => 
+      ChildService(rootScope.resolve<ParentService>()) // Risky!
+    );
+  }),
+]);
+
+// ✅ Correct: Use interfaces and proper dependency injection
+abstract class IParentService {
+  void doSomething();
+}
+
+class ParentService implements IParentService {
+  void doSomething() { /* implementation */ }
+}
+
+// In root scope
+rootScope.installModules([
+  Module((bind) {
+    bind<IParentService>().to((scope) => ParentService());
+  }),
+]);
+
+// In child scope - resolve through normal hierarchy
+childScope.installModules([
+  Module((bind) {
+    bind<ChildService>().to((scope) => 
+      ChildService(scope.resolve<IParentService>()) // Safe!
+    );
+  }),
+]);
+```
+
+## Debug Mode
+
+### Resolution Chain Tracking
+
+```dart
+// Enable debug mode to track resolution chains
+final scope = CherryPick.openGlobalSafeRootScope();
+
+// Access current resolution chain for debugging
+print('Current resolution chain: ${scope.currentResolutionChain}');
+
+// Access global resolution chain
+print('Global resolution chain: ${GlobalCycleDetector.instance.currentGlobalResolutionChain}');
+```
+
+### Exception Details
+
+```dart
+try {
+  final service = scope.resolve<CircularService>();
+} on CircularDependencyException catch (e) {
+  print('Error: ${e.message}');
+  print('Dependency chain: ${e.dependencyChain.join(' -> ')}');
+  
+  // For global detection, additional context is available
+  if (e.message.contains('cross-scope')) {
+    print('This is a cross-scope circular dependency');
+  }
+}
+```
+
+## Testing Integration
+
+### Unit Tests
+
+```dart
+import 'package:test/test.dart';
+import 'package:cherrypick/cherrypick.dart';
+
+void main() {
+  group('Circular Dependency Detection', () {
+    setUp(() {
+      // Enable detection for tests
+      CherryPick.enableGlobalCycleDetection();
+      CherryPick.enableGlobalCrossScopeCycleDetection();
+    });
+    
+    tearDown(() {
+      // Clean up after tests
+      CherryPick.disableGlobalCycleDetection();
+      CherryPick.disableGlobalCrossScopeCycleDetection();
+    });
+    
+    test('should detect circular dependency', () {
+      final scope = CherryPick.openGlobalSafeRootScope();
+      
+      scope.installModules([
+        Module((bind) {
+          bind<ServiceA>().to((scope) => ServiceA(scope.resolve<ServiceB>()));
+          bind<ServiceB>().to((scope) => ServiceB(scope.resolve<ServiceA>()));
+        }),
+      ]);
+      
+      expect(
+        () => scope.resolve<ServiceA>(),
+        throwsA(isA<CircularDependencyException>()),
+      );
+    });
+  });
+}
+```
+
+### Integration Tests
+
+```dart
+testWidgets('should handle circular dependencies in widget tree', (tester) async {
+  // Enable detection
+  CherryPick.enableGlobalCycleDetection();
+  
+  await tester.pumpWidget(
+    CherryPickProvider(
+      create: () {
+        final scope = CherryPick.openGlobalSafeRootScope();
+        // Configure modules that might have cycles
+        return scope;
+      },
+      child: MyApp(),
+    ),
+  );
+  
+  // Test that circular dependencies are properly handled
+  expect(find.text('Error: Circular dependency detected'), findsNothing);
+});
+```
+
+## Migration Guide
+
+### From Version 2.1.x to 2.2.x
+
+1. **Update dependencies**:
+   ```yaml
+   dependencies:
+     cherrypick: ^2.2.0
+   ```
+
+2. **Enable detection in existing code**:
+   ```dart
+   // Before
+   final scope = Scope(null);
+   
+   // After - with local detection
+   final scope = CherryPick.openSafeRootScope();
+   
+   // Or with global detection
+   final scope = CherryPick.openGlobalSafeRootScope();
+   ```
+
+3. **Update error handling**:
+   ```dart
+   try {
+     final service = scope.resolve<MyService>();
+   } on CircularDependencyException catch (e) {
+     // Handle circular dependency errors
+     logger.error('Circular dependency detected: ${e.dependencyChain}');
+   }
+   ```
+
+4. **Configure for production**:
+   ```dart
+   void main() {
+     // Configure detection based on build mode
+     if (kDebugMode) {
+       CherryPick.enableGlobalCycleDetection();
+       CherryPick.enableGlobalCrossScopeCycleDetection();
+     }
+     
+     runApp(MyApp());
+   }
+   ```
+
+## API Reference

+
+### Exception Classes
+
+```dart
+class CircularDependencyException implements Exception {
+  final String message;
+  final List<String> dependencyChain;
+  
+  const CircularDependencyException(this.message, this.dependencyChain);
+  
+  @override
+  String toString() {
+    final chain = dependencyChain.join(' -> ');
+    return 'CircularDependencyException: $message\nDependency chain: $chain';
+  }
+}
+```
+
+## Best Practices
+
+### 1. Enable Detection During Development
+
+```dart
+void main() {
+  if (kDebugMode) {
+    CherryPick.enableGlobalCycleDetection();
+    CherryPick.enableGlobalCrossScopeCycleDetection();
+  }
+  
+  runApp(MyApp());
+}
+```
+
+### 2. Use Safe Scope Creation
+
+```dart
+// Instead of
+final scope = Scope(null);
+
+// Use
+final scope = CherryPick.openGlobalSafeRootScope();
+```
+
+### 3. Design Proper Architecture
+
+- Follow single responsibility principle
+- Use interfaces to decouple dependencies
+- Implement mediator pattern for complex interactions
+- Keep dependency flow unidirectional in scope hierarchy
+
+### 4. Handle Errors Gracefully
+
+```dart
+T resolveSafely<T>() {
+  try {
+    return scope.resolve<T>();
+  } on CircularDependencyException catch (e) {
+    logger.error('Circular dependency detected', e);
+    rethrow;
+  }
+}
+```
+
+### 5. Test Thoroughly
+
+- Write unit tests for dependency configurations
+- Use integration tests to verify complex scenarios
+- Enable detection in test environments
+- Test both positive and negative scenarios
+
+## Troubleshooting
+
+### Common Issues
+
+1. **False Positives**: If you're getting false circular dependency errors, check if you have proper async handling in your providers.
+
+2. **Performance Issues**: If global detection is too slow, consider using only local detection or disabling it in production.
+
+3. **Complex Hierarchies**: For very complex scope hierarchies, consider simplifying your architecture or using more interfaces.
+
+### Debug Tips
+
+1. **Check Resolution Chain**: Use `scope.currentResolutionChain` to see the current dependency resolution path.
+
+2. **Enable Logging**: Add logging to your providers to trace dependency resolution.
+
+3. **Simplify Dependencies**: Break complex dependencies into smaller, more manageable pieces.
+
+4. **Use Interfaces**: Abstract dependencies behind interfaces to reduce coupling.
+
+## Conclusion
+
+Circular dependency detection in CherryPick provides robust protection against infinite loops and stack overflow errors. By following the best practices and using the appropriate detection level for your use case, you can build reliable and maintainable dependency injection configurations.

+# Обнаружение циклических зависимостей
+
+CherryPick предоставляет надежное обнаружение циклических зависимостей для предотвращения бесконечных циклов и ошибок переполнения стека в вашей настройке внедрения зависимостей.
+
+## Что такое циклические зависимости?
+
+Циклические зависимости возникают, когда два или более сервиса зависят друг от друга прямо или косвенно, создавая цикл в графе зависимостей.
+
+### Пример циклических зависимостей в рамках скоупа
+
+```dart
+class UserService {
+  final OrderService orderService;
+  UserService(this.orderService);
+}
+
+class OrderService {
+  final UserService userService;
+  OrderService(this.userService);
+}
+```
+
+### Пример циклических зависимостей между скоупами
+
+```dart
+// В родительском скоупе
+class ParentService {
+  final ChildService childService;
+  ParentService(this.childService); // Получает из дочернего скоупа
+}
+
+// В дочернем скоупе
+class ChildService {
+  final ParentService parentService;
+  ChildService(this.parentService); // Получает из родительского скоупа
+}
+```
+
+## Типы обнаружения
+
+### 🔍 Локальное обнаружение
+
+Обнаруживает циклические зависимости в рамках одного скоупа. Быстрое и эффективное.
+
+### 🌐 Глобальное обнаружение
+
+Обнаруживает циклические зависимости во всей иерархии скоупов. Более медленное, но обеспечивает полную защиту.
+
+## Использование
+
+### Локальное обнаружение
+
+```dart
+final scope = Scope(null);
+scope.enableCycleDetection(); // Включить локальное обнаружение
+
+scope.installModules([
+  Module((bind) {
+    bind<UserService>().to((scope) => UserService(scope.resolve<OrderService>()));
+    bind<OrderService>().to((scope) => OrderService(scope.resolve<UserService>()));
+  }),
+]);
+
+try {
+  final userService = scope.resolve<UserService>(); // Выбросит CircularDependencyException
+} catch (e) {
+  print(e); // CircularDependencyException: Circular dependency detected
+}
+```
+
+### Глобальное обнаружение
+
+```dart
+// Включить глобальное обнаружение для всех скоупов
+CherryPick.enableGlobalCrossScopeCycleDetection();
+
+final rootScope = CherryPick.openGlobalSafeRootScope();
+final childScope = rootScope.openSubScope();
+
+// Настроить зависимости, которые создают межскоуповые циклы
+rootScope.installModules([
+  Module((bind) {
+    bind<ParentService>().to((scope) => ParentService(childScope.resolve<ChildService>()));
+  }),
+]);
+
+childScope.installModules([
+  Module((bind) {
+    bind<ChildService>().to((scope) => ChildService(rootScope.resolve<ParentService>()));
+  }),
+]);
+
+try {
+  final parentService = rootScope.resolve<ParentService>(); // Выбросит CircularDependencyException
+} catch (e) {
+  print(e); // CircularDependencyException с детальной информацией о цепочке
+}
+```
+
+## API CherryPick Helper
+
+### Глобальные настройки
+
+```dart
+// Включить/отключить локальное обнаружение глобально
+CherryPick.enableGlobalCycleDetection();
+CherryPick.disableGlobalCycleDetection();
+
+// Включить/отключить глобальное межскоуповое обнаружение
+CherryPick.enableGlobalCrossScopeCycleDetection();
+CherryPick.disableGlobalCrossScopeCycleDetection();
+
+// Проверить текущие настройки
+bool localEnabled = CherryPick.isGlobalCycleDetectionEnabled;
+bool globalEnabled = CherryPick.isGlobalCrossScopeCycleDetectionEnabled;
+```
+
+### Настройки для конкретного скоупа
+
+```dart
+// Включить/отключить для конкретного скоупа
+CherryPick.enableCycleDetectionForScope(scope);
+CherryPick.disableCycleDetectionForScope(scope);
+
+// Включить/отключить глобальное обнаружение для конкретного скоупа
+CherryPick.enableGlobalCycleDetectionForScope(scope);
+CherryPick.disableGlobalCycleDetectionForScope(scope);
+```
+
+### Безопасное создание скоупов
+
+```dart
+// Создать скоупы с автоматически включенным обнаружением
+final safeRootScope = CherryPick.openSafeRootScope(); // Локальное обнаружение включено
+final globalSafeRootScope = CherryPick.openGlobalSafeRootScope(); // Включены локальное и глобальное
+final safeSubScope = CherryPick.openSafeSubScope(parentScope); // Наследует настройки родителя
+```
+
+## Соображения производительности
+
+| Тип обнаружения | Накладные расходы | Рекомендуемое использование |
+|-----------------|-------------------|----------------------------|
+| **Локальное** | Минимальные (~5%) | Разработка, тестирование |
+| **Глобальное** | Умеренные (~15%) | Сложные иерархии, критические функции |
+| **Отключено** | Нет | Продакшн (после тестирования) |
+
+### Рекомендации
+
+- **Разработка**: Включите локальное и глобальное обнаружение для максимальной безопасности
+- **Тестирование**: Оставьте обнаружение включенным для раннего выявления проблем
+- **Продакшн**: Рассмотрите отключение для производительности, но только после тщательного тестирования
+
+```dart
+import 'package:flutter/foundation.dart';
+
+void configureCycleDetection() {
+  if (kDebugMode) {
+    // Включить полную защиту в режиме отладки
+    CherryPick.enableGlobalCycleDetection();
+    CherryPick.enableGlobalCrossScopeCycleDetection();
+  } else {
+    // Отключить в релизном режиме для производительности
+    CherryPick.disableGlobalCycleDetection();
+    CherryPick.disableGlobalCrossScopeCycleDetection();
+  }
+}
+```
+
+## Архитектурные паттерны
+
+### Паттерн Repository
+
+```dart
+// ✅ Правильно: Repository не зависит от сервиса
+class UserRepository {
+  final ApiClient apiClient;
+  UserRepository(this.apiClient);
+}
+
+class UserService {
+  final UserRepository repository;
+  UserService(this.repository);
+}
+
+// ❌ Неправильно: Циклическая зависимость
+class UserRepository {
+  final UserService userService; // Не делайте так!
+  UserRepository(this.userService);
+}
+```
+
+### Паттерн Mediator
+
+```dart
+// ✅ Правильно: Используйте медиатор для разрыва циклов
+abstract class EventBus {
+  void publish<T>(T event);
+  Stream<T> listen<T>();
+}
+
+class UserService {
+  final EventBus eventBus;
+  UserService(this.eventBus);
+  
+  void createUser(User user) {
+    // ... логика создания пользователя
+    eventBus.publish(UserCreatedEvent(user));
+  }
+}
+
+class OrderService {
+  final EventBus eventBus;
+  OrderService(this.eventBus) {
+    eventBus.listen<UserCreatedEvent>().listen(_onUserCreated);
+  }
+  
+  void _onUserCreated(UserCreatedEvent event) {
+    // Реагировать на создание пользователя без прямой зависимости
+  }
+}
+```
+
+## Лучшие практики иерархии скоупов
+
+### Правильный поток зависимостей
+
+```dart
+// ✅ Правильно: Зависимости текут вниз по иерархии
+// Корневой скоуп: Основные сервисы
+final rootScope = CherryPick.openGlobalSafeRootScope();
+rootScope.installModules([
+  Module((bind) {
+    bind<DatabaseService>().singleton((scope) => DatabaseService());
+    bind<ApiClient>().singleton((scope) => ApiClient());
+  }),
+]);
+
+// Скоуп функции: Сервисы, специфичные для функции
+final featureScope = rootScope.openSubScope();
+featureScope.installModules([
+  Module((bind) {
+    bind<UserRepository>().to((scope) => UserRepository(scope.resolve<ApiClient>()));
+    bind<UserService>().to((scope) => UserService(scope.resolve<UserRepository>()));
+  }),
+]);
+
+// UI скоуп: Сервисы, специфичные для UI
+final uiScope = featureScope.openSubScope();
+uiScope.installModules([
+  Module((bind) {
+    bind<UserController>().to((scope) => UserController(scope.resolve<UserService>()));
+  }),
+]);
+```
+
+### Избегайте межскоуповых зависимостей
+
+```dart
+// ❌ Неправильно: Дочерний скоуп зависит от конкретных сервисов родителя
+childScope.installModules([
+  Module((bind) {
+    bind<ChildService>().to((scope) => 
+      ChildService(rootScope.resolve<ParentService>()) // Рискованно!
+    );
+  }),
+]);
+
+// ✅ Правильно: Используйте интерфейсы и правильное внедрение зависимостей
+abstract class IParentService {
+  void doSomething();
+}
+
+class ParentService implements IParentService {
+  void doSomething() { /* реализация */ }
+}
+
+// В корневом скоупе
+rootScope.installModules([
+  Module((bind) {
+    bind<IParentService>().to((scope) => ParentService());
+  }),
+]);
+
+// В дочернем скоупе - разрешение через обычную иерархию
+childScope.installModules([
+  Module((bind) {
+    bind<ChildService>().to((scope) => 
+      ChildService(scope.resolve<IParentService>()) // Безопасно!
+    );
+  }),
+]);
+```
+
+## Режим отладки
+
+### Отслеживание цепочки разрешения
+
+```dart
+// Включить режим отладки для отслеживания цепочек разрешения
+final scope = CherryPick.openGlobalSafeRootScope();
+
+// Доступ к текущей цепочке разрешения для отладки
+print('Текущая цепочка разрешения: ${scope.currentResolutionChain}');
+
+// Доступ к глобальной цепочке разрешения
+print('Глобальная цепочка разрешения: ${GlobalCycleDetector.instance.currentGlobalResolutionChain}');
+```
+
+### Детали исключений
+
+```dart
+try {
+  final service = scope.resolve<CircularService>();
+} on CircularDependencyException catch (e) {
+  print('Ошибка: ${e.message}');
+  print('Цепочка зависимостей: ${e.dependencyChain.join(' -> ')}');
+  
+  // Для глобального обнаружения доступен дополнительный контекст
+  if (e.message.contains('cross-scope')) {
+    print('Это межскоуповая циклическая зависимость');
+  }
+}
+```
+
+## Интеграция с тестированием
+
+### Модульные тесты
+
+```dart
+import 'package:test/test.dart';
+import 'package:cherrypick/cherrypick.dart';
+
+void main() {
+  group('Обнаружение циклических зависимостей', () {
+    setUp(() {
+      // Включить обнаружение для тестов
+      CherryPick.enableGlobalCycleDetection();
+      CherryPick.enableGlobalCrossScopeCycleDetection();
+    });
+    
+    tearDown(() {
+      // Очистка после тестов
+      CherryPick.disableGlobalCycleDetection();
+      CherryPick.disableGlobalCrossScopeCycleDetection();
+    });
+    
+    test('должен обнаружить циклическую зависимость', () {
+      final scope = CherryPick.openGlobalSafeRootScope();
+      
+      scope.installModules([
+        Module((bind) {
+          bind<ServiceA>().to((scope) => ServiceA(scope.resolve<ServiceB>()));
+          bind<ServiceB>().to((scope) => ServiceB(scope.resolve<ServiceA>()));
+        }),
+      ]);
+      
+      expect(
+        () => scope.resolve<ServiceA>(),
+        throwsA(isA<CircularDependencyException>()),
+      );
+    });
+  });
+}
+```
+
+### Интеграционные тесты
+
+```dart
+testWidgets('должен обрабатывать циклические зависимости в дереве виджетов', (tester) async {
+  // Включить обнаружение
+  CherryPick.enableGlobalCycleDetection();
+  
+  await tester.pumpWidget(
+    CherryPickProvider(
+      create: () {
+        final scope = CherryPick.openGlobalSafeRootScope();
+        // Настроить модули, которые могут иметь циклы
+        return scope;
+      },
+      child: MyApp(),
+    ),
+  );
+  
+  // Проверить, что циклические зависимости правильно обрабатываются
+  expect(find.text('Ошибка: Обнаружена циклическая зависимость'), findsNothing);
+});
+```
+
+## Руководство по миграции
+
+### С версии 2.1.x на 2.2.x
+
+1. **Обновите зависимости**:
+   ```yaml
+   dependencies:
+     cherrypick: ^2.2.0
+   ```
+
+2. **Включите обнаружение в существующем коде**:
+   ```dart
+   // Раньше
+   final scope = Scope(null);
+   
+   // Теперь - с локальным обнаружением
+   final scope = CherryPick.openSafeRootScope();
+   
+   // Или с глобальным обнаружением
+   final scope = CherryPick.openGlobalSafeRootScope();
+   ```
+
+3. **Обновите обработку ошибок**:
+   ```dart
+   try {
+     final service = scope.resolve<MyService>();
+   } on CircularDependencyException catch (e) {
+     // Обработать ошибки циклических зависимостей
+     logger.error('Обнаружена циклическая зависимость: ${e.dependencyChain}');
+   }
+   ```
+
+4. **Настройте для продакшна**:
+   ```dart
+   void main() {
+     // Настроить обнаружение в зависимости от режима сборки
+     if (kDebugMode) {
+       CherryPick.enableGlobalCycleDetection();
+       CherryPick.enableGlobalCrossScopeCycleDetection();
+     }
+     
+     runApp(MyApp());
+   }
+   ```
+
+## Справочник API
+
+### Методы Scope
+
+```dart
+class Scope {
+  // Локальное обнаружение циклов
+  void enableCycleDetection();
+  void disableCycleDetection();
+  bool get isCycleDetectionEnabled;
+  List<String> get currentResolutionChain;
+  
+  // Глобальное обнаружение циклов
+  void enableGlobalCycleDetection();
+  void disableGlobalCycleDetection();
+  bool get isGlobalCycleDetectionEnabled;
+}
+```
+
+### Методы CherryPick Helper
+
+```dart
+class CherryPick {
+  // Глобальные настройки
+  static void enableGlobalCycleDetection();
+  static void disableGlobalCycleDetection();
+  static bool get isGlobalCycleDetectionEnabled;
+  
+  static void enableGlobalCrossScopeCycleDetection();
+  static void disableGlobalCrossScopeCycleDetection();
+  static bool get isGlobalCrossScopeCycleDetectionEnabled;
+  
+  // Настройки для конкретного скоупа
+  static void enableCycleDetectionForScope(Scope scope);
+  static void disableCycleDetectionForScope(Scope scope);
+  static void enableGlobalCycleDetectionForScope(Scope scope);
+  static void disableGlobalCycleDetectionForScope(Scope scope);
+  
+  // Безопасное создание скоупов
+  static Scope openSafeRootScope();
+  static Scope openGlobalSafeRootScope();
+  static Scope openSafeSubScope(Scope parent);
+}
+```
+
+### Классы исключений
+
+```dart
+class CircularDependencyException implements Exception {
+  final String message;
+  final List<String> dependencyChain;
+  
+  const CircularDependencyException(this.message, this.dependencyChain);
+  
+  @override
+  String toString() {
+    final chain = dependencyChain.join(' -> ');
+    return 'CircularDependencyException: $message\nЦепочка зависимостей: $chain';
+  }
+}
+```
+
+## Лучшие практики
+
+### 1. Включайте обнаружение во время разработки
+
+```dart
+void main() {
+  if (kDebugMode) {
+    CherryPick.enableGlobalCycleDetection();
+    CherryPick.enableGlobalCrossScopeCycleDetection();
+  }
+  
+  runApp(MyApp());
+}
+```
+
+### 2. Используйте безопасное создание скоупов
+
+```dart
+// Вместо
+final scope = Scope(null);
+
+// Используйте
+final scope = CherryPick.openGlobalSafeRootScope();
+```
+
+### 3. Проектируйте правильную архитектуру
+
+- Следуйте принципу единственной ответственности
+- Используйте интерфейсы для разделения зависимостей
+- Реализуйте паттерн медиатор для сложных взаимодействий
+- Поддерживайте однонаправленный поток зависимостей в иерархии скоупов
+
+### 4. Обрабатывайте ошибки корректно
+
+```dart
+T resolveSafely<T>() {
+  try {
+    return scope.resolve<T>();
+  } on CircularDependencyException catch (e) {
+    logger.error('Обнаружена циклическая зависимость', e);
+    rethrow;
+  }
+}
+```
+
+### 5. Тестируйте тщательно
+
+- Пишите модульные тесты для конфигураций зависимостей
+- Используйте интеграционные тесты для проверки сложных сценариев
+- Включайте обнаружение в тестовых средах
+- Тестируйте как положительные, так и отрицательные сценарии
+
+## Устранение неполадок
+
+### Распространенные проблемы
+
+1. **Ложные срабатывания**: Если вы получаете ложные ошибки циклических зависимостей, проверьте правильность обработки async в ваших провайдерах.
+
+2. **Проблемы производительности**: Если глобальное обнаружение слишком медленное, рассмотрите использование только локального обнаружения или отключение в продакшне.
+
+3. **Сложные иерархии**: Для очень сложных иерархий скоупов рассмотрите упрощение архитектуры или использование большего количества интерфейсов.
+
+### Советы по отладке
+
+1. **Проверьте цепочку разрешения**: Используйте `scope.currentResolutionChain` для просмотра текущего пути разрешения зависимостей.
+
+2. **Включите логирование**: Добавьте логирование в ваши провайдеры для трассировки разрешения зависимостей.
+
+3. **Упростите зависимости**: Разбейте сложные зависимости на более мелкие, управляемые части.
+
+4. **Используйте интерфейсы**: Абстрагируйте зависимости за интерфейсами для уменьшения связанности.
+
+## Заключение
+
+Обнаружение циклических зависимостей в CherryPick обеспечивает надежную защиту от бесконечных циклов и ошибок переполнения стека. Следуя лучшим практикам и используя подходящий уровень обнаружения для вашего случая использования, вы можете создавать надежные и поддерживаемые конфигурации внедрения зависимостей.

+# Full Guide to CherryPick DI for Dart and Flutter: Dependency Injection with Annotations and Automatic Code Generation
+
+**CherryPick** is a powerful tool for dependency injection in Dart and Flutter projects. It offers a modern approach with code generation, async providers, named and parameterized bindings, and field injection using annotations.
+
+> Tools:  
+> - [`cherrypick`](https://pub.dev/packages/cherrypick) — runtime DI core  
+> - [`cherrypick_annotations`](https://pub.dev/packages/cherrypick_annotations) — DI annotations  
+> - [`cherrypick_generator`](https://pub.dev/packages/cherrypick_generator) — DI code generation  
+>
+
+---
+
+## CherryPick advantages vs other DI frameworks
+
+- 📦 Simple declarative API for registering and resolving dependencies
+- ⚡️ Full support for both sync and async registrations
+- 🧩 DI via annotations with codegen, including advanced field injection
+- 🏷️ Named bindings for multiple interface implementations
+- 🏭 Parameterized bindings for runtime factories (e.g., by ID)
+- 🌲 Flexible scope system for dependency isolation and hierarchy
+- 🕹️ Optional resolution (`tryResolve`)
+- 🐞 Clear compile-time errors for invalid annotation or DI configuration
+
+---
+
+## How CherryPick works: core concepts
+
+### Dependency registration (bindings)
+
+```dart
+bind<MyService>().toProvide(() => MyServiceImpl());
+bind<MyRepository>().toProvideAsync(() async => await initRepo());
+bind<UserService>().toProvideWithParams((id) => UserService(id));
+
+// Singleton
+bind<MyApi>().toProvide(() => MyApi()).singleton();
+
+// Register an already created object
+final config = AppConfig.dev();
+bind<AppConfig>().toInstance(config);
+
+// Register an already running Future/async value
+final setupFuture = loadEnvironment();
+bind<Environment>().toInstanceAsync(setupFuture);
+```
+
+- **toProvide** — regular sync factory
+- **toProvideAsync** — async factory (if you need to await a Future)
+- **toProvideWithParams / toProvideAsyncWithParams** — factories with runtime parameters
+- **toInstance** — registers an already created object as a dependency
+- **toInstanceAsync** — registers an already started Future as an async dependency
+
+### Named bindings
+
+You can register several implementations of an interface under different names:
+
+```dart
+bind<ApiClient>().toProvide(() => ApiClientProd()).withName('prod');
+bind<ApiClient>().toProvide(() => ApiClientMock()).withName('mock');
+
+// Resolving by name:
+final api = scope.resolve<ApiClient>(named: 'mock');
+```
+
+### Lifecycle: singleton
+
+- `.singleton()` — single instance per Scope lifetime
+- By default, every resolve creates a new object
+
+### Parameterized bindings
+
+Allows you to create dependencies with runtime parameters, e.g., a service for a user with a given ID:
+
+```dart
+bind<UserService>().toProvideWithParams((userId) => UserService(userId));
+
+// Resolve:
+final userService = scope.resolve<UserService>(params: '123');
+```
+
+---
+
+## Scope management: dependency hierarchy
+
+For most business cases, a single root scope is enough, but CherryPick supports nested scopes:
+
+```dart
+final rootScope = CherryPick.openRootScope();
+final profileScope = rootScope.openSubScope('profile')
+  ..installModules([ProfileModule()]);
+```
+
+- **Subscope** can override parent dependencies.
+- When resolving, first checks its own scope, then up the hierarchy.
+
+
+## Managing names and scope hierarchy (subscopes) in CherryPick
+
+CherryPick supports nested scopes, each can be "root" or a child. For accessing/managing the hierarchy, CherryPick uses scope names (strings) as well as convenient open/close methods.
+
+### Open subScope by name
+
+CherryPick uses separator-delimited strings to search and build scope trees, for example:
+
+```dart
+final subScope = CherryPick.openScope(scopeName: 'profile.settings');
+```
+
+- Here, `'profile.settings'` will open 'profile' subscope in root, then 'settings' subscope in 'profile'.
+- Default separator is a dot (`.`), can be changed via `separator` argument.
+
+**Example with another separator:**
+
+```dart
+final subScope = CherryPick.openScope(
+  scopeName: 'project>>dev>>api',
+  separator: '>>',
+);
+```
+
+### Hierarchy & access
+
+Each hierarchy level is a separate scope.  
+This is convenient for restricting/localizing dependencies, for example:  
+- `main.profile` — dependencies only for user profile  
+- `main.profile.details` — even narrower context
+
+### Closing subscopes
+
+To close a specific subScope, use the same path:
+
+```dart
+CherryPick.closeScope(scopeName: 'profile.settings');
+```
+
+- Closing a top-level scope (`profile`) wipes all children too.
+
+### Methods summary
+
+| Method                    | Description                                             |
+|---------------------------|--------------------------------------------------------|
+| `openRootScope()`         | Open/get root scope                                    |
+| `closeRootScope()`        | Close root scope, remove all dependencies              |
+| `openScope(scopeName)`    | Open scope(s) by name & hierarchy (`'a.b.c'`)          |
+| `closeScope(scopeName)`   | Close specified scope or subScope                      |
+
+---
+
+**Recommendations:**  
+Use meaningful names and dot notation for scope structuring in large apps—this improves readability and dependency management on any level.
+
+---
+
+**Example:**
+
+```dart
+// Opens scopes by hierarchy: app -> module -> page
+final scope = CherryPick.openScope(scopeName: 'app.module.page');
+
+// Closes 'module' and all nested subscopes
+CherryPick.closeScope(scopeName: 'app.module');
+```
+
+---
+
+This lets you scale CherryPick DI for any app complexity!
+
+---
+
+## Safe dependency resolution
+
+If not sure a dependency exists, use tryResolve/tryResolveAsync:
+
+```dart
+final service = scope.tryResolve<OptionalService>(); // returns null if not exists
+```
+
+---
+
+## Dependency injection with annotations & code generation
+
+CherryPick supports DI with annotations, letting you eliminate manual DI setup.
+
+### Annotation structure
+
+| Annotation     | Purpose                   | Where to use                      |
+|---------------|---------------------------|------------------------------------|
+| `@module`     | DI module                 | Classes                            |
+| `@singleton`  | Singleton                 | Module methods                     |
+| `@instance`   | New object                | Module methods                     |
+| `@provide`    | Provider                  | Methods (with DI params)           |
+| `@named`      | Named binding             | Method argument/Class fields        |
+| `@params`     | Parameter passing         | Provider argument                  |
+| `@injectable` | Field injection support   | Classes                            |
+| `@inject`     | Auto-injection            | Class fields                       |
+| `@scope`      | Scope/realm               | Class fields                       |
+
+### Example DI module
+
+```dart
+import 'package:cherrypick_annotations/cherrypick_annotations.dart';
+
+@module()
+abstract class AppModule extends Module {
+  @singleton()
+  @provide()
+  ApiClient apiClient() => ApiClient();
+
+  @provide()
+  UserService userService(ApiClient api) => UserService(api);
+
+  @singleton()
+  @provide()
+  @named('mock')
+  ApiClient mockApiClient() => ApiClientMock();
+}
+```
+- Methods annotated with `@provide` become DI factories.
+- Add other annotations to specify binding type or name.
+
+Generated code will look like:
+
+```dart
+class $AppModule extends AppModule {
+  @override
+  void builder(Scope currentScope) {
+    bind<ApiClient>().toProvide(() => apiClient()).singleton();
+    bind<UserService>().toProvide(() => userService(currentScope.resolve<ApiClient>()));
+    bind<ApiClient>().toProvide(() => mockApiClient()).withName('mock').singleton();
+  }  
+}
+```
+
+### Example: field injection
+
+```dart
+@injectable()
+class ProfileBloc with _$ProfileBloc {
+  @inject()
+  late final AuthService auth;
+
+  @inject()
+  @named('admin')
+  late final UserService adminUser;
+  
+  ProfileBloc() {
+    _inject(this); // injectFields — generated method
+  }
+}
+```
+- Generator creates a mixin (`_$ProfileBloc`) which automatically resolves and injects dependencies into fields.
+- The `@named` annotation links a field to a named implementation.
+
+Example generated code:
+
+```dart
+mixin $ProfileBloc {
+  @override
+  void _inject(ProfileBloc instance) {
+    instance.auth = CherryPick.openRootScope().resolve<AuthService>();
+    instance.adminUser = CherryPick.openRootScope().resolve<UserService>(named: 'admin');
+  }  
+}
+```
+
+### How to connect it
+
+```dart
+void main() async {
+  final scope = CherryPick.openRootScope();
+  scope.installModules([
+    $AppModule(),
+  ]);
+  // DI via field injection
+  final bloc = ProfileBloc();
+  runApp(MyApp(bloc: bloc));
+}
+```
+
+---
+
+## Async dependencies
+
+For async providers, use `toProvideAsync`, and resolve them with `resolveAsync`:
+
+```dart
+bind<RemoteConfig>().toProvideAsync(() async => await RemoteConfig.load());
+
+// Usage:
+final config = await scope.resolveAsync<RemoteConfig>();
+```
+
+---
+
+## Validation and diagnostics
+
+- If you use incorrect annotations or DI config, you'll get clear compile-time errors.
+- Binding errors are found during code generation, minimizing runtime issues and speeding up development.
+
+---
+
+## Flutter integration: cherrypick_flutter
+
+### What it is
+
+[`cherrypick_flutter`](https://pub.dev/packages/cherrypick_flutter) is the integration package for CherryPick DI in Flutter. It provides a convenient `CherryPickProvider` widget which sits in your widget tree and gives access to the root DI scope (and subscopes) from context.
+
+### Features
+
+- **Global DI Scope Access:**  
+  Use `CherryPickProvider` to access rootScope and subscopes anywhere in the widget tree.
+- **Context integration:**  
+  Use `CherryPickProvider.of(context)` for DI access inside your widgets.
+
+### Usage Example
+
+```dart
+import 'package:flutter/material.dart';
+import 'package:cherrypick_flutter/cherrypick_flutter.dart';
+
+void main() {
+  runApp(
+    CherryPickProvider(
+      child: MyApp(),
+    ),
+  );
+}
+
+class MyApp extends StatelessWidget {
+  @override
+  Widget build(BuildContext context) {
+    final rootScope = CherryPickProvider.of(context).openRootScope();
+
+    return MaterialApp(
+      home: Scaffold(
+        body: Center(
+          child: Text(
+            rootScope.resolve<AppService>().getStatus(),
+          ),
+        ),
+      ),
+    );
+  }
+}
+```
+
+- Here, `CherryPickProvider` wraps the app and gives DI scope access via context.
+- You can create subscopes, e.g. for screens or modules:  
+  `final subScope = CherryPickProvider.of(context).openSubScope(scopeName: "profileFeature");`
+
+---
+## CherryPick is not just for Flutter!
+
+You can use CherryPick in Dart CLI, server apps, and microservices. All major features work without Flutter.
+
+---
+
+## CherryPick Example Project: Step by Step
+
+1. Add dependencies:
+    ```yaml
+    dependencies:
+      cherrypick: ^1.0.0
+      cherrypick_annotations: ^1.0.0
+
+    dev_dependencies:
+      build_runner: ^2.0.0
+      cherrypick_generator: ^1.0.0
+    ```
+
+2. Describe your modules using annotations.
+
+3. To generate DI code:
+    ```shell
+    dart run build_runner build --delete-conflicting-outputs
+    ```
+
+4. Enjoy modern DI with no boilerplate!
+
+---
+
+## Conclusion
+
+**CherryPick** is a modern DI solution for Dart and Flutter, combining a concise API and advanced annotation/codegen features. Scopes, parameterized providers, named bindings, and field-injection make it great for both small and large-scale projects.
+
+**Full annotation list and their purposes:**

+# Полный гайд по CherryPick DI для Dart и Flutter: внедрение зависимостей с аннотациями и автоматической генерацией кода
+
+**CherryPick** — это мощный инструмент для инъекции зависимостей в проектах на Dart и Flutter. Он предлагает современный подход с поддержкой генерации кода, асинхронных провайдеров, именованных и параметризируемых биндингов, а также field injection с использованием аннотаций.
+
+> Инструменты:  
+> - [`cherrypick`](https://pub.dev/packages/cherrypick) — runtime DI core  
+> - [`cherrypick_annotations`](https://pub.dev/packages/cherrypick_annotations) — аннотации для DI  
+> - [`cherrypick_generator`](https://pub.dev/packages/cherrypick_generator) — генерация DI-кода  
+>
+
+---
+
+## Преимущества CherryPick по сравнению с другими DI-фреймворками
+
+- 📦 Простой декларативный API для регистрации и разрешения зависимостей.
+- ⚡️ Полная поддержка синхронных _и_ асинхронных регистраций.
+- 🧩 DI через аннотации с автогенерацией кода, включая field injection.
+- 🏷️ Именованные зависимости (named bindings).
+- 🏭 Параметризация биндингов для runtime-использования фабрик.
+- 🌲 Гибкая система Scope'ов для изоляции и иерархии зависимостей.
+- 🕹️ Опциональное разрешение (tryResolve).
+- 🐞 Ясные compile-time ошибки при неправильной аннотации или неверном DI-описании.
+
+---
+
+## Как работает CherryPick: основные концепции
+
+### Регистрация зависимостей: биндинги
+
+```dart
+bind<MyService>().toProvide(() => MyServiceImpl());
+bind<MyRepository>().toProvideAsync(() async => await initRepo());
+bind<UserService>().toProvideWithParams((id) => UserService(id));
+
+// Singleton
+bind<MyApi>().toProvide(() => MyApi()).singleton();
+
+// Зарегистрировать уже существующий объект
+final config = AppConfig.dev();
+bind<AppConfig>().toInstance(config);
+
+// Зарегистрировать уже существующий Future/асинхронное значение
+final setupFuture = loadEnvironment();
+bind<Environment>().toInstanceAsync(setupFuture);
+```
+
+
+- **toProvide** — обычная синхронная фабрика.
+- **toProvideAsync** — асинхронная фабрика (например, если нужно дожидаться Future).
+- **toProvideWithParams / toProvideAsyncWithParams** — фабрики с параметрами.
+- **toInstance** — регистрирует уже созданный экземпляр класса как зависимость.
+- **toInstanceAsync** — регистрирует уже запущенный Future, как асинхронную зависимость.
+
+### Именованные биндинги (Named)
+
+Можно регистрировать несколько реализаций одного интерфейса под разными именами:
+
+```dart
+bind<ApiClient>().toProvide(() => ApiClientProd()).withName('prod');
+bind<ApiClient>().toProvide(() => ApiClientMock()).withName('mock');
+
+// Получение по имени:
+final api = scope.resolve<ApiClient>(named: 'mock');
+```
+
+### Жизненный цикл: singleton
+
+- `.singleton()` — один инстанс на всё время жизни Scope.
+- По умолчанию каждый resolve создаёт новый объект.
+
+### Параметрические биндинги
+
+Позволяют создавать зависимости с runtime-параметрами — например, сервис для пользователя с ID:
+
+```dart
+bind<UserService>().toProvideWithParams((userId) => UserService(userId));
+
+// Получение
+final userService = scope.resolve<UserService>(params: '123');
+```
+
+---
+
+## Управление Scope'ами: иерархия зависимостей
+
+Для большинства бизнес-кейсов достаточно одного Scope (root), но CherryPick поддерживает создание вложенных Scope:
+
+```dart
+final rootScope = CherryPick.openRootScope();
+final profileScope = rootScope.openSubScope('profile')
+    ..installModules([ProfileModule()]);
+```
+
+- **Под-скоуп** может переопределять зависимости родителя.
+- При разрешении сначала проверяется свой Scope, потом иерархия вверх.
+
+
+## Работа с именованием и иерархией подскоупов (subscopes) в CherryPick
+
+CherryPick поддерживает вложенные области видимости (scopes), где каждый scope может быть как "корневым", так и дочерним. Для доступа и управления иерархией используется понятие **scope name** (имя области видимости), а также удобные методы для открытия и закрытия скопов по строковым идентификаторам.
+
+### Открытие subScope по имени
+
+CherryPick использует строки с разделителями для поиска и построения дерева областей видимости. Например:
+
+```dart
+final subScope = CherryPick.openScope(scopeName: 'profile.settings');
+```
+
+- Здесь `'profile.settings'` означает, что сначала откроется подскоуп `profile` у rootScope, затем — подскоуп `settings` у `profile`.
+- Разделитель по умолчанию — точка (`.`). Его можно изменить, указав `separator` аргументом.
+
+**Пример с другим разделителем:**
+
+```dart
+final subScope = CherryPick.openScope(
+  scopeName: 'project>>dev>>api',
+  separator: '>>',
+);
+```
+
+### Иерархия и доступ
+
+Каждый уровень иерархии соответствует отдельному scope.  
+Это удобно для ограничения и локализации зависимостей, например:  
+- `main.profile` — зависимости только для профиля пользователя  
+- `main.profile.details` — ещё более "узкая" область видимости
+
+### Закрытие подскоупов
+
+Чтобы закрыть конкретный subScope, используйте тот же путь:
+
+```dart
+CherryPick.closeScope(scopeName: 'profile.settings');
+```
+
+- Если закрываете верхний скоуп (`profile`), все дочерние тоже будут очищены.
+
+### Кратко о методах
+
+| Метод                    | Описание                                                |
+|--------------------------|--------------------------------------------------------|
+| `openRootScope()`        | Открыть/получить корневой scope                        |
+| `closeRootScope()`       | Закрыть root scope, удалить все зависимости            |
+| `openScope(scopeName)`   | Открыть scope(ы) по имени с иерархией (`'a.b.c'`)      |
+| `closeScope(scopeName)`  | Закрыть указанный scope или subscope                   |
+
+---
+
+**Рекомендации:**  
+Используйте осмысленные имена и "точечную" нотацию для структурирования зон видимости в крупных приложениях — это повысит читаемость и позволит удобно управлять зависимостями на любых уровнях.
+
+---
+
+**Пример:**
+
+```dart
+// Откроет scopes по иерархии: app -> module -> page
+final scope = CherryPick.openScope(scopeName: 'app.module.page');
+
+// Закроет 'module' и все вложенные subscopes
+CherryPick.closeScope(scopeName: 'app.module');
+```
+
+---
+
+Это позволит масштабировать DI-подход CherryPick в приложениях любой сложности!
+
+---
+
+## Безопасное разрешение зависимостей
+
+Если не уверены, что нужная зависимость есть, используйте tryResolve/tryResolveAsync:
+
+```dart
+final service = scope.tryResolve<OptionalService>(); // вернет null, если нет
+```
+
+---
+
+## Внедрение зависимостей через аннотации и автогенерацию
+
+CherryPick поддерживает DI через аннотации, что позволяет полностью избавиться от ручного внедрения зависимостей.
+
+### Структура аннотаций
+
+| Аннотация     | Для чего                  | Где применяют                    |
+| ------------- | ------------------------- | -------------------------------- |
+| `@module`     | DI-модуль                 | Классы                           |
+| `@singleton`  | Singleton                 | Методы класса                    |
+| `@instance`   | Новый объект              | Методы класса                    |
+| `@provide`    | Провайдер                 | Методы (с DI params)             |
+| `@named`      | Именованный биндинг       | Аргумент метода/Аттрибуты класса |
+| `@params`     | Передача параметров       | Аргумент провайдера              |
+| `@injectable` | Поддержка field injection | Классы                           |
+| `@inject`     | Автовнедрение             | Аттрибуты класса                 |
+| `@scope`      | Scope/realm               | Аттрибуты класса                 |
+
+### Пример DI-модуля
+
+```dart
+import 'package:cherrypick_annotations/cherrypick_annotations.dart';
+
+@module()
+abstract class AppModule extends Module {
+  @singleton()
+  @provide()
+  ApiClient apiClient() => ApiClient();
+
+  @provide()
+  UserService userService(ApiClient api) => UserService(api);
+
+  @singleton()
+  @provide()
+  @named('mock')
+  ApiClient mockApiClient() => ApiClientMock();
+}
+```
+- Методы, отмеченные `@provide`, становятся фабриками DI.  
+- Можно добавлять другие аннотации для уточнения типа биндинга, имени.
+
+Сгенерированный код будет выглядеть вот таким образом:
+
+```dart
+class $AppModule extends AppModule {
+	@override
+	void builder(Scope currentScope) {
+		bind<ApiClient>().toProvide(() => apiClient()).singelton();
+		bind<UserService>().toProvide(() => userService(currentScope.resolve<ApiClient>()));
+		bind<ApiClient>().toProvide(() => mockApiClient()).withName('mock').singelton();
+	}	
+}
+```
+
+
+### Пример инъекций зависимостей через field injection
+
+```dart
+@injectable()
+class ProfileBloc with _$ProfileBloc {
+  @inject()
+  late final AuthService auth;
+
+  @inject()
+  @named('admin')
+  late final UserService adminUser;
+  
+  ProfileBloc() {
+    _inject(this); // injectFields — сгенерированный метод
+  }
+}
+```
+- Генератор создаёт mixin (`_$ProfileBloc`), который автоматически резолвит и подставляет зависимости в поля класса.
+- Аннотация `@named` привязывает конкретную реализацию по имени.
+
+Сгенерированный код будет выглядеть вот таким образом:
+
+```dart
+mixin $ProfileBloc {
+	@override
+	void _inject(ProfileBloc instance) {
+		instance.auth = CherryPick.openRootScope().resolve<AuthService>();
+		instance.adminUser = CherryPick.openRootScope().resolve<UserService>(named: 'admin');
+	}	
+}
+```
+
+
+### Как это подключается
+
+```dart
+void main() async {
+  final scope = CherryPick.openRootScope();
+  scope.installModules([
+    $AppModule(),
+  ]);
+  // DI через field injection
+  final bloc = ProfileBloc();
+  runApp(MyApp(bloc: bloc));
+}
+```
+
+---
+
+## Асинхронные зависимости
+
+Для асинхронных провайдеров используйте `toProvideAsync`, а получать их — через `resolveAsync`:
+
+```dart
+bind<RemoteConfig>().toProvideAsync(() async => await RemoteConfig.load());
+
+// Использование:
+final config = await scope.resolveAsync<RemoteConfig>();
+```
+
+---
+
+## Проверка и диагностика
+
+- При неправильных аннотациях или ошибках DI появляется понятное compile-time сообщение.
+- Ошибки биндингов выявляются при генерации кода. Это минимизирует runtime-ошибки и ускоряет разработку.
+
+---
+
+## Использование CherryPick с Flutter: пакет cherrypick_flutter
+
+### Что это такое
+
+[`cherrypick_flutter`](https://pub.dev/packages/cherrypick_flutter) — это пакет интеграции CherryPick DI с Flutter. Он предоставляет удобный виджет-провайдер `CherryPickProvider`, который размещается в вашем дереве виджетов и даёт доступ к root scope DI (и подскоупам) прямо из контекста.
+
+### Ключевые возможности
+
+- **Глобальный доступ к DI Scope:**  
+  Через `CherryPickProvider` вы легко получаете доступ к rootScope и подскоупам из любого места дерева Flutter.
+- **Интеграция с контекстом:**  
+  Используйте `CherryPickProvider.of(context)` для доступа к DI внутри ваших виджетов.
+
+### Пример использования
+
+```dart
+import 'package:flutter/material.dart';
+import 'package:cherrypick_flutter/cherrypick_flutter.dart';
+
+void main() {
+  runApp(
+    CherryPickProvider(
+      child: MyApp(),
+    ),
+  );
+}
+
+class MyApp extends StatelessWidget {
+  @override
+  Widget build(BuildContext context) {
+    final rootScope = CherryPickProvider.of(context).openRootScope();
+
+    return MaterialApp(
+      home: Scaffold(
+        body: Center(
+          child: Text(
+            rootScope.resolve<AppService>().getStatus(),
+          ),
+        ),
+      ),
+    );
+  }
+}
+```
+
+- В этом примере `CherryPickProvider` оборачивает приложение и предоставляет доступ к DI scope через контекст.
+- Вы можете создавать подскоупы, если нужно, например, для экранов или модулей:  
+  `final subScope = CherryPickProvider.of(context).openSubScope(scopeName: "profileFeature");`
+
+---
+## CherryPick подходит не только для Flutter!
+
+Вы можете использовать CherryPick и в Dart CLI, серверных проектах и микросервисах. Все основные возможности доступны и без Flutter.
+
+---
+
+## Пример проекта на CherryPick: полный путь
+
+1. Установите зависимости:
+    ```yaml
+    dependencies:
+      cherrypick: ^1.0.0
+      cherrypick_annotations: ^1.0.0
+
+    dev_dependencies:
+      build_runner: ^2.0.0
+      cherrypick_generator: ^1.0.0
+    ```
+
+2. Описываете свои модули с помощью аннотаций.
+
+3. Для автоматической генерации DI кода используйте:
+    ```shell
+    dart run build_runner build --delete-conflicting-outputs
+    ```
+
+4. Наслаждайтесь современным DI без боли!
+
+---
+
+## Заключение
+
+**CherryPick** — это современное DI-решение для Dart и Flutter, сочетающее лаконичный API и расширенные возможности аннотирования и генерации кода. Гибкость Scopes, параметрические провайдеры, именованные биндинги и field-injection делают его особенно мощным как для небольших, так и для масштабных проектов.
