+# CherryPick Workspace
 
-Experimental development of DI in the Dart language
+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.
 
-- [New Api ENG](/doc/quick_start_en.md)
-- [New Api RU](/doc/quick_start_ru.md)
+---
 
+## Packages Overview
 
-### Features
+- **[`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._
 
-- [x] Scope
-- [x] Sub scope
-- [x] Initialization instance with name
+- **[`cherrypick_annotations`](./cherrypick_annotations)**  
+  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_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._
+
+- **[`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.
+
+---
+
+## 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: ^<latest-version>
+  cherrypick_annotations: ^<latest-version>
+
+dev_dependencies:
+  build_runner: ^<latest>
+  cherrypick_generator: ^<latest-version>
+```
+
+For Flutter projects, add:
+
+```yaml
+dependencies:
+  cherrypick_flutter: ^<latest-version>
+```
+
+### 2. Write a DI Module (with annotations)
+
+```dart
+import 'package:cherrypick_annotations/cherrypick_annotations.dart';
+import 'package:cherrypick/cherrypick.dart';
+
+@module()
+abstract class MyModule extends Module {
+  @singleton()
+  ApiClient apiClient() => ApiClient();
+
+  @provide()
+  DataRepository dataRepo(ApiClient client) => DataRepository(client);
+
+  @provide()
+  String greeting(@params() String name) => 'Hello, $name!';
+}
+```
+
+### 3. Generate the bindings
+
+```sh
+dart run build_runner build
+# or for Flutter:
+flutter pub run build_runner build
+```
+
+The generator will create a `$MyModule` class with binding code.
+
+### 4. Install and Resolve
+
+```dart
+final scope = CherryPick.openRootScope()
+  ..installModules([$MyModule()]);
+
+final repo = scope.resolve<DataRepository>();
+final greeting = scope.resolveWithParams<String>('John'); // 'Hello, John!'
+```
+
+_For Flutter, wrap your app with `CherryPickProvider` for DI scopes in the widget tree:_
+
+```dart
+void main() {
+  runApp(
+    CherryPickProvider(child: MyApp()),
+  );
+}
+```
+
+---
+

+# CherryPick
+
+`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.
+
+## Key Concepts
+
+### Binding
+
+A **Binding** acts as a configuration for how to create or provide a particular dependency. Bindings support:
+
+
+- Direct instance assignment (`toInstance()`, `toInstanceAsync()`)
+- Lazy providers (sync/async functions)
+- Provider functions supporting dynamic parameters
+- Named instances for resolving by string key
+- Optional singleton lifecycle
+
+#### Example
+
+```dart
+// Provide a direct instance
+Binding<String>().toInstance("Hello world");
+
+// Provide an async direct instance
+Binding<String>().toInstanceAsync(Future.value("Hello world"));
+
+// Provide a lazy sync instance using a factory
+Binding<String>().toProvide(() => "Hello world");
+
+// Provide a lazy async instance using a factory
+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
+
+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
+
+```dart
+class AppModule extends Module {
+  @override
+  void builder(Scope currentScope) {
+    bind<ApiClient>().toInstance(ApiClientMock());
+    bind<String>().toProvide(() => "Hello world!");
+  }
+}
+```
+
+### Scope
+
+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.
+
+You typically work with the root scope, but can also create named subscopes as needed.
+
+#### Example
+
+```dart
+// Open the main/root scope
+final rootScope = CherryPick.openRootScope();
+
+// Install a custom module
+rootScope.installModules([AppModule()]);
+
+// Resolve a dependency synchronously
+final str = rootScope.resolve<String>();
+
+// Resolve a dependency asynchronously
+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
+
+Below is a complete example illustrating modules, subscopes, async providers, and dependency resolution.
+
+```dart
+import 'dart:async';
+import 'package:meta/meta.dart';
+import 'package:cherrypick/cherrypick.dart';
+
+class AppModule extends Module {
+  @override
+  void builder(Scope currentScope) {
+    bind<ApiClient>().withName("apiClientMock").toInstance(ApiClientMock());
+    bind<ApiClient>().withName("apiClientImpl").toInstance(ApiClientImpl());
+  }
+}
+
+class FeatureModule extends Module {
+  final bool isMock;
+  FeatureModule({required this.isMock});
+  @override
+  void builder(Scope currentScope) {
+    // Async provider for DataRepository with named dependency selection
+    bind<DataRepository>()
+        .withName("networkRepo")
+        .toProvideAsync(() async {
+          final client = await Future.delayed(
+            Duration(milliseconds: 100),
+            () => currentScope.resolve<ApiClient>(
+              named: isMock ? "apiClientMock" : "apiClientImpl",
+            ),
+          );
+          return NetworkDataRepository(client);
+        })
+        .singleton();
+
+    // Chained async provider for DataBloc
+    bind<DataBloc>().toProvideAsync(
+      () async {
+        final repo = await currentScope.resolveAsync<DataRepository>(
+            named: "networkRepo");
+        return DataBloc(repo);
+      },
+    );
+  }
+}
+
+void main() async {
+  final scope = CherryPick.openRootScope().installModules([AppModule()]);
+  final featureScope = scope.openSubScope("featureScope")
+    ..installModules([FeatureModule(isMock: true)]);
+
+  final dataBloc = await featureScope.resolveAsync<DataBloc>();
+  dataBloc.data.listen(
+    (d) => print('Received data: $d'),
+    onError: (e) => print('Error: $e'),
+    onDone: () => print('DONE'),
+  );
+
+  await dataBloc.fetchData();
+}
+
+class DataBloc {
+  final DataRepository _dataRepository;
+  Stream<String> get data => _dataController.stream;
+  final StreamController<String> _dataController = StreamController.broadcast();
+
+  DataBloc(this._dataRepository);
+
+  Future<void> fetchData() async {
+    try {
+      _dataController.sink.add(await _dataRepository.getData());
+    } catch (e) {
+      _dataController.sink.addError(e);
+    }
+  }
+
+  void dispose() {
+    _dataController.close();
+  }
+}
+
+abstract class DataRepository {
+  Future<String> getData();
+}
+
+class NetworkDataRepository implements DataRepository {
+  final ApiClient _apiClient;
+  final _token = 'token';
+  NetworkDataRepository(this._apiClient);
+
+  @override
+  Future<String> getData() async =>
+      await _apiClient.sendRequest(
+        url: 'www.google.com',
+        token: _token,
+        requestBody: {'type': 'data'},
+      );
+}
+
+abstract class ApiClient {
+  Future sendRequest({@required String? url, String? token, Map? requestBody});
+}
+
+class ApiClientMock implements ApiClient {
+  @override
+  Future sendRequest(
+      {@required String? url, String? token, Map? requestBody}) async {

+  @override
+  Future sendRequest(

+}
+```

+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.

+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing

+[![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.

+/// Annotation to declare a dependency as a singleton.
+///
+/// Use the `@singleton()` annotation on provider methods inside a module
+/// to indicate that only a single instance of this dependency should be
+/// created and shared throughout the application's lifecycle. This is
+/// typically used in dependency injection frameworks or service locators
+/// to guarantee a single shared instance.
+///
+/// Example:
+/// ```dart
+/// @module()
+/// abstract class AppModule extends Module {
+///   @singleton()
+///   Dio dio() => Dio();
+/// }
+/// ```
+///
+/// This will generate code like:
+/// ```dart
+/// final class $AppModule extends AppModule {
+///   @override
+///   void builder(Scope currentScope) {
+///     bind<Dio>().toProvide(() => dio()).singleton();
+///   }
+/// }
+/// ```
+///
+/// RUSSIAN (Русский):
+/// Аннотация для объявления зависимости как синглтона.
+///
+/// Используйте `@singleton()` для методов-провайдеров внутри модуля,
+/// чтобы указать, что соответствующий объект должен быть создан
+/// единожды и использоваться во всём приложении (общий синглтон).
+/// Это характерно для систем внедрения зависимостей и сервис-локаторов,
+/// чтобы гарантировать один общий экземпляр.
+///
+/// Пример:
+/// ```dart
+/// @module()
+/// abstract class AppModule extends Module {
+///   @singleton()
+///   Dio dio() => Dio();
+/// }
+/// ```
+///
+/// Будет сгенерирован следующий код:

+/// final class $AppModule extends AppModule {
+///   @override
+///   void builder(Scope currentScope) {
+///     bind<Dio>().toProvide(() => dio()).singleton();
+///   }
+/// }

+# CherryPick Flutter
+
+`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.
+
+## Installation
+
+Add `cherrypick_flutter` to your `pubspec.yaml`:
+
+```yaml
+dependencies:
+  cherrypick_flutter: ^1.0.0
+```
+
+Run `flutter pub get` to install the package dependencies.
+
+## Usage
+
+### Importing the Package
+
+To begin using `cherrypick_flutter`, import it within your Dart file:
+
+```dart
+import 'package:cherrypick_flutter/cherrypick_flutter.dart';
+```
+
+### Providing State with `CherryPickProvider`
+
+Use `CherryPickProvider` to encase the widget tree section that requires access to the root or specific subscopes:
+
+```dart
+import 'package:flutter/material.dart';
+import 'package:cherrypick_flutter/cherrypick_flutter.dart';
+
+void main() {
+  runApp(
+    CherryPickProvider(
+      child: MyApp(),
+    ),
+  );
+}
+```
+
+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
+
+Access the state provided by `CherryPickProvider` within widget `build` methods using the `of` method:
+
+```dart
+class MyWidget extends StatelessWidget {
+  @override
+  Widget build(BuildContext context) {
+    final CherryPickProvider cherryPick = CherryPickProvider.of(context);
+    final rootScope = cherryPick.openRootScope();
+
+    // Use the rootScope or open a subScope as needed
+    final subScope = cherryPick.openSubScope(scopeName: "exampleScope");
+
+    return Text('Scope accessed!');
+  }
+}
+```
+
+### Updating State
+
+The `CherryPickProvider` setup internally manages state updates. Ensure the `updateShouldNotify` method accurately reflects when the dependents should receive updates. In the provided implementation, it currently does not notify updates automatically.
+
+## Example
+
+Here is an example illustrating how to implement and utilize `CherryPickProvider` within a Flutter application:
+
+```dart
+class MyApp extends StatelessWidget {
+  const MyApp({super.key});
+
+  @override
+  Widget build(BuildContext context) {
+    final rootScope = CherryPickProvider.of(context).openRootScope();
+
+    return MaterialApp.router(
+      routerDelegate: rootScope.resolve<AppRouter>().delegate(),
+      routeInformationParser:
+          rootScope.resolve<AppRouter>().defaultRouteParser(),
+    );
+  }
+}
+```
+
+In this example, `CherryPickProvider` accesses and resolves dependencies using root scope and potentially sub-scopes configured by the application.

+# 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.
+
+---
+
+### Advanced: Customizing Generated File Paths (`build_extensions`)
+
+You can further control the filenames and subdirectory structure of generated files using the `build_extensions` option in `build.yaml`. This is especially useful in large apps for keeping DI artifacts organized under `lib/generated/` or any custom location.
+
+**Example advanced build.yaml:**
+
+```yaml
+targets:
+  $default:
+    builders:
+      cherrypick_generator|inject_generator:
+        options:
+          build_extensions:
+            '^lib/app.dart': ['lib/generated/app.inject.cherrypick.g.dart']
+          output_dir: lib/generated
+        generate_for:
+          - lib/**.dart
+      cherrypick_generator|module_generator:
+        options:
+          build_extensions:
+            '^lib/di/{{}}.dart': ['lib/generated/di/{{}}.module.cherrypick.g.dart']
+          output_dir: lib/generated
+        generate_for:
+          - lib/**.dart
+```
+
+- **output_dir**: Path where all generated files are placed (e.g., `lib/generated`)
+- **build_extensions**: Allows templating of generated filenames and locations. You can use wildcards like `{{}}` to keep directory structure or group related files.
+
+**If you use these options, be sure to update your imports accordingly, for example:**
+
+```dart
+import 'package:your_package/generated/app.inject.cherrypick.g.dart';
+import 'package:your_package/generated/di/app_module.module.cherrypick.g.dart';
+```
+
+### FAQ / Troubleshooting
+
+- If files are missing or located in unexpected directories, double-check your `output_dir` and `build_extensions` configuration.
+- If you change generation paths, always update your imports in the codebase.
+- These options are backward compatible: omitting them preserves pre-existing (side-by-source) output behavior.
+
+---
+
+## 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
+
+### Custom output directory for generated code (output_dir)
+
+You can control the directory where the generated files (`*.inject.cherrypick.g.dart`, `*.module.cherrypick.g.dart`) are placed using the `output_dir` option in your `build.yaml`:
+
+```yaml
+targets:
+  $default:
+    builders:
+      cherrypick_generator|injectBuilder:
+        options:
+          output_dir: lib/generated
+      cherrypick_generator|moduleBuilder:
+        options:
+          output_dir: lib/generated
+```
+
+**If `output_dir` is omitted, generated files are placed next to the original sources (default behavior).**
+
+After running code generation, you will find files like `lib/generated/app.inject.cherrypick.g.dart` and `lib/generated/your_module.module.cherrypick.g.dart`. You can import them as needed from that directory.
+
+- **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.

+# 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.resolveWithParams<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!
+
+---
+
+### Advanced: Customizing Generated Code Location
+
+CherryPick's code generator now supports flexible output configuration via `build.yaml`.
+
+You can control both the output directory (using `output_dir`) and filename templates (using `build_extensions`):
+
+```yaml
+targets:
+  $default:
+    builders:
+      cherrypick_generator|inject_generator:
+        options:
+          build_extensions:
+            '^lib/app.dart': ['lib/generated/app.inject.cherrypick.g.dart']
+          output_dir: lib/generated
+        generate_for:
+          - lib/**.dart
+      cherrypick_generator|module_generator:
+        options:
+          build_extensions:
+            '^lib/di/{{}}.dart': ['lib/generated/di/{{}}.module.cherrypick.g.dart']
+          output_dir: lib/generated
+        generate_for:
+          - lib/**.dart
+```
+
+- **output_dir**: Folder where all generated files will be placed.
+- **build_extensions**: Allows full customization of generated file names and subfolders.
+
+If you use these, be sure to update your imports accordingly, e.g.:
+```dart
+import 'package:your_project/generated/app.inject.cherrypick.g.dart';
+```
+If not specified, generated files will appear next to your source files, as before.
+
+---
+
+---
+
+## 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.resolveWithParams<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!
+
+---
+
+### Продвинутая настройка путей генерации кода
+
+В последних версиях генератора CherryPick добавлена поддержка гибкой настройки директорий и шаблонов имён файлов через `build.yaml`.
+
+Вы можете управлять и папкой назначения (через `output_dir`), и шаблоном имён (через `build_extensions`):
+
+```yaml
+targets:
+  $default:
+    builders:
+      cherrypick_generator|inject_generator:
+        options:
+          build_extensions:
+            '^lib/app.dart': ['lib/generated/app.inject.cherrypick.g.dart']
+          output_dir: lib/generated
+        generate_for:
+          - lib/**.dart
+      cherrypick_generator|module_generator:
+        options:
+          build_extensions:
+            '^lib/di/{{}}.dart': ['lib/generated/di/{{}}.module.cherrypick.g.dart']
+          output_dir: lib/generated
+        generate_for:
+          - lib/**.dart
+```
+
+- **output_dir**: Папка, куда будут складываться все сгенерированные файлы.
+- **build_extensions**: Полный контроль над именами итоговых файлов и подпапками.
+
+Если вы это используете, обязательно обновляйте импорты, например:
+```dart
+import 'package:your_project/generated/app.inject.cherrypick.g.dart';
+```
+Если не задать параметры, файлы будут сгенерированы рядом с исходными — как и раньше.
+
+---
+
+---
+
+## 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.

+**Полный список аннотаций и их предназначение:**
+
+| Аннотация     | Для чего                  | Где применяют                    |
