+# 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!
+
+---
+
+## 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!

+
+## 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                    |
+| ------------- | ------------------------- | -------------------------------- |
+| `@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                 |
