-
-Benchmarks for performance and features of the cherrypick (core) DI container.
-
-All scenarios use the public API capabilities of cherrypick (scope, module, binding, scoping, and async support).
-
-## Scenarios
-
-- **RegisterAndResolve**: basic registration and resolution of a dependency.
-- **ChainSingleton (A->B->C, singleton)**: dependency chain, all as singletons.
-- **ChainFactory (A->B->C, factory)**: dependency chain with factory bindings (new instance on each request).
-- **NamedResolve (by name)**: resolving a named dependency among multiple implementations.
-- **AsyncChain (A->B->C, async)**: asynchronous dependency chain.
-- **ScopeOverride (child overrides parent)**: overriding a dependency in a child scope over a parent.
-
-## Benchmark results

-| ScopeOverride (child overrides parent)             | 0.3611        |
-
-## How to run
-
-1. Get dependencies:
-   ```shell
-   dart pub get
-   ```
-2. Run the benchmarks:
-   ```shell
-   dart run bin/main.dart
-   ```
-
-A text report with all metrics will be displayed in the console.
-
----
-
-To add your custom scenario — just create a new Dart file and declare a class extending BenchmarkBase or AsyncBenchmarkBase, then add its invocation to main.dart.

-Бенчмарки производительности и функциональности DI-контейнера cherrypick (core).
-
-Все сценарии используют реальные возможности public API cherrypick (scope, module, binding, scoping и асинхронность).
-
-## Сценарии
-
-- **RegisterAndResolve**: базовая операция регистрации и разрешения зависимости.
-- **ChainSingleton (A->B->C, singleton)**: цепочка зависимостей, все singletons.
-- **ChainFactory (A->B->C, factory)**: цепочка зависимостей с factory биндингами, новые объекты на каждый запрос.
-- **NamedResolve (by name)**: разрешение именованной зависимости среди нескольких реализаций.
-- **AsyncChain (A->B->C, async)**: асинхронная цепочка зависимостей.
-- **ScopeOverride (child overrides parent)**: переопределение зависимости в дочернем scope над родительским.

-## Как запускать
-
-1. Получить зависимости:
-   ```shell
-   dart pub get
-   ```
-2. Запустить бенчмарк:
-   ```shell
-   dart run bin/main.dart
-   ```
-
-Будет показан текстовый отчёт по всем метрикам.

+_Benchmark suite for cherrypick DI container, get_it, and other DI solutions._
+
+## Overview
+
+benchmark_di is a flexible benchmarking suite to compare DI containers (like cherrypick and get_it) on synthetic, deep, and real-world dependency scenarios – chains, factories, async, named, override, etc.
+
+**Features:**
+- Universal registration layer and modular scenario setup (works with any DI)
+- Built-in support for [cherrypick](https://github.com/) and [get_it](https://pub.dev/packages/get_it)
+- Clean CLI for matrix runs and output formats (Markdown, CSV, JSON, pretty)
+- Reports metrics: timings, memory (RSS, peak), statistical spreads, and more
+- Extendable via your own DIAdapter or benchmark scenarios
+
+---
+
+## Benchmark Scenarios
+
+- **registerSingleton**: Simple singleton registration/resolution
+- **chainSingleton**: Resolution of long singleton chains (A→B→C...)
+- **chainFactory**: Chain resolution via factories (new instances each time)
+- **asyncChain**: Async chain (with async providers)
+- **named**: Named/qualified resolution (e.g. from multiple implementations)
+- **override**: Resolution and override in subScopes/child adapters
+
+---
+
+## Supported DI
+
+- **cherrypick** (default)
+- **get_it**
+- Easy to add your own DI by creating a DIAdapter
+
+Switch DI with the CLI option: `--di`
+
+---
+
+## How to Run
+
+1. **Install dependencies:**
+   ```shell
+   dart pub get
+   ```
+
+2. **Run all benchmarks (default: all scenarios, 2 warmup, 2 repeats):**
+   ```shell
+   dart run bin/main.dart --benchmark=all --format=markdown
+   ```
+
+3. **For get_it:**
+   ```shell
+   dart run bin/main.dart --di=getit --benchmark=all --format=markdown
+   ```
+
+4. **Show all CLI options:**
+   ```shell
+   dart run bin/main.dart --help
+   ```
+
+### CLI Parameters
+
+- `--di` — DI implementation: `cherrypick` (default) or `getit`
+- `--benchmark, -b` — Scenario: `registerSingleton`, `chainSingleton`, `chainFactory`, `asyncChain`, `named`, `override`, `all`
+- `--chainCount, -c` — Number of parallel chains (e.g. `10,100`)
+- `--nestingDepth, -d` — Chain depth (e.g. `5,10`)
+- `--repeat, -r` — Measurement repeats (default: 2)
+- `--warmup, -w` — Warmup runs (default: 1)
+- `--format, -f` — Output: `pretty`, `csv`, `json`, `markdown`
+- `--help, -h` — Usage
+
+### Run Examples
+
+- **All benchmarks for cherrypick:**
+  ```shell
+  dart run bin/main.dart --di=cherrypick --benchmark=all --format=markdown
+  ```
+
+- **For get_it (all scenarios):**
+  ```shell
+  dart run bin/main.dart --di=getit --benchmark=all --format=markdown
+  ```
+
+- **Specify chains/depth matrix:**
+  ```shell
+  dart run bin/main.dart --benchmark=chainSingleton --chainCount=10,100 --nestingDepth=5,10 --repeat=3 --format=csv
+  ```
+
+---
+
+## Universal DI registration: Adapter-centric approach
+
+Starting from vX.Y.Z, all DI registration scenarios and logic are encapsulated in the adapter itself via the `universalRegistration` method.
+
+### How to use (in Dart code):
+
+```dart
+final di = CherrypickDIAdapter(); // or GetItAdapter(), RiverpodAdapter(), etc
+
+di.setupDependencies(
+  di.universalRegistration(
+    scenario: UniversalScenario.chain,
+    chainCount: 10,
+    nestingDepth: 5,
+    bindingMode: UniversalBindingMode.singletonStrategy,
+  ),
+);
+```
+- There is **no more need to use any global function or switch**: each adapter provides its own type-safe implementation.
+
+### How to add a new scenario or DI:
+- Implement `universalRegistration<S extends Enum>(...)` in your adapter
+- Use your own Enum if you want adapter-specific scenarios!
+- Benchmarks and CLI become automatically extensible for custom DI and scenarios.
+
+### CLI usage (runs all universal scenarios for Cherrypick, GetIt, Riverpod):
+
+```
+dart run bin/main.dart --di=cherrypick --benchmark=all
+dart run bin/main.dart --di=getit --benchmark=all
+dart run bin/main.dart --di=riverpod --benchmark=all
+```
+
+See the `benchmark_di/lib/di_adapters/` folder for ready-to-use adapters.
+
+---
+## Advantages
+
+- **Type-safe:** Zero dynamic/object usage in DI flows.
+- **Extensible:** New scenarios are just new Enum values and a method extension.
+- **No global registration logic:** All DI-related logic is where it belongs: in the adapter.
+
+=======
+## How to Add Your Own DI
+
+1. Implement a class extending `DIAdapter` (`lib/di_adapters/your_adapter.dart`)
+2. Implement the `universalRegistration<S extends Enum>(...)` method directly in your adapter for type-safe and scenario-specific registration
+3. Register your adapter in CLI (see `cli/benchmark_cli.dart`)
+4. No global function needed — all logic is within the adapter!

+
+_Бенчмаркинговый набор для cherrypick, get_it и других DI-контейнеров._
+
+## Общее описание
+
+benchmark_di — это современный фреймворк для измерения производительности DI-контейнеров (как cherrypick, так и get_it) на синтетических, сложных и реальных сценариях: цепочки зависимостей, factory, async, именованные биндинги, override и пр.
+
+**Возможности:**
+- Универсальный слой регистрации сценариев (работает с любым DI)
+- Готовая поддержка [cherrypick](https://github.com/) и [get_it](https://pub.dev/packages/get_it)
+- Удобный CLI для запусков по матрице значений параметров и различных форматов вывода (Markdown, CSV, JSON, pretty)
+- Сбор и вывод метрик: время, память (RSS, peak), статистика (среднее, медиана, stddev, min/max)
+- Легко расширять — создавайте свой DIAdapter и новые сценарии
+
+---
+
+## Сценарии бенчмарков
+
+- **registerSingleton**: Регистрация и резолвинг singleton
+- **chainSingleton**: Разрешение длинных singleton-цепочек (A→B→C…)
+- **chainFactory**: То же, но с factory (каждый раз — новый объект)
+- **asyncChain**: Асинхронная цепочка (async factory/provider)
+- **named**: Разрешение по имени (например, из нескольких реализаций)
+- **override**: Переопределение зависимостей в subScope
+
+---
+
+## Поддерживаемые DI-контейнеры
+
+- **cherrypick** (по умолчанию)
+- **get_it**
+- Легко добавить свой DI через DIAdapter
+
+Меняется одной CLI-опцией: `--di`
+
+---
+
+## Как запустить
+
+1. **Установить зависимости:**
+   ```shell
+   dart pub get
+   ```
+
+2. **Запустить все бенчмарки (по умолчанию: все сценарии, 2 прогрева, 2 замера):**
+   ```shell
+   dart run bin/main.dart --benchmark=all --format=markdown
+   ```
+
+3. **Для get_it:**
+   ```shell
+   dart run bin/main.dart --di=getit --benchmark=all --format=markdown
+   ```
+
+4. **Показать все опции CLI:**
+   ```shell
+   dart run bin/main.dart --help
+   ```
+
+### Параметры CLI
+
+- `--di` — Какой DI использовать: `cherrypick` (по умолчанию) или `getit`
+- `--benchmark, -b` — Сценарий: `registerSingleton`, `chainSingleton`, `chainFactory`, `asyncChain`, `named`, `override`, `all`
+- `--chainCount, -c` — Сколько параллельных цепочек (например, `10,100`)
+- `--nestingDepth, -d` — Глубина цепочки (например, `5,10`)
+- `--repeat, -r` — Повторов замера (по умолчанию 2)
+- `--warmup, -w` — Прогревочных запусков (по умолчанию 1)
+- `--format, -f` — Формат отчёта: `pretty`, `csv`, `json`, `markdown`
+- `--help, -h` — Справка
+
+### Примеры запуска
+
+- **Все бенчмарки для cherrypick:**
+  ```shell
+  dart run bin/main.dart --di=cherrypick --benchmark=all --format=markdown
+  ```
+
+- **Для get_it (все сценарии):**
+  ```shell
+  dart run bin/main.dart --di=getit --benchmark=all --format=markdown
+  ```
+
+- **Запуск по матрице параметров:**
+  ```shell
+  dart run bin/main.dart --benchmark=chainSingleton --chainCount=10,100 --nestingDepth=5,10 --repeat=3 --format=csv
+  ```
+
+---
+
+## Универсальная регистрация зависимостей: теперь через adapter
+
+В версии X.Y.Z вся логика сценариев регистрации DI-инфраструктуры локализована в adapter через метод `universalRegistration`.
+
+### Использование в Dart:
+
+```dart
+final di = CherrypickDIAdapter(); // или GetItAdapter(), RiverpodAdapter() и т.д.
+
+di.setupDependencies(
+  di.universalRegistration(
+    scenario: UniversalScenario.chain,
+    chainCount: 10,
+    nestingDepth: 5,
+    bindingMode: UniversalBindingMode.singletonStrategy,
+  ),
+);
+```
+- **Теперь нет необходимости вызывать глобальные функции или switch-case по типу DI!** Каждый adapter сам предоставляет типобезопасную функцию регистрации.
+
+### Как добавить новый сценарий или DI:
+
+- Реализуйте метод `universalRegistration<S extends Enum>(...)` в своём adapter.
+- Можно использовать как UniversalScenario, так и собственные enum-сценарии!
+- Бенчмарки CLI автоматически расширяются под ваш DI и ваши сценарии, если реализован метод-расширение.
+
+### Запуск CLI (все сценарии DI Cherrypick, GetIt, Riverpod):
+
+```
+dart run bin/main.dart --di=cherrypick --benchmark=all
+dart run bin/main.dart --di=getit --benchmark=all
+dart run bin/main.dart --di=riverpod --benchmark=all
+```
+
+Смотрите примеры готовых adapters в `benchmark_di/lib/di_adapters/`.
+
+## Преимущества
+
+- **Type-safe:** Исключено использование dynamic/object в стороне DI.
+- **Масштабируемость:** Новый сценарий — просто enum + метод в adapter.
+- **Вся логика регистрации теперь только в adapter:** Добавление или изменение не затрагивает глобальные функции.

+
+## Analysis
+
+- **get_it** remains the clear leader for both speed and memory usage (lowest latency across most scenarios; excellent memory efficiency even on deep chains).
+- **kiwi** shows the lowest memory footprint in chainSingleton, but is unavailable for async chains.
+- **yx_scope** demonstrates highly stable performance for both sync and async chains, often at the cost of higher memory usage, especially in the register/override scenarios.
+- **cherrypick** comfortably beats riverpod, but is outperformed by get_it/kiwi/yx_scope, especially on async and heavy nested chains. It uses a bit less memory than yx_scope and kiwi, but can spike in memory/latency for override.
+- **riverpod** is unsuitable for deep or async chains—latency and memory usage grow rapidly.
+- **Peak memory (RSS):** usually around 320–340 MB for all DI; riverpod/kiwi occasionally drops below 300MB. named/factory scenarios use much less.
+- **Stability:** yx_scope and get_it have the lowest latency spikes; cherrypick can show peaks on override/async; riverpod is least stable on async (stddev/mean much worse).
+
+### Recommendations
+
+- **get_it** (and often **kiwi**, if you don't need async): best for ultra-fast deep graphs and minimum peak memory.
+- **yx_scope**: best blend of performance and async stability; perfect for production mixed DI.
+- **cherrypick**: great for modular/testable architectures, unless absolute peak is needed; lower memory than yx_scope in some scenarios.
+- **riverpod**: only for shallow DI or UI wiring in Flutter.

+
+---
+
+## Краткий анализ и рекомендации
+
+- **get_it** — абсолютный лидер по скорости и памяти на всех графах (минимальная задержка, небольшой peak RSS в любых цепочках).
+- **kiwi** — минимальное потребление памяти в chainSingleton/Factory, но не для асинхронности.
+- **yx_scope** — очень ровная производительность даже на сложных async/sync-цепях, иногда с пиком в памяти на override/register, но задержки всегда минимальны.
+- **cherrypick** — стабильнее riverpod, но ощутимо уступает top-3 по латентности на длинных/async-графах; по памяти лучше yx_scope для override/named.
+- **riverpod** — непригоден для глубоких/async-графов: память и время растут очень сильно.
+- **Пиковое потребление памяти**: большинство DI держится в районе 320–340 Мб (большие цепи), на мелких named/factory — крайне мало.
+- **Стабильность**: yx_scope и get_it показывают наименьшие скачки времени; у cherrypick иногда всплески на override/async, у riverpod — на async графе stddev почти равен mean!
+
+### Рекомендации
+- Используйте **get_it** (или **kiwi**, если не нужен async) для максимальной производительности и минимального пикового использования памяти.
+- **yx_scope** — идеально для production-графов с миксом sync/async.
+- **cherrypick** — хорошо для модульных и тестируемых приложений, если не требуется абсолютная “микросекундная” производительность.
+- **riverpod** — только если граф плоский или нужно DI только для UI во Flutter.

+
+## Installation
+
+Add to your `pubspec.yaml`:
+
+```yaml
+dependencies:
+  cherrypick: ^<latest_version>
+````
+
+Then run:
+
+```shell
+dart pub get
+```
+
+---
+
+## Getting Started
+
+Here is a minimal example that registers and resolves a dependency:
+
+```dart
+import 'package:cherrypick/cherrypick.dart';
+
+class AppModule extends Module {
+  @override
+  void builder(Scope currentScope) {
+    bind<ApiClient>().toInstance(ApiClientMock());
+    bind<String>().toProvide(() => "Hello, CherryPick!");
+  }
+}
+
+final rootScope = CherryPick.openRootScope();
+rootScope.installModules([AppModule()]);
+
+final greeting = rootScope.resolve<String>();
+print(greeting); // prints: Hello, CherryPick!
+
+await CherryPick.closeRootScope();
+```
+
+---
+
+## Core 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
+* 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");
+void builder(Scope scope) {
+  // Provide a direct instance

+> ⚠️ **Important note about using `toInstance` in Module `builder`:**
+>
+> If you register a chain of dependencies via `toInstance` inside a Module's `builder`, **do not** call `scope.resolve<T>()` for types that are also being registered in the same builder — at the moment they are registered.
+>
+> CherryPick initializes all bindings in the builder sequentially. Dependencies registered earlier are not yet available to `resolve` within the same builder execution. Trying to resolve just-registered types will result in an error (`Can't resolve dependency ...`).
+>
+> **How to do it right:**  
+> Manually construct the full dependency chain before calling `toInstance`:
+>
+> ```dart
+> void builder(Scope scope) {
+>   final a = A();
+>   final b = B(a);
+>   final c = C(b);
+>   bind<A>().toInstance(a);
+>   bind<B>().toInstance(b);
+>   bind<C>().toInstance(c);
+> }
+> ```
+>
+> **Wrong:**
+> ```dart
+> void builder(Scope scope) {
+>   bind<A>().toInstance(A());
+>   // Error! At this point, A is not registered yet.
+>   bind<B>().toInstance(B(scope.resolve<A>()));
+> }
+> ```
+>
+> **Wrong:**
+> ```dart
+> void builder(Scope scope) {
+>   bind<A>().toProvide(() => A());
+>   // Error! At this point, A is not registered yet.
+>   bind<B>().toInstance(B(scope.resolve<A>()));
+> }
+> ```
+>
+> **Note:** This limitation applies **only** to `toInstance`. With `toProvide`/`toProvideAsync` and similar providers, you can safely use `scope.resolve<T>()` inside the builder.
+
+
+  > ⚠️ **Special note regarding `.singleton()` with `toProvideWithParams()` / `toProvideAsyncWithParams()`:**
+  >
+  > If you declare a binding using `.toProvideWithParams(...)` (or its async variant) and then chain `.singleton()`, only the **very first** `resolve<T>(params: ...)` will use its parameters; every subsequent call (regardless of params) will return the same (cached) instance.
+  >
+  > **Example:**
+  > ```dart
+  > bind<Service>().toProvideWithParams((params) => Service(params)).singleton();
+  > final a = scope.resolve<Service>(params: 1); // creates Service(1)
+  > final b = scope.resolve<Service>(params: 2); // returns Service(1)
+  > print(identical(a, b)); // true
+  > ```
+  >
+  > Use this pattern only when you want a “master” singleton. If you expect a new instance per params, **do not** use `.singleton()` on parameterized providers.
+
+
+> ℹ️ **Note about `.singleton()` and `.toInstance()`:**
+>
+> Calling `.singleton()` after `.toInstance()` does **not** change the binding’s behavior: the object passed with `toInstance()` is already a single, constant instance that will be always returned for every resolve.
+>
+> It is not necessary to use `.singleton()` with an existing object—this call has no effect.
+>
+> `.singleton()` is only meaningful with providers (such as `toProvide`/`toProvideAsync`), to ensure only one instance is created by the factory.

 ```
 
-#### Working with Subscopes
+---
 
+### Disposable
+
+CherryPick can automatically clean up any dependency that implements the `Disposable` interface. This makes resource management (for controllers, streams, sockets, files, etc.) easy and reliable—especially when scopes or the app are shut down.
+
+If you bind an object implementing `Disposable` as a singleton or provide it via the DI container, CherryPick will call its `dispose()` method when the scope is closed or cleaned up.
+
+#### Key Points
+- Supports both synchronous and asynchronous cleanup (dispose may return `void` or `Future`).
+- All `Disposable` instances from the current scope and subscopes will be disposed in the correct order.
+- Prevents resource leaks and enforces robust cleanup.
+- No manual wiring needed once your class implements `Disposable`.
+
+#### Minimal Sync Example
 ```dart
-// Open a named child scope (e.g., for a feature/module)
-final subScope = rootScope.openSubScope('featureScope')
-  ..installModules([FeatureModule()]);
+class CacheManager implements Disposable {
+  void dispose() {
+    cache.clear();
+    print('CacheManager disposed!');
+  }
+}
 
-// Resolve from subScope, with fallback to parents if missing
-final dataBloc = await subScope.resolveAsync<DataBloc>();
+final scope = CherryPick.openRootScope();
+scope.installModules([
+  Module((bind) => bind<CacheManager>().toProvide(() => CacheManager()).singleton()),
+]);
+
+// ...later
+await CherryPick.closeRootScope(); // prints: CacheManager disposed!
 ```
 
-### Dependency Lookup API
+#### Async Example
+```dart
+class MyServiceWithSocket implements Disposable {
+  @override
+  Future<void> dispose() async {
+    await socket.close();
+    print('Socket closed!');
+  }
+}
+
+scope.installModules([
+  Module((bind) => bind<MyServiceWithSocket>().toProvide(() => MyServiceWithSocket()).singleton()),
+]);
+
+await CherryPick.closeRootScope(); // awaits async disposal
+```
+
+**Tip:** Always call `await CherryPick.closeRootScope()` or `await scope.closeSubScope(key)` in your shutdown/teardown logic to ensure all resources are released automatically.

+
+## Using Annotations & Code Generation
+
+CherryPick provides best-in-class developer ergonomics and type safety through **Dart annotations** and code generation. This lets you dramatically reduce boilerplate: simply annotate your classes, fields, and modules, run the code generator, and enjoy auto-wired dependency injection!
+
+### How It Works
+
+1. **Annotate** your services, providers, and fields using `cherrypick_annotations`.
+2. **Generate** code using `cherrypick_generator` with `build_runner`.
+3. **Use** generated modules and mixins for fully automated DI (dependency injection).
+
+---
+
+### Supported Annotations
+
+| Annotation        | Target         | Description                                                                    |
+|-------------------|---------------|--------------------------------------------------------------------------------|
+| `@injectable()`   | class         | Enables automatic field injection for this class (mixin will be generated)      |
+| `@inject()`       | field         | Field will be injected using DI (works with @injectable classes)                |
+| `@module()`       | class         | Declares a DI module; its methods can provide services/providers                |
+| `@provide`        | method        | Registers as a DI provider method (may have dependencies as parameters)         |
+| `@instance`       | method/class  | Registers an instance (new object on each resolution, i.e. factory)             |
+| `@singleton`      | method/class  | Registers as a singleton (one instance per scope)                               |
+| `@named`          | field/param   | Use named instance (bind/resolve by name or apply to field/param)               |
+| `@scope`          | field/param   | Inject or resolve from a specific named scope                                   |
+| `@params`         | param         | Marks method parameter as filled by user-supplied runtime params at resolution  |
+
+You can easily **combine** these annotations for advanced scenarios!
+
+---
+
+### Field Injection Example
+
+```dart
+import 'package:cherrypick_annotations/cherrypick_annotations.dart';
+
+@injectable()
+class ProfilePage with _\$ProfilePage {
+  @inject()
+  late final AuthService auth;
+
+  @inject()
+  @scope('profile')
+  late final ProfileManager manager;
+
+  @inject()
+  @named('admin')
+  late final UserService adminUserService;
+}
+```
+
+- After running build_runner, the mixin `_ProfilePage` will be generated for field injection.
+- Call `myProfilePage.injectFields();` or use the mixin's auto-inject feature, and all dependencies will be set up for you.
+
+---
+
+### Module and Provider Example
+
+```dart
+@module()
+abstract class AppModule {
+  @singleton
+  AuthService provideAuth(Api api) => AuthService(api);
+
+  @named('logging')
+  @provide
+  Future<Logger> provideLogger(@params Map<String, dynamic> args) async => ...;
+}
+```
+
+- Mark class as `@module`, write provider methods.
+- Use `@singleton`, `@named`, `@provide`, `@params` to control lifecycle, key names, and parameters.
+- The generator will produce a class like `$AppModule` with the proper DI bindings.
+
+---
+
+### Usage Steps
+
+1. **Add to your pubspec.yaml**:
+
+   ```yaml
+   dependencies:
+     cherrypick: any
+     cherrypick_annotations: any
+
+   dev_dependencies:
+     cherrypick_generator: any
+     build_runner: any
+   ```
+
+2. **Annotate** your classes and modules as above.
+
+3. **Run code generation:**
+
+   ```shell
+   dart run build_runner build --delete-conflicting-outputs
+   # or in Flutter:
+   flutter pub run build_runner build --delete-conflicting-outputs
+   ```
+
+4. **Register modules and use auto-injection:**
+
+   ```dart
+   final scope = CherryPick.openRootScope()
+     ..installModules([$AppModule()]);
+
+   final profile = ProfilePage();
+   profile.injectFields(); // injects all @inject fields
+   ```
+
+---
+
+### Advanced: Parameters, Named Instances, and Scopes
+
+- Use `@named` for key-based multi-implementation injection.
+- Use `@scope` when dependencies live in a non-root scope.
+- Use `@params` for runtime arguments passed during resolution.
+
+---
+
+### Troubleshooting & Tips
+
+- After modifying DI-related code, always re-run `build_runner`.
+- Do not manually edit `.g.dart` files—let the generator manage them.
+- Errors in annotation usage (e.g., using `@singleton` on wrong target) are shown at build time.

+
+## Advanced Features
+
+### Hierarchical Subscopes
+
+CherryPick supports a hierarchical structure of scopes, allowing you to create complex and modular dependency graphs for advanced application architectures. Each subscope inherits from its parent, enabling context-specific overrides while still allowing access to global or shared services.
+
+#### Key Points
+
+- **Subscopes** are child scopes that can be opened from any existing scope (including the root).
+- Dependencies registered in a subscope override those from parent scopes when resolved.
+- If a dependency is not found in the current subscope, the resolution process automatically searches parent scopes up the hierarchy.
+- Subscopes can have their own modules, lifetime, and disposable objects.
+- You can nest subscopes to any depth, modeling features, flows, or components independently.
+
+#### Example
+
+```dart
+final rootScope = CherryPick.openRootScope();
+rootScope.installModules([AppModule()]);
+
+// Open a hierarchical subscope for a feature or page
+final userFeatureScope = rootScope.openSubScope('userFeature');
+userFeatureScope.installModules([UserFeatureModule()]);
+
+// Dependencies defined in UserFeatureModule will take precedence
+final userService = userFeatureScope.resolve<UserService>();
+
+// If not found in the subscope, lookup continues in the parent (rootScope)
+final sharedService = userFeatureScope.resolve<SharedService>();
+
+// You can nest subscopes
+final dialogScope = userFeatureScope.openSubScope('dialog');
+dialogScope.installModules([DialogModule()]);
+final dialogManager = dialogScope.resolve<DialogManager>();
+```
+
+#### Use Cases
+
+- Isolate feature modules, flows, or screens with their own dependencies.
+- Provide and override services for specific navigation stacks or platform-specific branches.
+- Manage the lifetime and disposal of groups of dependencies independently (e.g., per-user, per-session, per-component).
+
+**Tip:** Always close subscopes when they are no longer needed to release resources and trigger cleanup of Disposable dependencies.
+
+---
+
+### Logging
+
+CherryPick lets you log all dependency injection (DI) events and errors using a flexible observer mechanism.
+
+#### Custom Observers
+
+You can pass any implementation of `CherryPickObserver` to your root scope or any sub-scope.
+This allows centralized and extensible logging, which you can direct to print, files, visualization frameworks, external loggers, or systems like [Talker](https://pub.dev/packages/talker).
+
+##### Example: Printing All Events
+
+```dart
+import 'package:cherrypick/cherrypick.dart';
+
+void main() {
+  // Use the built-in PrintCherryPickObserver for console logs
+  final observer = PrintCherryPickObserver();
+  final scope = CherryPick.openRootScope(observer: observer);
+  // All DI actions and errors will now be printed!
+}
+```
+
+##### Example: Advanced Logging with Talker
+
+For richer logging, analytics, or UI overlays, use an advanced observer such as [talker_cherrypick_logger](../talker_cherrypick_logger):
+
+```dart
+import 'package:cherrypick/cherrypick.dart';
+import 'package:talker/talker.dart';
+import 'package:talker_cherrypick_logger/talker_cherrypick_logger.dart';
+
+void main() {
+  final talker = Talker();
+  final observer = TalkerCherryPickObserver(talker);
+  CherryPick.openRootScope(observer: observer);
+  // All container events go to the Talker log system!
+}
+```
+
+#### Default Behavior
+
+- By default, logging is silent (`SilentCherryPickObserver`) for production, with no output unless you supply an observer.
+- You can configure observers **per scope** for isolated, test-specific, or feature-specific logging.
+
+#### Observer Capabilities
+
+Events you can observe and log:
+- Dependency registration
+- Instance requests, creations, disposals
+- Module installs/removals
+- Scope opening/closing
+- Cache hits/misses
+- Cycle detection
+- Diagnostics, warnings, errors
+
+Just implement or extend `CherryPickObserver` and direct messages anywhere you want!
+
+#### When to Use
+
+- Enable verbose logging and debugging in development or test builds.
+- Route logs to your main log system or analytics.
+- Hook into DI lifecycle for profiling or monitoring.

+
+### Circular Dependency Detection
+
+CherryPick can detect circular dependencies in your DI configuration, helping you avoid infinite loops and hard-to-debug errors.
+
+**How to use:**
+
+#### 1. Enable Cycle Detection for Development
+
+**Local detection (within one scope):**
+```dart
+final scope = CherryPick.openSafeRootScope(); // Local detection enabled by default
+// or, for an existing scope:
+scope.enableCycleDetection();
+```
+
+**Global detection (across all scopes):**
+```dart
+CherryPick.enableGlobalCrossScopeCycleDetection();
+final rootScope = CherryPick.openGlobalSafeRootScope();
+```
+
+#### 2. Error Example
+
+If you declare mutually dependent services:
+```dart
+class A { A(B b); }
+class B { B(A a); }
+
+scope.installModules([
+  Module((bind) {
+    bind<A>().to((s) => A(s.resolve<B>()));
+    bind<B>().to((s) => B(s.resolve<A>()));
+  }),
+]);
+
+scope.resolve<A>(); // Throws CircularDependencyException
+```
+
+#### 3. Typical Usage Pattern
+
+- **Always enable detection** in debug and test environments for maximum safety.
+- **Disable detection** in production for performance (after code is tested).
+
+```dart
+import 'package:flutter/foundation.dart';
+
+void main() {
+  if (kDebugMode) {
+    CherryPick.enableGlobalCycleDetection();
+    CherryPick.enableGlobalCrossScopeCycleDetection();
+  }
+  runApp(MyApp());
+}
+```
+
+#### 4. Handling and Debugging Errors
+
+On detection, `CircularDependencyException` is thrown with a readable dependency chain:
+```dart
+try {
+  scope.resolve<MyService>();
+} on CircularDependencyException catch (e) {
+  print('Dependency chain: ${e.dependencyChain}');
+}
+```
+
+**More details:** See [cycle_detection.en.md](doc/cycle_detection.en.md)
+
+---
+
+### Performance Improvements
+
+> **Performance Note:**  
+> **Starting from version 3.0.0**, CherryPick uses a Map-based resolver index for dependency lookup. This means calls to `resolve<T>()` and related methods are now O(1) operations, regardless of the number of modules or bindings in your scope. Previously, the library had to iterate over all modules and bindings to locate the requested dependency, which could impact performance as your project grew.
+>
+> This optimization is internal and does not change any library APIs or usage patterns, but it significantly improves resolution speed in larger applications.

+## FAQ
 
-## Quick Guide: Circular Dependency Detection
+### Q: Do I need to use `await` with CherryPick.closeRootScope(), CherryPick.closeScope(), or scope.dispose() if I have no Disposable services?
 
-CherryPick can detect circular dependencies in your DI configuration, helping you avoid infinite loops and hard-to-debug errors.
+**A:**  
+Yes! Even if none of your services currently implement `Disposable`, always use `await` when closing scopes. If you later add resource cleanup (by implementing `dispose()`), CherryPick will handle it automatically without you needing to change your scope cleanup code. This ensures resource management is future-proof, robust, and covers all application scenarios.

+/// An interface for resources that require explicit cleanup, used by the CherryPick dependency injection container.
+///
+/// If an object implements [Disposable], the CherryPick DI container will automatically call [dispose]
+/// when the corresponding scope is cleaned up. Use [Disposable] for closing streams, files, controllers, services, etc.
+/// Both synchronous and asynchronous cleanup is supported:
+/// - For sync disposables, implement [dispose] as a `void` or simply return nothing.
+/// - For async disposables, implement [dispose] returning a [Future].
+///
+/// Example: Synchronous Disposable
+/// ```dart
+/// class MyLogger implements Disposable {
+///   void dispose() {
+///     print('Logger closed!');
+///   }
+/// }
+/// ```
+///
+/// Example: Asynchronous Disposable
+/// ```dart
+/// class MyConnection implements Disposable {
+///   @override
+///   Future<void> dispose() async {
+///     await connection.close();
+///   }
+/// }
+/// ```
+///
+/// Usage with CherryPick DI Module
+/// ```dart
+/// final scope = openRootScope();
+/// scope.installModules([
+///   Module((b) {
+///     b.bind<MyLogger>((_) => MyLogger());
+///     b.bindAsync<MyConnection>((_) async => MyConnection());
+///   }),
+/// ]);
+/// // ...
+/// await scope.close(); // will automatically call dispose on all Disposables
+/// ```
+///
+/// This pattern ensures that all resources are released safely and automatically when the scope is destroyed.
+abstract class Disposable {
+  /// Releases all resources held by this object.
+  ///
+  /// Implement cleanup logic (closing streams, sockets, files, etc.) within this method.

-Scope openRootScope() => Scope(null);

+/// Represents a DI scope (container) for modules, subscopes,
+/// and dependency resolution (sync/async) in CherryPick.
+///
+/// Scopes provide hierarchical DI: you can resolve dependencies from parents,
+/// override or isolate modules, and manage scope-specific singletons.
+///
+/// Each scope:
+/// - Can install modules ([installModules]) that define [Binding]s
+/// - Supports parent-child scope tree (see [openSubScope])
+/// - Can resolve dependencies synchronously ([resolve]) or asynchronously ([resolveAsync])
+/// - Cleans up resources for [Disposable] objects (see [dispose])
+/// - Detects dependency cycles (local and global, if enabled)
+///
+/// Example usage:
+/// ```dart
+/// final rootScope = CherryPick.openRootScope();
+/// rootScope.installModules([AppModule()]);
+///
+/// // Synchronous resolution:
+/// final auth = rootScope.resolve<AuthService>();
+///
+/// // Asynchronous resolution:
+/// final db = await rootScope.resolveAsync<Database>();
+///
+/// // Open a child scope (for a feature, page, or test):
+/// final userScope = rootScope.openSubScope('user');
+/// userScope.installModules([UserModule()]);
+///
+/// // Proper resource cleanup (calls dispose() on tracked objects)
+/// await CherryPick.closeRootScope();

-/// Annotation to assign a name or identifier to a class, method, or other element.
+import 'package:meta/meta.dart';
+
+/// Assigns a name or key identifier to a class, field, factory method or parameter
+/// for use in multi-registration scenarios (named dependencies) in CherryPick DI.
 ///
-/// The `@named('value')` annotation allows you to specify a string name
-/// for a dependency, factory, or injectable. This is useful for distinguishing
-/// between multiple registrations of the same type in dependency injection,

+/// Use `@named('key')` to distinguish between multiple bindings/implementations
+/// of the same type—when registering and when injecting dependencies.
 ///
-/// Example:
+/// You can use `@named`:
+/// - On provider/factory methods in a module
+/// - On fields with `@inject()` to receive a named instance
+/// - On function parameters (for method/constructor injection)
+///
+/// ### Example: On Provider Method
 /// ```dart
 /// @module()
-/// abstract class AppModule extends Module {
-///   @named('dio')
-///   Dio dio() => Dio();
+/// abstract class AppModule {
+///   @named('main')
+///   ApiClient apiClient() => ApiClient();
+///
+///   @named('mock')
+///   ApiClient mockApi() => MockApiClient();
 /// }
 /// ```
 ///
-/// This will generate:

 /// ```dart
-/// final class $AppModule extends AppModule {

 # 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.

+/// CherryPick code generation library: entry point for build_runner DI codegen.
+///
+/// This library exports generators for CherryPick dependency injection:
+/// - [ModuleGenerator]: Generates DI module classes for all `@module()`-annotated classes.
+/// - [InjectGenerator]: Generates field-injection mixins for classes annotated with `@injectable()`.
+///
+/// These generators are hooked into [build_runner] and cherrypick_generator's builder configuration.
+/// Normally you do not import this directly; instead, add cherrypick_generator
+/// as a dev_dependency and run `dart run build_runner build`.
+///
+/// Example usage in `build.yaml` or your project's workflow:
+/// ```yaml
+/// targets:
+///   $default:
+///     builders:
+///       cherrypick_generator|cherrypick_generator:
+///         generate_for:
+///           - lib/**.dart

+/// ### Example usage in a project:
 ///
-/// Для Future<T> полей вызывается .resolveAsync<T>(),
-/// для остальных — .resolve<T>(). Поддерживаются scope и named qualifier.
+/// ```dart
+/// import 'package:cherrypick_annotations/cherrypick_annotations.dart';

+///
+///   @inject()
+///   Future<Analytics>? analytics;
+/// }
+/// ```
+///
+/// After running build_runner, this mixin will be auto-generated:
+///
+/// ```dart
+/// mixin _$MyScreen {
+///   void _inject(MyScreen instance) {
+///     instance.logger = CherryPick.openRootScope().resolve<Logger>();

+///   }
+/// }
+/// ```
+///
+/// You may use the mixin (e.g., `myScreen._inject(myScreen)`) or expose your own public helper for instance field injection.
+///
+/// **Supported scenarios:**
+/// - Ordinary injectable fields: `resolve<T>()`.
+/// - Named qualifiers: `resolve<T>(named: ...)`.
+/// - Scoping: `CherryPick.openScope(scopeName: ...).resolve<T>()`.
+/// - Nullable/incomplete fields: `tryResolve`/`tryResolveAsync`.
