# benchmark_di
|
||||
|
||||
_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!
|
||||
|
||||
---
|
||||
## 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.

# benchmark_di
|
||||
|
||||
_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** is the absolute leader in all scenarios, especially under deep/nested chains and async.
|
||||
- **cherrypick** is highly competitive and much faster than riverpod on any complex graph.
|
||||
- **riverpod** is only suitable for small/simple DI graphs due to major slowdowns with depth, async, or override.
|
||||
|
||||
### Recommendations
|
||||
- Use **get_it** for performance-critical and deeply nested graphs.
|
||||
- Use **cherrypick** for scalable/testable apps if a small speed loss is acceptable.
|
||||
- Use **riverpod** only if you rely on Flutter integration and your DI chains are simple.

# Сравнительный отчет DI-бенчмарка: cherrypick vs get_it vs riverpod
|
||||
|
||||
## Описание сценариев
|
||||
|
||||
1. **RegisterSingleton** — регистрация и получение объекта-синглтона (базовая скорость DI).
|
||||
2. **ChainSingleton** — цепочка зависимостей A → B → ... → N (singleton). Глубокий singleton-резолвинг.
|
||||
3. **ChainFactory** — все элементы цепочки — фабрики. Stateless построение графа.
|
||||
4. **AsyncChain** — асинхронная цепочка (async factory). Тестирует async/await граф.
|
||||
5. **Named** — регистрация двух биндингов с именами, разрешение по имени.
|
||||
6. **Override** — регистрация биндинга/цепочки в дочернем scope. Проверка override/scoping.

## Краткий анализ и рекомендации
|
||||
|
||||
- **get_it** всегда лидер, особенно на глубине/асинхронных графах.
|
||||
- **cherrypick** заметно быстрее riverpod на сложных сценариях, опережая его в разы.
|
||||
- **riverpod** подходит только для простых/небольших графов — при росте глубины или async/override резко проигрывает по скорости.
|
||||
|
||||
### Рекомендации
|
||||
- Используйте **get_it** для критичных к скорости приложений/сложных графов зависимостей.
|
||||
- Выбирайте **cherrypick** для масштабируемых, тестируемых архитектур, если микросекундная разница не критична.
|
||||
- **riverpod** уместен только для реактивного UI или простых графов DI.

## 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();
|
||||
```

## 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
|
||||
|
||||
- Direct instance assignment (`toInstance()`, `toInstanceAsync()`)
|

||||
- Named instances for resolving by string key
|
||||
- Optional singleton lifecycle

// Close the root scope once done
|

CherryPick.closeRootScope();
|
||||
```
|
||||
|
||||
---
|
||||
#### 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
|
||||
class CacheManager implements Disposable {
|
||||
void dispose() {
|
||||
cache.clear();
|
||||
print('CacheManager disposed!');
|
||||
}
|
||||
}
|
||||
// Open a named child scope (e.g., for a feature/module)
|
||||
final subScope = rootScope.openSubScope('featureScope')
|
||||
..installModules([FeatureModule()]);
|
||||
|
||||
final scope = CherryPick.openRootScope();
|
||||
scope.installModules([
|
||||
Module((bind) => bind<CacheManager>().toProvide(() => CacheManager()).singleton()),
|
||||
]);
|
||||
|
||||
// ...later
|
||||
await CherryPick.closeRootScope(); // prints: CacheManager disposed!
|
||||
// Resolve from subScope, with fallback to parents if missing
|
||||
final dataBloc = await subScope.resolveAsync<DataBloc>();
|
||||
```
|
||||
|
||||
#### 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.

||||
### Dependency Lookup API
|
||||

## 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.
|
||||
|
||||

- **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.

### Q: Do I need to use `await` with CherryPick.closeRootScope(), CherryPick.closeScope(), or scope.dispose() if I have no Disposable services?
|
||||
## Documentation
|
||||
|
||||
**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.

### Fast Dependency Lookup (Performance Improvement)
|
||||
|
||||
> **Performance Note:**
|
||||
> **Starting from version 3.0.0**, CherryPick uses a Map-based resolver index for dependency lookup. This means calls to `resolve<T>()`, `tryResolve<T>()` and similar methods are now O(1) operations, regardless of the number of modules or bindings within your scope. Previously it would iterate over all modules and bindings, which could reduce performance as your project grew. This optimization is internal and does not affect the public API or usage patterns, but significantly improves resolution speed for larger applications.
|
||||
|
||||

||||

||||
|
||||
## Automatic resource management: Disposable and dispose
|
||||
|
||||
CherryPick makes it easy to clean up resources for your singleton services and other objects registered in DI.
|
||||
If your class implements the `Disposable` interface, always **await** `scope.dispose()` (or `CherryPick.closeRootScope()`) when you want to free all resources in your scope — CherryPick will automatically await `dispose()` for every object that implements `Disposable` and was resolved via DI.
|
||||
This ensures safe and graceful resource management (including any async resource cleanup: streams, DB connections, sockets, etc.).
|
||||
|
||||
### Example
|
||||
|
||||
```dart
|
||||
class LoggingService implements Disposable {
|
||||
@override
|
||||
FutureOr<void> dispose() async {
|
||||
// Close files, streams, and perform async cleanup here.
|
||||
print('LoggingService disposed!');
|
||||
}
|
||||
}
|
||||
|
||||
Future<void> main() async {
|
||||
final scope = openRootScope();
|
||||
scope.installModules([
|
||||
_LoggingModule(),
|
||||
]);
|
||||
final logger = scope.resolve<LoggingService>();
|
||||
// Use logger...
|
||||
await scope.dispose(); // prints: LoggingService disposed!
|
||||
}
|
||||
|
||||
class _LoggingModule extends Module {
|
||||
@override
|
||||
void builder(Scope scope) {
|

[`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.

|

|

## Logging
|
||||
|
||||
To enable logging of all dependency injection (DI) events and errors in CherryPick, set the global logger before creating your scopes:
|
||||
|
||||
```dart
|
||||
import 'package:cherrypick/cherrypick.dart';
|
||||
|
||||
void main() {
|
||||
// Set a global logger before any scopes are created
|
||||
CherryPick.setGlobalLogger(PrintLogger()); // or your own custom logger
|
||||
final scope = CherryPick.openRootScope();
|
||||
// All DI events and cycle errors will now be sent to your logger
|
||||
}
|
||||
```
|
||||
|
||||
- By default, CherryPick uses SilentLogger (no output in production).
|
||||
- Any dependency resolution, scope events, or cycle detection errors are logged via info/error on your logger.

## FAQ
|

|

### Q: Do I need to use `await` with CherryPick.closeRootScope(), CherryPick.closeScope(), or scope.dispose() if I have no Disposable services?
|
||||
|
||||
**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.

### Быстрый поиск зависимостей (Performance Improvement)
|
||||
|
||||
> **Примечание по производительности:**
|
||||
> Начиная с версии **3.0.0**, CherryPick для поиска зависимости внутри scope использует Map-индекс. Благодаря этому методы `resolve<T>()`, `tryResolve<T>()` и аналогичные теперь работают за O(1), независимо от количества модулей и биндингов в вашем проекте. Ранее для поиска приходилось перебирать весь список вручную, что могло замедлять работу крупных приложений. Это внутреннее улучшение не меняет внешнего API или паттернов использования, но заметно ускоряет разрешение зависимостей на больших проектах.

## Автоматическое управление ресурсами: Disposable и dispose
|
||||
|
||||
CherryPick позволяет автоматически очищать ресурсы для ваших синглтонов и любых сервисов, зарегистрированных через DI.
|
||||
Если ваш класс реализует интерфейс `Disposable`, всегда вызывайте и **await**-те `scope.dispose()` (или `CherryPick.closeRootScope()`), когда хотите освободить все ресурсы — CherryPick дождётся завершения `dispose()` для всех объектов, которые реализуют Disposable и были резолвлены из DI.
|
||||
Это позволяет избежать утечек памяти, корректно завершать процессы и грамотно освобождать любые ресурсы (файлы, потоки, соединения и т.д., включая async).
|
||||
|
||||
### Пример
|
||||
|
||||
```dart
|
||||
class LoggingService implements Disposable {
|
||||
@override
|
||||
FutureOr<void> dispose() async {
|
||||
// Закрыть файлы, потоки, соединения и т.д. (можно с await)
|
||||
print('LoggingService disposed!');
|
||||
}
|
||||
}
|
||||
|
||||
Future<void> main() async {
|
||||
final scope = openRootScope();
|
||||
scope.installModules([
|
||||
_LoggingModule(),
|
||||
]);
|
||||
final logger = scope.resolve<LoggingService>();
|
||||
// Используем logger...
|
||||
await scope.dispose(); // выведет: LoggingService disposed!
|
||||
}
|
||||
|
||||
class _LoggingModule extends Module {
|
||||
@override
|
||||
void builder(Scope scope) {
|
||||
bind<LoggingService>().toProvide(() => LoggingService()).singleton();
|
||||
}
|
||||
}
|
||||
```

## Логирование
|
||||
|
||||
Чтобы включить вывод логов о событиях и ошибках DI в CherryPick, настройте глобальный логгер до создания любых scope:
|
||||
|
||||
```dart
|
||||
import 'package:cherrypick/cherrypick.dart';
|
||||
|
||||
void main() {
|
||||
// Установите глобальный логгер до создания scope
|
||||
CherryPick.setGlobalLogger(PrintLogger()); // или свой логгер
|
||||
final scope = CherryPick.openRootScope();
|
||||
// Логи DI и циклов будут выводиться через ваш логгер
|
||||
}
|
||||
```
|
||||
|
||||
- По умолчанию используется SilentLogger (нет логов в продакшене).
|
||||
- Любые ошибки резолва и события циклов логируются через info/error на логгере.

### В: Нужно ли использовать `await` для CherryPick.closeRootScope(), CherryPick.closeScope() или scope.dispose(), если ни один сервис не реализует Disposable?
|
||||
|
||||
**О:**
|
||||
Да! Даже если в данный момент ни один сервис не реализует Disposable, всегда используйте `await` при закрытии скоупа. Если в будущем потребуется добавить освобождение ресурсов через dispose, CherryPick вызовет его автоматически без изменения завершения работы ваших скоупов. Такой подход делает управление ресурсами устойчивым и безопасным для любых изменений архитектуры.

### Automatic resource management (`Disposable`, `dispose`)
|
||||
|
||||
If your service implements the `Disposable` interface, CherryPick will automatically await `dispose()` when you close a scope.
|
||||
|
||||
**Best practice:**
|
||||
Always finish your work with `await Cherrypick.closeRootScope()` (for the root scope) or `await scope.closeSubScope('feature')` (for subscopes).
|
||||
These methods will automatically await `dispose()` on all resolved objects implementing `Disposable`, ensuring safe and complete cleanup (sync and async).
|
||||
|
||||
Manual `await scope.dispose()` is available if you manage scopes yourself.
|
||||
|
||||
#### Example
|
||||
|
||||
```dart
|
||||
class MyService implements Disposable {
|
||||
@override
|
||||
FutureOr<void> dispose() async {
|
||||
// release resources, close connections, perform async shutdown, etc.
|
||||
print('MyService disposed!');
|
||||
}
|
||||
}
|
||||
|
||||
final scope = openRootScope();
|
||||
scope.installModules([
|
||||
ModuleImpl(),
|
||||
]);
|
||||
|
||||
final service = scope.resolve<MyService>();
|
||||
|
||||
// ... use service
|
||||
|
||||
// Recommended:
|
||||
await Cherrypick.closeRootScope(); // will print: MyService disposed!
|
||||
|
||||
// Or, to close a subscope:
|
||||
await scope.closeSubScope('feature');
|
||||
|
||||
class ModuleImpl extends Module {
|
||||
@override
|
||||
void builder(Scope scope) {
|
||||
bind<MyService>().toProvide(() => MyService()).singleton();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Logging
|
||||
|
||||
To enable logging of all dependency injection (DI) events and errors in CherryPick, set the global logger before creating your scopes:
|
||||
|
||||
```dart
|
||||
import 'package:cherrypick/cherrypick.dart';
|
||||
|
||||
void main() {
|
||||
// Set a global logger before any scopes are created
|
||||
CherryPick.setGlobalLogger(PrintLogger()); // or your own custom logger
|
||||
final scope = CherryPick.openRootScope();
|
||||
// All DI events and cycle errors will now be sent to your logger
|
||||
}
|
||||
```
|
||||
|
||||
- By default, CherryPick uses SilentLogger (no output in production).
|
||||
- Any dependency resolution, scope events, or cycle detection errors are logged via info/error on your logger.

### Автоматическое управление ресурсами (`Disposable`, `dispose`)
|
||||
|
||||
Если ваш сервис реализует интерфейс `Disposable`, CherryPick автоматически дождётся выполнения `dispose()` при закрытии scope.
|
||||
|
||||
**Рекомендация:**
|
||||
Завершайте работу через `await Cherrypick.closeRootScope()` (для root scope) или `await scope.closeSubScope('feature')` (для подскоупов).
|
||||
Эти методы автоматически await-ят `dispose()` для всех разрешённых через DI объектов, реализующих `Disposable`, обеспечивая корректную очистку (sync и async) и высвобождение ресурсов.
|
||||
|
||||
Вызывайте `await scope.dispose()` если вы явно управляете custom-скоупом.
|
||||
|
||||
#### Пример
|
||||
|
||||
```dart
|
||||
class MyService implements Disposable {
|
||||
@override
|
||||
FutureOr<void> dispose() async {
|
||||
// закрытие ресурса, соединений, таймеров и т.п., async/await
|
||||
print('MyService disposed!');
|
||||
}
|
||||
}
|
||||
|
||||
final scope = openRootScope();
|
||||
scope.installModules([
|
||||
ModuleImpl(),
|
||||
]);
|
||||
|
||||
final service = scope.resolve<MyService>();
|
||||
|
||||
// ... используем сервис ...
|
||||
|
||||
// Рекомендуемый финал:
|
||||
await Cherrypick.closeRootScope(); // выведет в консоль 'MyService disposed!'
|
||||
|
||||
// Или для подскоупа:
|
||||
await scope.closeSubScope('feature');
|
||||
|
||||
class ModuleImpl extends Module {
|
||||
@override
|
||||
void builder(Scope scope) {
|
||||
bind<MyService>().toProvide(() => MyService()).singleton();
|
||||
}
|
||||

|
||||
final scope = CherryPick.openRootScope();
|
||||
// Логи DI и циклов будут выводиться через ваш логгер
|
||||
}
|
||||
