484061148d docs(binding,docs): clarify .singleton() with .toInstance() behavior in docs and API
- Add an explicit note and warning about the effect (or lack thereof) of calling `.singleton()` after `.toInstance()`:
  - in singleton() API doc-comment in binding.dart,
  - in README.md (after all binding usage patterns),
  - in full_tutorial_en.md and full_tutorial_ru.md.
- Explain that `.singleton()` has no effect on objects registered with `.toInstance()` — they are always single instance.
- Recommend `.singleton()` only for providers (toProvide/toProvideAsync), not direct instances.
- Improves clarity and prevents misuse/confusion for end users and future maintainers.

b5b672765e docs(binding,docs): explain .singleton() + parametric provider behavior
- Add an explicit warning and usage examples for .singleton() combined with toProvideWithParams/toProvideAsyncWithParams:
  - in API doc-comment for singleton() in binding.dart,
  - in README.md and both full tutorials (EN/RU).
- Show correct and incorrect usage/pitfalls for parameterized providers and singleton.
- Help users avoid unintended singleton caching when using providers with parameters.
- Motivation: Prevent common confusion, make advanced DI scenarios safer and more obvious.

722a4d7980 docs(di): clarify 'toInstance' binding limitations in builder
- Add explicit note for users about the impossibility to use scope.resolve<T>() for just-to-be-registered types inside Module.builder when registering chained dependencies via toInstance.
- Show correct and incorrect usage patterns, functional and anti-pattern Dart examples in RU and EN full tutorials.
- Add the warning to the main README after core concept bindings block, improving discoverability for users starting with the library.
- Motivation: Prevent common misuse and hard-to-debug runtime errors for users who construct chains using toInstance/resolve inside the builder.

## 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.
- **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 320340 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
- 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.
- **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** 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.
- **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 320340 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** 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.
- 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.

> ⚠️ **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) {

> ```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.
> **Note about `.singleton()` and `.toInstance()`:**
>
> Calling `.singleton()` after `.toInstance()` does **not** change the bindings 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.
### Module
A **Module** is a logical collection point for bindings, designed for grouping and initializing related dependencies. Implement the `builder` method to define how dependencies should be bound within the scope.

> If you declare a binding using `.toProvideWithParams((params) => ...)` (or its async variant) and then call `.singleton()`, the DI container will create and cache **only one instance** on the first `resolve` call—with the initial parameters.

> - The provider function receives parameters only on its first call,
> - After that, no matter what parameters are passed, the same instance is always returned.

> Use `.singleton()` with parameterized providers only if you are sure all parameters should always be identical, or you intentionally want a “master” instance. Otherwise, omit `.singleton()` to ensure a new object is constructed for every unique `params` value.

# 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}');
}
```

# 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](https://pub.dev/packages/talker_cherrypick_logger):
<!-- 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.

# 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.

# Binding
A **Binding** acts as a configuration for how to create or provide a particular dependency. Bindings support:
* Direct instance assignment (`toInstance()`, `toInstanceAsync()`)
* Lazy providers (sync/async functions)
* Provider functions supporting dynamic parameters
* Named instances for resolving by string key
* Optional singleton lifecycle
#### Example
```dart
void builder(Scope scope) {
// Provide a direct instance
bind<String>().toInstance("Hello world");
// Provide an async direct instance
bind<String>().toInstanceAsync(Future.value("Hello world"));
// Provide a lazy sync instance using a factory
bind<String>().toProvide(() => "Hello world");
// Provide a lazy async instance using a factory
bind<String>().toProvideAsync(() async => "Hello async world");
// Provide an instance with dynamic parameters (sync)
bind<String>().toProvideWithParams((params) => "Hello $params");
// Provide an instance with dynamic parameters (async)
bind<String>().toProvideAsyncWithParams((params) async => "Hello $params");
// Named instance for retrieval by name
bind<String>().toProvide(() => "Hello world").withName("my_string");
// Mark as singleton (only one instance within the scope)
bind<String>().toProvide(() => "Hello world").singleton();
}
```
> ⚠️ **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.
> **Note about `.singleton()` and `.toInstance()`:**
>
> Calling `.singleton()` after `.toInstance()` does **not** change the bindings 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.

# 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!');
}
}
final scope = CherryPick.openRootScope();
scope.installModules([
Module((bind) => bind<CacheManager>().toProvide(() => CacheManager()).singleton()),
]);
// ...later
await CherryPick.closeRootScope(); // prints: CacheManager disposed!
```
## 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.

# Module
A **Module** is a logical collection point for bindings, designed for grouping and initializing related dependencies. Implement the `builder` method to define how dependencies should be bound within the scope.
## Example
```dart
class AppModule extends Module {
@override
void builder(Scope currentScope) {
bind<ApiClient>().toInstance(ApiClientMock());
bind<String>().toProvide(() => "Hello world!");
}

# Scope
A **Scope** manages a tree of modules and dependency instances. Scopes can be nested into hierarchies (parent-child), supporting modular app composition and context-specific overrides.
You typically work with the root scope, but can also create named subscopes as needed.
## Example
```dart
// Open the main/root scope
final rootScope = CherryPick.openRootScope();
// Install a custom module
rootScope.installModules([AppModule()]);
// Resolve a dependency synchronously
final str = rootScope.resolve<String>();
// Resolve a dependency asynchronously
final result = await rootScope.resolveAsync<String>();
// Recommended: Close the root scope and release all resources
await CherryPick.closeRootScope();
// Alternatively, you may manually call dispose on any scope you manage individually
// await rootScope.dispose();
```

- `resolve<T>()` — Locates a dependency instance or throws if missing.
- `resolveAsync<T>()` — Async variant for dependencies requiring async binding.
- `tryResolve<T>()` — Returns `null` if not found (sync).
- `tryResolveAsync<T>()` — Returns `null` async if not found.
Supports:
- Synchronous and asynchronous dependencies
- Named dependencies
- Provider functions with and without runtime parameters

# Example Application
Below is a complete example illustrating modules, subscopes, async providers, and dependency resolution.
```dart
import 'dart:async';
import 'package:meta/meta.dart';
import 'package:cherrypick/cherrypick.dart';
class AppModule extends Module {
@override
void builder(Scope currentScope) {
bind<ApiClient>().withName("apiClientMock").toInstance(ApiClientMock());
bind<ApiClient>().withName("apiClientImpl").toInstance(ApiClientImpl());
}
}
class FeatureModule extends Module {
final bool isMock;
FeatureModule({required this.isMock});
@override
void builder(Scope currentScope) {
// Async provider for DataRepository with named dependency selection
bind<DataRepository>()
.withName("networkRepo")
.toProvideAsync(() async {
final client = await Future.delayed(
Duration(milliseconds: 100),
() => currentScope.resolve<ApiClient>(
named: isMock ? "apiClientMock" : "apiClientImpl",
),
);
return NetworkDataRepository(client);
})
.singleton();
// Chained async provider for DataBloc
bind<DataBloc>().toProvideAsync(
() async {
final repo = await currentScope.resolveAsync<DataRepository>(
named: "networkRepo");
return DataBloc(repo);
},
);
}
}
void main() async {
final scope = CherryPick.openRootScope().installModules([AppModule()]);
final featureScope = scope.openSubScope("featureScope")
..installModules([FeatureModule(isMock: true)]);
final dataBloc = await featureScope.resolveAsync<DataBloc>();
dataBloc.data.listen(
(d) => print('Received data: $d'),
onError: (e) => print('Error: $e'),
onDone: () => print('DONE'),
);
await dataBloc.fetchData();
}
class DataBloc {
final DataRepository _dataRepository;
Stream<String> get data => _dataController.stream;
final StreamController<String> _dataController = StreamController.broadcast();
DataBloc(this._dataRepository);
Future<void> fetchData() async {
try {
_dataController.sink.add(await _dataRepository.getData());
} catch (e) {
_dataController.sink.addError(e);
}
}
void dispose() {
_dataController.close();
}
}
abstract class DataRepository {
Future<String> getData();
}
class NetworkDataRepository implements DataRepository {
final ApiClient _apiClient;
final _token = 'token';
NetworkDataRepository(this._apiClient);
@override
Future<String> getData() async =>
await _apiClient.sendRequest(
url: 'www.google.com',
token: _token,
requestBody: {'type': 'data'},
);
}
abstract class ApiClient {
Future sendRequest({@required String? url, String? token, Map? requestBody});
}
class ApiClientMock implements ApiClient {
@override
Future sendRequest(
{@required String? url, String? token, Map? requestBody}) async {
return 'Local Data';
}
}
class ApiClientImpl implements ApiClient {
@override
Future sendRequest(
{@required String? url, String? token, Map? requestBody}) async {
return 'Network data';
}
}
```

# 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.

# 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();
```
