+## Quick Guide: 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)

-You can further control the filenames and subdirectory structure of generated files using the `build_extensions` option in `build.yaml`. This is especially useful in large apps for keeping DI artifacts organized under `lib/generated/` or any custom location.

-- **output_dir**: Path where all generated files are placed (e.g., `lib/generated`)
-- **build_extensions**: Allows templating of generated filenames and locations. You can use wildcards like `{{}}` to keep directory structure or group related files.
-
-**If you use these options, be sure to update your imports accordingly, for example:**
-
-```dart
-import 'package:your_package/generated/app.inject.cherrypick.g.dart';
-import 'package:your_package/generated/di/app_module.module.cherrypick.g.dart';
-```
-
-### FAQ / Troubleshooting
-
-- If files are missing or located in unexpected directories, double-check your `output_dir` and `build_extensions` configuration.
-- If you change generation paths, always update your imports in the codebase.
-- These options are backward compatible: omitting them preserves pre-existing (side-by-source) output behavior.

 ## Advanced Usage
 
-### Custom output directory for generated code (output_dir)
-
-You can control the directory where the generated files (`*.inject.cherrypick.g.dart`, `*.module.cherrypick.g.dart`) are placed using the `output_dir` option in your `build.yaml`:
-
-```yaml
-targets:
-  $default:
-    builders:
-      cherrypick_generator|injectBuilder:
-        options:
-          output_dir: lib/generated
-      cherrypick_generator|moduleBuilder:
-        options:
-          output_dir: lib/generated
-```
-
-**If `output_dir` is omitted, generated files are placed next to the original sources (default behavior).**
-
-After running code generation, you will find files like `lib/generated/app.inject.cherrypick.g.dart` and `lib/generated/your_module.module.cherrypick.g.dart`. You can import them as needed from that directory.

 - **Combining Modules and Field Injection:**  
   It's possible to mix both style of DI — modules for binding, and field injection for consuming services.
 - **Parameter and Named Injection:**

+# Circular Dependency Detection
+
+CherryPick provides robust circular dependency detection to prevent infinite loops and stack overflow errors in your dependency injection setup.
+
+## What are Circular Dependencies?
+
+Circular dependencies occur when two or more services depend on each other directly or indirectly, creating a cycle in the dependency graph.
+
+### Example of circular dependencies within a scope
+
+```dart
+class UserService {
+  final OrderService orderService;
+  UserService(this.orderService);
+}
+
+class OrderService {
+  final UserService userService;
+  OrderService(this.userService);
+}
+```
+
+### Example of circular dependencies between scopes
+
+```dart
+// In parent scope
+class ParentService {
+  final ChildService childService;
+  ParentService(this.childService); // Gets from child scope
+}
+
+// In child scope
+class ChildService {
+  final ParentService parentService;
+  ChildService(this.parentService); // Gets from parent scope
+}
+```
+
+## Detection Types
+
+### 🔍 Local Detection
+
+Detects circular dependencies within a single scope. Fast and efficient.
+
+### 🌐 Global Detection
+
+Detects circular dependencies across the entire scope hierarchy. Slower but provides complete protection.
+
+## Usage
+
+### Local Detection
+
+```dart
+final scope = Scope(null);
+scope.enableCycleDetection(); // Enable local detection
+
+scope.installModules([
+  Module((bind) {
+    bind<UserService>().to((scope) => UserService(scope.resolve<OrderService>()));
+    bind<OrderService>().to((scope) => OrderService(scope.resolve<UserService>()));
+  }),
+]);
+
+try {
+  final userService = scope.resolve<UserService>(); // Will throw CircularDependencyException
+} catch (e) {
+  print(e); // CircularDependencyException: Circular dependency detected
+}
+```
+
+### Global Detection
+
+```dart
+// Enable global detection for all scopes
+CherryPick.enableGlobalCrossScopeCycleDetection();
+
+final rootScope = CherryPick.openGlobalSafeRootScope();
+final childScope = rootScope.openSubScope();
+
+// Configure dependencies that create cross-scope cycles
+rootScope.installModules([
+  Module((bind) {
+    bind<ParentService>().to((scope) => ParentService(childScope.resolve<ChildService>()));
+  }),
+]);
+
+childScope.installModules([
+  Module((bind) {
+    bind<ChildService>().to((scope) => ChildService(rootScope.resolve<ParentService>()));
+  }),
+]);
+
+try {
+  final parentService = rootScope.resolve<ParentService>(); // Will throw CircularDependencyException
+} catch (e) {
+  print(e); // CircularDependencyException with detailed chain information
+}
+```
+
+## CherryPick Helper API
+
+### Global Settings
+
+```dart
+// Enable/disable local detection globally
+CherryPick.enableGlobalCycleDetection();
+CherryPick.disableGlobalCycleDetection();
+
+// Enable/disable global cross-scope detection
+CherryPick.enableGlobalCrossScopeCycleDetection();
+CherryPick.disableGlobalCrossScopeCycleDetection();
+
+// Check current settings
+bool localEnabled = CherryPick.isGlobalCycleDetectionEnabled;
+bool globalEnabled = CherryPick.isGlobalCrossScopeCycleDetectionEnabled;
+```
+
+### Per-Scope Settings
+
+```dart
+// Enable/disable for specific scope
+CherryPick.enableCycleDetectionForScope(scope);
+CherryPick.disableCycleDetectionForScope(scope);
+
+// Enable/disable global detection for specific scope
+CherryPick.enableGlobalCycleDetectionForScope(scope);
+CherryPick.disableGlobalCycleDetectionForScope(scope);
+```
+
+### Safe Scope Creation
+
+```dart
+// Create scopes with detection automatically enabled
+final safeRootScope = CherryPick.openSafeRootScope(); // Local detection enabled
+final globalSafeRootScope = CherryPick.openGlobalSafeRootScope(); // Both local and global enabled
+final safeSubScope = CherryPick.openSafeSubScope(parentScope); // Inherits parent settings
+```
+
+## Performance Considerations
+
+| Detection Type | Overhead | Recommended Usage |
+|----------------|----------|-------------------|
+| **Local** | Minimal (~5%) | Development, Testing |
+| **Global** | Moderate (~15%) | Complex hierarchies, Critical features |
+| **Disabled** | None | Production (after testing) |
+
+### Recommendations
+
+- **Development**: Enable both local and global detection for maximum safety
+- **Testing**: Keep detection enabled to catch issues early
+- **Production**: Consider disabling for performance, but only after thorough testing
+
+```dart
+import 'package:flutter/foundation.dart';
+
+void configureCycleDetection() {
+  if (kDebugMode) {
+    // Enable full protection in debug mode
+    CherryPick.enableGlobalCycleDetection();
+    CherryPick.enableGlobalCrossScopeCycleDetection();
+  } else {
+    // Disable in release mode for performance
+    CherryPick.disableGlobalCycleDetection();
+    CherryPick.disableGlobalCrossScopeCycleDetection();
+  }
+}
+```
+
+## Architectural Patterns
+
+### Repository Pattern
+
+```dart
+// ✅ Correct: Repository doesn't depend on service
+class UserRepository {
+  final ApiClient apiClient;
+  UserRepository(this.apiClient);
+}
+
+class UserService {
+  final UserRepository repository;
+  UserService(this.repository);
+}
+
+// ❌ Incorrect: Circular dependency
+class UserRepository {
+  final UserService userService; // Don't do this!
+  UserRepository(this.userService);
+}
+```
+
+### Mediator Pattern
+
+```dart
+// ✅ Correct: Use mediator to break cycles
+abstract class EventBus {
+  void publish<T>(T event);
+  Stream<T> listen<T>();
+}
+
+class UserService {
+  final EventBus eventBus;
+  UserService(this.eventBus);
+  
+  void createUser(User user) {
+    // ... create user logic
+    eventBus.publish(UserCreatedEvent(user));
+  }
+}
+
+class OrderService {
+  final EventBus eventBus;
+  OrderService(this.eventBus) {
+    eventBus.listen<UserCreatedEvent>().listen(_onUserCreated);
+  }
+  
+  void _onUserCreated(UserCreatedEvent event) {
+    // React to user creation without direct dependency
+  }
+}
+```
+
+## Scope Hierarchy Best Practices
+
+### Proper Dependency Flow
+
+```dart
+// ✅ Correct: Dependencies flow downward in hierarchy
+// Root Scope: Core services
+final rootScope = CherryPick.openGlobalSafeRootScope();
+rootScope.installModules([
+  Module((bind) {
+    bind<DatabaseService>().singleton((scope) => DatabaseService());
+    bind<ApiClient>().singleton((scope) => ApiClient());
+  }),
+]);
+
+// Feature Scope: Feature-specific services
+final featureScope = rootScope.openSubScope();
+featureScope.installModules([
+  Module((bind) {
+    bind<UserRepository>().to((scope) => UserRepository(scope.resolve<ApiClient>()));
+    bind<UserService>().to((scope) => UserService(scope.resolve<UserRepository>()));
+  }),
+]);
+
+// UI Scope: UI-specific services
+final uiScope = featureScope.openSubScope();
+uiScope.installModules([
+  Module((bind) {
+    bind<UserController>().to((scope) => UserController(scope.resolve<UserService>()));
+  }),
+]);
+```
+
+### Avoid Cross-Scope Dependencies
+
+```dart
+// ❌ Incorrect: Child scope depending on parent's specific services
+childScope.installModules([
+  Module((bind) {
+    bind<ChildService>().to((scope) => 
+      ChildService(rootScope.resolve<ParentService>()) // Risky!
+    );
+  }),
+]);
+
+// ✅ Correct: Use interfaces and proper dependency injection
+abstract class IParentService {
+  void doSomething();
+}
+
+class ParentService implements IParentService {
+  void doSomething() { /* implementation */ }
+}
+
+// In root scope
+rootScope.installModules([
+  Module((bind) {
+    bind<IParentService>().to((scope) => ParentService());
+  }),
+]);
+
+// In child scope - resolve through normal hierarchy
+childScope.installModules([
+  Module((bind) {
+    bind<ChildService>().to((scope) => 
+      ChildService(scope.resolve<IParentService>()) // Safe!
+    );
+  }),
+]);
+```
+
+## Debug Mode
+
+### Resolution Chain Tracking
+
+```dart
+// Enable debug mode to track resolution chains
+final scope = CherryPick.openGlobalSafeRootScope();
+
+// Access current resolution chain for debugging
+print('Current resolution chain: ${scope.currentResolutionChain}');
+
+// Access global resolution chain
+print('Global resolution chain: ${GlobalCycleDetector.instance.currentGlobalResolutionChain}');
+```
+
+### Exception Details
+
+```dart
+try {
+  final service = scope.resolve<CircularService>();
+} on CircularDependencyException catch (e) {
+  print('Error: ${e.message}');
+  print('Dependency chain: ${e.dependencyChain.join(' -> ')}');
+  
+  // For global detection, additional context is available
+  if (e.message.contains('cross-scope')) {
+    print('This is a cross-scope circular dependency');
+  }
+}
+```
+
+## Testing Integration
+
+### Unit Tests
+
+```dart
+import 'package:test/test.dart';
+import 'package:cherrypick/cherrypick.dart';
+
+void main() {
+  group('Circular Dependency Detection', () {
+    setUp(() {
+      // Enable detection for tests
+      CherryPick.enableGlobalCycleDetection();
+      CherryPick.enableGlobalCrossScopeCycleDetection();
+    });
+    
+    tearDown(() {
+      // Clean up after tests
+      CherryPick.disableGlobalCycleDetection();
+      CherryPick.disableGlobalCrossScopeCycleDetection();
+    });
+    
+    test('should detect circular dependency', () {
+      final scope = CherryPick.openGlobalSafeRootScope();
+      
+      scope.installModules([
+        Module((bind) {
+          bind<ServiceA>().to((scope) => ServiceA(scope.resolve<ServiceB>()));
+          bind<ServiceB>().to((scope) => ServiceB(scope.resolve<ServiceA>()));
+        }),
+      ]);
+      
+      expect(
+        () => scope.resolve<ServiceA>(),
+        throwsA(isA<CircularDependencyException>()),
+      );
+    });

+  await tester.pumpWidget(
+    CherryPickProvider(
+      create: () {
+        final scope = CherryPick.openGlobalSafeRootScope();
+        // Configure modules that might have cycles
+        return scope;
+      },
+      child: MyApp(),
+    ),
+  );
+  
+  // Test that circular dependencies are properly handled
+  expect(find.text('Error: Circular dependency detected'), findsNothing);
+});
+```
+
+## Migration Guide
+
+### From Version 2.1.x to 2.2.x
+
+1. **Update dependencies**:
+   ```yaml
+   dependencies:
+     cherrypick: ^2.2.0
+   ```
+
+2. **Enable detection in existing code**:
+   ```dart
+   // Before
+   final scope = Scope(null);
+   
+   // After - with local detection
+   final scope = CherryPick.openSafeRootScope();
+   
+   // Or with global detection
+   final scope = CherryPick.openGlobalSafeRootScope();
+   ```
+
+3. **Update error handling**:
+   ```dart
+   try {
+     final service = scope.resolve<MyService>();
+   } on CircularDependencyException catch (e) {
+     // Handle circular dependency errors
+     logger.error('Circular dependency detected: ${e.dependencyChain}');
+   }
+   ```
+
+4. **Configure for production**:
+   ```dart
+   void main() {
+     // Configure detection based on build mode
+     if (kDebugMode) {
+       CherryPick.enableGlobalCycleDetection();
+       CherryPick.enableGlobalCrossScopeCycleDetection();
+     }
+     
+     runApp(MyApp());
+   }
+   ```
+
+## API Reference
+
+### Scope Methods
+
+```dart
+class Scope {
+  // Local cycle detection
+  void enableCycleDetection();

+  static Scope openGlobalSafeRootScope();
+  static Scope openSafeSubScope(Scope parent);
+}
+```
+
+### Exception Classes
+
+```dart
+class CircularDependencyException implements Exception {
+  final String message;
+  final List<String> dependencyChain;
+  
+  const CircularDependencyException(this.message, this.dependencyChain);
+  
+  @override
+  String toString() {
+    final chain = dependencyChain.join(' -> ');
+    return 'CircularDependencyException: $message\nDependency chain: $chain';
+  }
+}
+```
+
+## Best Practices
+
+### 1. Enable Detection During Development
+
+```dart
+void main() {
+  if (kDebugMode) {
+    CherryPick.enableGlobalCycleDetection();
+    CherryPick.enableGlobalCrossScopeCycleDetection();
+  }
+  
+  runApp(MyApp());
+}
+```
+
+### 2. Use Safe Scope Creation
+
+```dart
+// Instead of
+final scope = Scope(null);
+
+// Use
+final scope = CherryPick.openGlobalSafeRootScope();
+```
+
+### 3. Design Proper Architecture
+
+- Follow single responsibility principle
+- Use interfaces to decouple dependencies
+- Implement mediator pattern for complex interactions
+- Keep dependency flow unidirectional in scope hierarchy
+
+### 4. Handle Errors Gracefully
+
+```dart
+T resolveSafely<T>() {
+  try {
+    return scope.resolve<T>();
+  } on CircularDependencyException catch (e) {
+    logger.error('Circular dependency detected', e);
+    rethrow;
+  }
+}
+```
+
+### 5. Test Thoroughly
+
+- Write unit tests for dependency configurations
+- Use integration tests to verify complex scenarios
+- Enable detection in test environments
+- Test both positive and negative scenarios
+
+## Troubleshooting
+
+### Common Issues
+
+1. **False Positives**: If you're getting false circular dependency errors, check if you have proper async handling in your providers.
+
+2. **Performance Issues**: If global detection is too slow, consider using only local detection or disabling it in production.
+
+3. **Complex Hierarchies**: For very complex scope hierarchies, consider simplifying your architecture or using more interfaces.
+
+### Debug Tips
+
+1. **Check Resolution Chain**: Use `scope.currentResolutionChain` to see the current dependency resolution path.
+
+2. **Enable Logging**: Add logging to your providers to trace dependency resolution.
+
+3. **Simplify Dependencies**: Break complex dependencies into smaller, more manageable pieces.
+
+4. **Use Interfaces**: Abstract dependencies behind interfaces to reduce coupling.
+
+## Conclusion
+
+Circular dependency detection in CherryPick provides robust protection against infinite loops and stack overflow errors. By following the best practices and using the appropriate detection level for your use case, you can build reliable and maintainable dependency injection configurations.

+# Обнаружение циклических зависимостей
+
+CherryPick предоставляет надежное обнаружение циклических зависимостей для предотвращения бесконечных циклов и ошибок переполнения стека в вашей настройке внедрения зависимостей.
+
+## Что такое циклические зависимости?
+
+Циклические зависимости возникают, когда два или более сервиса зависят друг от друга прямо или косвенно, создавая цикл в графе зависимостей.
+
+### Пример циклических зависимостей в рамках скоупа
+
+```dart
+class UserService {
+  final OrderService orderService;
+  UserService(this.orderService);
+}
+
+class OrderService {
+  final UserService userService;
+  OrderService(this.userService);
+}
+```
+
+### Пример циклических зависимостей между скоупами
+
+```dart
+// В родительском скоупе
+class ParentService {
+  final ChildService childService;
+  ParentService(this.childService); // Получает из дочернего скоупа
+}
+
+// В дочернем скоупе
+class ChildService {
+  final ParentService parentService;
+  ChildService(this.parentService); // Получает из родительского скоупа
+}
+```
+
+## Типы обнаружения
+
+### 🔍 Локальное обнаружение
+
+Обнаруживает циклические зависимости в рамках одного скоупа. Быстрое и эффективное.
+
+### 🌐 Глобальное обнаружение
+
+Обнаруживает циклические зависимости во всей иерархии скоупов. Более медленное, но обеспечивает полную защиту.
+
+## Использование
+
+### Локальное обнаружение
+
+```dart
+final scope = Scope(null);
+scope.enableCycleDetection(); // Включить локальное обнаружение
+
+scope.installModules([
+  Module((bind) {
+    bind<UserService>().to((scope) => UserService(scope.resolve<OrderService>()));
+    bind<OrderService>().to((scope) => OrderService(scope.resolve<UserService>()));
+  }),
+]);
+
+try {
+  final userService = scope.resolve<UserService>(); // Выбросит CircularDependencyException
+} catch (e) {
+  print(e); // CircularDependencyException: Circular dependency detected
+}
+```
+
+### Глобальное обнаружение
+
+```dart
+// Включить глобальное обнаружение для всех скоупов
+CherryPick.enableGlobalCrossScopeCycleDetection();
+
+final rootScope = CherryPick.openGlobalSafeRootScope();
+final childScope = rootScope.openSubScope();
+
+// Настроить зависимости, которые создают межскоуповые циклы
+rootScope.installModules([
+  Module((bind) {
+    bind<ParentService>().to((scope) => ParentService(childScope.resolve<ChildService>()));
+  }),
+]);
+
+childScope.installModules([
+  Module((bind) {
+    bind<ChildService>().to((scope) => ChildService(rootScope.resolve<ParentService>()));
+  }),
+]);
+
+try {
+  final parentService = rootScope.resolve<ParentService>(); // Выбросит CircularDependencyException
+} catch (e) {
+  print(e); // CircularDependencyException с детальной информацией о цепочке
+}
+```
+
+## API CherryPick Helper
+
+### Глобальные настройки
+
+```dart
+// Включить/отключить локальное обнаружение глобально
+CherryPick.enableGlobalCycleDetection();
+CherryPick.disableGlobalCycleDetection();
+
+// Включить/отключить глобальное межскоуповое обнаружение
+CherryPick.enableGlobalCrossScopeCycleDetection();
+CherryPick.disableGlobalCrossScopeCycleDetection();
+
+// Проверить текущие настройки
+bool localEnabled = CherryPick.isGlobalCycleDetectionEnabled;
+bool globalEnabled = CherryPick.isGlobalCrossScopeCycleDetectionEnabled;
+```
+
+### Настройки для конкретного скоупа
+
+```dart
+// Включить/отключить для конкретного скоупа
+CherryPick.enableCycleDetectionForScope(scope);
+CherryPick.disableCycleDetectionForScope(scope);
+
+// Включить/отключить глобальное обнаружение для конкретного скоупа
+CherryPick.enableGlobalCycleDetectionForScope(scope);
+CherryPick.disableGlobalCycleDetectionForScope(scope);
+```
+
+### Безопасное создание скоупов
+
+```dart
+// Создать скоупы с автоматически включенным обнаружением
+final safeRootScope = CherryPick.openSafeRootScope(); // Локальное обнаружение включено
+final globalSafeRootScope = CherryPick.openGlobalSafeRootScope(); // Включены локальное и глобальное
+final safeSubScope = CherryPick.openSafeSubScope(parentScope); // Наследует настройки родителя
+```
+
+## Соображения производительности
+
+| Тип обнаружения | Накладные расходы | Рекомендуемое использование |
+|-----------------|-------------------|----------------------------|
+| **Локальное** | Минимальные (~5%) | Разработка, тестирование |
+| **Глобальное** | Умеренные (~15%) | Сложные иерархии, критические функции |
+| **Отключено** | Нет | Продакшн (после тестирования) |
+
+### Рекомендации
+
+- **Разработка**: Включите локальное и глобальное обнаружение для максимальной безопасности
+- **Тестирование**: Оставьте обнаружение включенным для раннего выявления проблем
+- **Продакшн**: Рассмотрите отключение для производительности, но только после тщательного тестирования
+
+```dart
+import 'package:flutter/foundation.dart';
+
+void configureCycleDetection() {
+  if (kDebugMode) {
+    // Включить полную защиту в режиме отладки
+    CherryPick.enableGlobalCycleDetection();
+    CherryPick.enableGlobalCrossScopeCycleDetection();
+  } else {
+    // Отключить в релизном режиме для производительности
+    CherryPick.disableGlobalCycleDetection();
+    CherryPick.disableGlobalCrossScopeCycleDetection();
+  }
+}
+```
+
+## Архитектурные паттерны
+
+### Паттерн Repository
+
+```dart
+// ✅ Правильно: Repository не зависит от сервиса
+class UserRepository {
+  final ApiClient apiClient;
+  UserRepository(this.apiClient);
+}
+
+class UserService {
+  final UserRepository repository;
+  UserService(this.repository);
+}
+
+// ❌ Неправильно: Циклическая зависимость
+class UserRepository {
+  final UserService userService; // Не делайте так!
+  UserRepository(this.userService);
+}
+```
+
+### Паттерн Mediator
+
+```dart
+// ✅ Правильно: Используйте медиатор для разрыва циклов
+abstract class EventBus {
+  void publish<T>(T event);
+  Stream<T> listen<T>();
+}
+
+class UserService {
+  final EventBus eventBus;
+  UserService(this.eventBus);
+  
+  void createUser(User user) {
+    // ... логика создания пользователя
+    eventBus.publish(UserCreatedEvent(user));
+  }
+}
+
+class OrderService {
+  final EventBus eventBus;
+  OrderService(this.eventBus) {
+    eventBus.listen<UserCreatedEvent>().listen(_onUserCreated);
+  }
+  
+  void _onUserCreated(UserCreatedEvent event) {
+    // Реагировать на создание пользователя без прямой зависимости
+  }
+}
+```
+
+## Лучшие практики иерархии скоупов
+
+### Правильный поток зависимостей
+
+```dart
+// ✅ Правильно: Зависимости текут вниз по иерархии
+// Корневой скоуп: Основные сервисы
+final rootScope = CherryPick.openGlobalSafeRootScope();
+rootScope.installModules([
+  Module((bind) {
+    bind<DatabaseService>().singleton((scope) => DatabaseService());
+    bind<ApiClient>().singleton((scope) => ApiClient());
+  }),
+]);
+
+// Скоуп функции: Сервисы, специфичные для функции
+final featureScope = rootScope.openSubScope();
+featureScope.installModules([
+  Module((bind) {
+    bind<UserRepository>().to((scope) => UserRepository(scope.resolve<ApiClient>()));
+    bind<UserService>().to((scope) => UserService(scope.resolve<UserRepository>()));
+  }),
+]);
+
+// UI скоуп: Сервисы, специфичные для UI
+final uiScope = featureScope.openSubScope();
+uiScope.installModules([
+  Module((bind) {
+    bind<UserController>().to((scope) => UserController(scope.resolve<UserService>()));
+  }),
+]);
+```
+
+### Избегайте межскоуповых зависимостей
+
+```dart
+// ❌ Неправильно: Дочерний скоуп зависит от конкретных сервисов родителя
+childScope.installModules([
+  Module((bind) {
+    bind<ChildService>().to((scope) => 
+      ChildService(rootScope.resolve<ParentService>()) // Рискованно!
+    );
+  }),
+]);
+
+// ✅ Правильно: Используйте интерфейсы и правильное внедрение зависимостей
+abstract class IParentService {
+  void doSomething();
+}
+
+class ParentService implements IParentService {
+  void doSomething() { /* реализация */ }
+}
+
+// В корневом скоупе
+rootScope.installModules([
+  Module((bind) {
+    bind<IParentService>().to((scope) => ParentService());
+  }),
+]);
+
+// В дочернем скоупе - разрешение через обычную иерархию
+childScope.installModules([
+  Module((bind) {
+    bind<ChildService>().to((scope) => 
+      ChildService(scope.resolve<IParentService>()) // Безопасно!
+    );
+  }),
+]);
+```
+
+## Режим отладки
+
+### Отслеживание цепочки разрешения
+
+```dart
+// Включить режим отладки для отслеживания цепочек разрешения
+final scope = CherryPick.openGlobalSafeRootScope();
+
+// Доступ к текущей цепочке разрешения для отладки
+print('Текущая цепочка разрешения: ${scope.currentResolutionChain}');
+
+// Доступ к глобальной цепочке разрешения
+print('Глобальная цепочка разрешения: ${GlobalCycleDetector.instance.currentGlobalResolutionChain}');
+```
+
+### Детали исключений
+
+```dart
+try {
+  final service = scope.resolve<CircularService>();
+} on CircularDependencyException catch (e) {
+  print('Ошибка: ${e.message}');
+  print('Цепочка зависимостей: ${e.dependencyChain.join(' -> ')}');
+  
+  // Для глобального обнаружения доступен дополнительный контекст
+  if (e.message.contains('cross-scope')) {
+    print('Это межскоуповая циклическая зависимость');
+  }
+}
+```
+
+## Интеграция с тестированием
+
+### Модульные тесты
+
+```dart
+import 'package:test/test.dart';
+import 'package:cherrypick/cherrypick.dart';
+
+void main() {
+  group('Обнаружение циклических зависимостей', () {
+    setUp(() {
+      // Включить обнаружение для тестов
+      CherryPick.enableGlobalCycleDetection();
+      CherryPick.enableGlobalCrossScopeCycleDetection();
+    });
+    
+    tearDown(() {
+      // Очистка после тестов
+      CherryPick.disableGlobalCycleDetection();
+      CherryPick.disableGlobalCrossScopeCycleDetection();
+    });
+    
+    test('должен обнаружить циклическую зависимость', () {
+      final scope = CherryPick.openGlobalSafeRootScope();
+      
+      scope.installModules([
+        Module((bind) {
+          bind<ServiceA>().to((scope) => ServiceA(scope.resolve<ServiceB>()));
+          bind<ServiceB>().to((scope) => ServiceB(scope.resolve<ServiceA>()));
+        }),
+      ]);
+      
+      expect(
+        () => scope.resolve<ServiceA>(),
+        throwsA(isA<CircularDependencyException>()),
+      );
+    });
+  });
+}
+```
+
+### Интеграционные тесты
+
+```dart
+testWidgets('должен обрабатывать циклические зависимости в дереве виджетов', (tester) async {
+  // Включить обнаружение
+  CherryPick.enableGlobalCycleDetection();
+  
+  await tester.pumpWidget(
+    CherryPickProvider(
+      create: () {
+        final scope = CherryPick.openGlobalSafeRootScope();
+        // Настроить модули, которые могут иметь циклы
+        return scope;
+      },
+      child: MyApp(),
+    ),
+  );
+  
+  // Проверить, что циклические зависимости правильно обрабатываются
+  expect(find.text('Ошибка: Обнаружена циклическая зависимость'), findsNothing);
+});
+```
+
+## Руководство по миграции
+
+### С версии 2.1.x на 2.2.x
+
+1. **Обновите зависимости**:
+   ```yaml
+   dependencies:
+     cherrypick: ^2.2.0
+   ```
+
+2. **Включите обнаружение в существующем коде**:
+   ```dart
+   // Раньше
+   final scope = Scope(null);
+   
+   // Теперь - с локальным обнаружением
+   final scope = CherryPick.openSafeRootScope();
+   
+   // Или с глобальным обнаружением
+   final scope = CherryPick.openGlobalSafeRootScope();
+   ```
+
+3. **Обновите обработку ошибок**:
+   ```dart
+   try {
+     final service = scope.resolve<MyService>();
+   } on CircularDependencyException catch (e) {
+     // Обработать ошибки циклических зависимостей
+     logger.error('Обнаружена циклическая зависимость: ${e.dependencyChain}');
+   }
+   ```
+
+4. **Настройте для продакшна**:
+   ```dart
+   void main() {
+     // Настроить обнаружение в зависимости от режима сборки
+     if (kDebugMode) {
+       CherryPick.enableGlobalCycleDetection();
+       CherryPick.enableGlobalCrossScopeCycleDetection();
+     }
+     
+     runApp(MyApp());
+   }
+   ```

+  final List<String> dependencyChain;
+  
+  const CircularDependencyException(this.message, this.dependencyChain);
+  
+  @override
+  String toString() {
+    final chain = dependencyChain.join(' -> ');
+    return 'CircularDependencyException: $message\nЦепочка зависимостей: $chain';
+  }
+}
+```
+
+## Лучшие практики
+
+### 1. Включайте обнаружение во время разработки
+
+```dart
+void main() {
+  if (kDebugMode) {
+    CherryPick.enableGlobalCycleDetection();
+    CherryPick.enableGlobalCrossScopeCycleDetection();
+  }
+  
+  runApp(MyApp());
+}
+```
+
+### 2. Используйте безопасное создание скоупов
+
+```dart
+// Вместо
+final scope = Scope(null);
+
+// Используйте
+final scope = CherryPick.openGlobalSafeRootScope();
+```
+
+### 3. Проектируйте правильную архитектуру
+
+- Следуйте принципу единственной ответственности
+- Используйте интерфейсы для разделения зависимостей
+- Реализуйте паттерн медиатор для сложных взаимодействий
+- Поддерживайте однонаправленный поток зависимостей в иерархии скоупов
+
+### 4. Обрабатывайте ошибки корректно
+
+```dart
+T resolveSafely<T>() {
+  try {
+    return scope.resolve<T>();
+  } on CircularDependencyException catch (e) {
+    logger.error('Обнаружена циклическая зависимость', e);
+    rethrow;
+  }
+}
+```
+
+### 5. Тестируйте тщательно
+
+- Пишите модульные тесты для конфигураций зависимостей
+- Используйте интеграционные тесты для проверки сложных сценариев
+- Включайте обнаружение в тестовых средах
+- Тестируйте как положительные, так и отрицательные сценарии
+
+## Устранение неполадок
+
+### Распространенные проблемы
+
+1. **Ложные срабатывания**: Если вы получаете ложные ошибки циклических зависимостей, проверьте правильность обработки async в ваших провайдерах.
+
+2. **Проблемы производительности**: Если глобальное обнаружение слишком медленное, рассмотрите использование только локального обнаружения или отключение в продакшне.
+
+3. **Сложные иерархии**: Для очень сложных иерархий скоупов рассмотрите упрощение архитектуры или использование большего количества интерфейсов.
+
+### Советы по отладке
+
+1. **Проверьте цепочку разрешения**: Используйте `scope.currentResolutionChain` для просмотра текущего пути разрешения зависимостей.
+
+2. **Включите логирование**: Добавьте логирование в ваши провайдеры для трассировки разрешения зависимостей.
+
+3. **Упростите зависимости**: Разбейте сложные зависимости на более мелкие, управляемые части.
+
+4. **Используйте интерфейсы**: Абстрагируйте зависимости за интерфейсами для уменьшения связанности.
+
+## Заключение
+
+Обнаружение циклических зависимостей в CherryPick обеспечивает надежную защиту от бесконечных циклов и ошибок переполнения стека. Следуя лучшим практикам и используя подходящий уровень обнаружения для вашего случая использования, вы можете создавать надежные и поддерживаемые конфигурации внедрения зависимостей.

-If you use these, be sure to update your imports accordingly, e.g.:
-```dart
-import 'package:your_project/generated/app.inject.cherrypick.g.dart';
-```
-If not specified, generated files will appear next to your source files, as before.

-### Продвинутая настройка путей генерации кода
-
-В последних версиях генератора CherryPick добавлена поддержка гибкой настройки директорий и шаблонов имён файлов через `build.yaml`.
-
-Вы можете управлять и папкой назначения (через `output_dir`), и шаблоном имён (через `build_extensions`):
-
-```yaml
-targets:
-  $default:
-    builders:
-      cherrypick_generator|inject_generator:
-        options:
-          build_extensions:
-            '^lib/app.dart': ['lib/generated/app.inject.cherrypick.g.dart']
-          output_dir: lib/generated
-        generate_for:
-          - lib/**.dart
-      cherrypick_generator|module_generator:
-        options:
-          build_extensions:
-            '^lib/di/{{}}.dart': ['lib/generated/di/{{}}.module.cherrypick.g.dart']
-          output_dir: lib/generated
-        generate_for:
-          - lib/**.dart
-```
-
-- **output_dir**: Папка, куда будут складываться все сгенерированные файлы.
-- **build_extensions**: Полный контроль над именами итоговых файлов и подпапками.
-
-Если вы это используете, обязательно обновляйте импорты, например:
-```dart
-import 'package:your_project/generated/app.inject.cherrypick.g.dart';
-```
-Если не задать параметры, файлы будут сгенерированы рядом с исходными — как и раньше.

 ## Заключение
 
 **CherryPick** — это современное DI-решение для Dart и Flutter, сочетающее лаконичный API и расширенные возможности аннотирования и генерации кода. Гибкость Scopes, параметрические провайдеры, именованные биндинги и field-injection делают его особенно мощным как для небольших, так и для масштабных проектов.
