## 🔴 SECTION 1 : TÂCHES CRITIQUES

### 1.1 Configuration Multi-Environnements

#### Packages requis
```yaml
dependencies:
  flutter_dotenv: ^5.1.0
  
dev_dependencies:
  flutter_flavorizr: ^2.2.3
```

#### Structure des fichiers
```
.env.dev
.env.staging
.env.production

lib/config/
  ├── env_config.dart
  ├── app_config.dart
  └── flavor_config.dart
```

#### Exemple env_config.dart
```dart
class EnvConfig {
  static const String keycloakUrl = String.fromEnvironment(
    'KEYCLOAK_URL',
    defaultValue: 'http://192.168.1.11:8180',
  );
  
  static const String apiUrl = String.fromEnvironment(
    'API_URL',
    defaultValue: 'http://192.168.1.11:8080',
  );
  
  static const String environment = String.fromEnvironment(
    'ENVIRONMENT',
    defaultValue: 'dev',
  );
}
```

#### Configuration Android flavors (build.gradle)
```gradle
android {
    flavorDimensions "environment"
    
    productFlavors {
        dev {
            dimension "environment"
            applicationIdSuffix ".dev"
            versionNameSuffix "-dev"
            resValue "string", "app_name", "UnionFlow Dev"
        }
        
        staging {
            dimension "environment"
            applicationIdSuffix ".staging"
            versionNameSuffix "-staging"
            resValue "string", "app_name", "UnionFlow Staging"
        }
        
        prod {
            dimension "environment"
            resValue "string", "app_name", "UnionFlow"
        }
    }
}
```

#### Scripts de build
```bash
# build_dev.sh
flutter build apk --flavor dev --dart-define=ENVIRONMENT=dev

# build_prod.sh
flutter build apk --flavor prod --dart-define=ENVIRONMENT=production --release
```

```

      FlutterError.presentError(details);
      _logError(details.exception, details.stack);
      _reportToCrashlytics(details.exception, details.stack);
    };
    
    // Erreurs Dart asynchrones
    PlatformDispatcher.instance.onError = (error, stack) {
      _logError(error, stack);
      _reportToCrashlytics(error, stack);
      return true;
    };
  }
  
  static void _logError(Object error, StackTrace? stack) {
    debugPrint('❌ Error: $error');
    debugPrint('Stack trace: $stack');
    LoggerService.error(error.toString(), stackTrace: stack);
  }
  
  static void _reportToCrashlytics(Object error, StackTrace? stack) {
    if (EnvConfig.environment != 'dev') {
      FirebaseCrashlytics.instance.recordError(error, stack);
    }
  }
}
```

#### app_exception.dart
```dart
abstract class AppException implements Exception {
  final String message;
  final String? code;
  final dynamic originalError;
  
  const AppException(this.message, {this.code, this.originalError});
}

class NetworkException extends AppException {
  const NetworkException(String message, {String? code}) 
      : super(message, code: code);
}

class AuthenticationException extends AppException {
  const AuthenticationException(String message) : super(message);

    _logs.add(entry);
    if (_logs.length > _maxLogs) {
      _logs.removeAt(0);
    }
    
    // Console output

    if (level == null) return List.unmodifiable(_logs);
    return _logs.where((log) => log.level == level).toList();
  }
  
  static Future<void> exportLogs() async {
    final json = jsonEncode(_logs.map((e) => e.toJson()).toList());
    // Implémenter export vers fichier ou partage
  }
}

class LogEntry {
  final LogLevel level;
  final String message;
  final DateTime timestamp;
  final Object? error;
  final StackTrace? stackTrace;
  final Map<String, dynamic>? data;

### 1.6 Architecture DI Complète

#### Structure DI par module
```
lib/features/members/di/
  └── members_di.dart

lib/features/events/di/
  └── events_di.dart

lib/features/reports/di/
  └── reports_di.dart
```

#### Exemple members_di.dart
```dart
class MembersDI {
  static final GetIt _getIt = GetIt.instance;
  
  static void registerDependencies() {
    // Repository
    _getIt.registerLazySingleton<MemberRepository>(
      () => MemberRepositoryImpl(_getIt<Dio>()),
    );
    
    // Service
    _getIt.registerLazySingleton<MemberService>(
      () => MemberService(_getIt<MemberRepository>()),
    );
    
    // BLoC (Factory pour créer nouvelle instance à chaque fois)
    _getIt.registerFactory<MembersBloc>(
      () => MembersBloc(_getIt<MemberService>()),
    );
  }
  
  static void unregisterDependencies() {
    _getIt.unregister<MembersBloc>();
    _getIt.unregister<MemberService>();
    _getIt.unregister<MemberRepository>();
  }
}
```

#### app_di.dart mis à jour
```dart
class AppDI {
  static Future<void> initialize() async {
    await _setupNetworking();
    await _setupModules();
  }
  
  static Future<void> _setupModules() async {
    OrganisationsDI.registerDependencies();
    MembersDI.registerDependencies();
    EventsDI.registerDependencies();
    ReportsDI.registerDependencies();
    NotificationsDI.registerDependencies();

### 1.7 Standardisation BLoC Pattern

#### Template BLoC standard
```dart
// Events
abstract class MembersEvent extends Equatable {
  const MembersEvent();
  @override
  List<Object?> get props => [];
}

class LoadMembers extends MembersEvent {
  final int page;
  final int size;
  const LoadMembers({this.page = 0, this.size = 20});
  @override
  List<Object?> get props => [page, size];
}

// States
abstract class MembersState extends Equatable {
  const MembersState();
  @override
  List<Object?> get props => [];
}

class MembersInitial extends MembersState {
  const MembersInitial();
}

class MembersLoading extends MembersState {
  const MembersLoading();
}

class MembersLoaded extends MembersState {
  final List<Member> members;
  final bool hasMore;
  final int currentPage;
  
  const MembersLoaded({
    required this.members,
    this.hasMore = false,
    this.currentPage = 0,
  });
  
  @override
  List<Object?> get props => [members, hasMore, currentPage];
}

class MembersError extends MembersState {
  final String message;
  final AppException? exception;
  
  const MembersError(this.message, {this.exception});
  
  @override
  List<Object?> get props => [message, exception];
}

// BLoC
class MembersBloc extends Bloc<MembersEvent, MembersState> {
  final MemberService _service;
  
  MembersBloc(this._service) : super(const MembersInitial()) {
    on<LoadMembers>(_onLoadMembers);
  }
  
  Future<void> _onLoadMembers(
    LoadMembers event,
    Emitter<MembersState> emit,
  ) async {
    try {
      emit(const MembersLoading());
      
      final members = await _service.getMembers(
        page: event.page,
        size: event.size,
      );
      
      emit(MembersLoaded(
        members: members,
        hasMore: members.length >= event.size,
        currentPage: event.page,
      ));
    } on NetworkException catch (e) {
      emit(MembersError('Erreur réseau: ${e.message}', exception: e));
    } catch (e) {
      emit(MembersError('Erreur inattendue: $e'));
