When to Use This Agent

Building new Flutter applications
Implementing state management with Riverpod or Bloc
Setting up navigation with GoRouter
Integrating native platform features
Writing Flutter tests (widget, golden, integration)
Setting up Firebase with Flutter
Configuring build flavors and environments
Debugging Flutter rendering or performance issues

Instructions

When working on Flutter tasks:

Use Riverpod for new projects: Riverpod is the recommended state management for new Flutter projects. It is compile-safe, testable, and does not depend on BuildContext.
Composition over inheritance: Build complex widgets by composing smaller widgets. Avoid deep inheritance hierarchies.
const constructors: Use const constructors wherever possible to optimize widget rebuilds.
Separate business logic from UI: Keep widgets focused on display. Business logic belongs in providers/notifiers/blocs.
Test widgets: Write widget tests for all interactive components. Use golden tests for pixel-perfect UI verification.

Key Patterns

Riverpod State Management

// providers/auth_provider.dart
import 'package:riverpod_annotation/riverpod_annotation.dart';

part 'auth_provider.g.dart';

// Immutable state
class AuthState {
  final User? user;
  final bool isLoading;
  final String? error;

  const AuthState({this.user, this.isLoading = false, this.error});

  AuthState copyWith({User? user, bool? isLoading, String? error}) {
    return AuthState(
      user: user ?? this.user,
      isLoading: isLoading ?? this.isLoading,
      error: error,
    );
  }
}

// Notifier with code generation
@riverpod
class Auth extends _$Auth {
  @override
  AuthState build() => const AuthState();

    state = state.copyWith(isLoading: true, error: null);

      state = state.copyWith(user: user, isLoading: false);
    } catch (e) {
      state = state.copyWith(isLoading: false, error: e.toString());

  }

  Future<void> signOut() async {

  }
}

// Simple async provider
@riverpod

- Pattern matching (switch expressions, destructuring)
- Sealed classes for exhaustive matching
- Class modifiers (final, interface, base, mixin)
- Extension types
- Sound null safety

- Riverpod (providers, notifiers, async values)
- Bloc/Cubit (events, states, BlocBuilder)
- Provider (legacy, ChangeNotifier)
- flutter_hooks (useEffect, useState, useMemoized)
- State restoration

### Navigation

- GoRouter (declarative, deep links, redirects)
- auto_route (code generation, guards)
- Navigator 2.0 API
- Deep linking on iOS and Android
- URL-based routing for web

### Platform Integration

@riverpod
Future<User> userById(UserByIdRef ref, String userId) async {
  final repository = ref.read(userRepositoryProvider);

### GoRouter Navigation

```dart
// router/app_router.dart
import 'package:go_router/go_router.dart';

      final isAuthRoute = state.matchedLocation.startsWith('/auth');

      if (!isAuthenticated && !isAuthRoute) {
        return '/auth/login?redirect=${state.matchedLocation}';
      }
      if (isAuthenticated && isAuthRoute) {
        return state.uri.queryParameters['redirect'] ?? '/';
      }
      return null;

### Widget with Riverpod Consumer

```dart

import 'package:flutter/material.dart';
import 'package:flutter_riverpod/flutter_riverpod.dart';

class PostsScreen extends ConsumerWidget {
  const PostsScreen({super.key});

1Lisez la source et confirmez entrées, résultats, dépendances et permissions.
2Demandez un plan à l’agent. Approuvez la configuration et les coûts avant un test isolé.
3Vérifiez résultats et fichiers modifiés. Signalez uniquement ce qui a été exécuté et conservez la révision source.

Vérifiez les dépendances, clés API et frais externes dans la source. Un dépôt public ne rend pas tous les services gratuits.
