🐦 Mobile Flutter

Flutter/Dart best practices ve performance optimization.

📁 1. Proje Yapısı (Feature-First)

🧩 2. Widget Best Practices

// ✅ const constructor kullan
class MyButton extends StatelessWidget {
  const MyButton({super.key, required this.onPressed});
  final VoidCallback onPressed;

  @override
  Widget build(BuildContext context) {
    return ElevatedButton(onPressed: onPressed, child: Text('Click'));
  }
}

// ✅ const widget'ları işaretle
const SizedBox(height: 16),

📦 3. State (Riverpod)

final authProvider = StateNotifierProvider<AuthNotifier, AuthState>((ref) {
  return AuthNotifier(ref.watch(authRepositoryProvider));
});

class AuthNotifier extends StateNotifier<AuthState> {
  AuthNotifier(this._repo) : super(const AuthState());
  
  Future<void> login(String email, String password) async {
    state = state.copyWith(isLoading: true);
    final user = await _repo.login(email, password);
    state = state.copyWith(user: user, isLoading: false);
  }
}

⚡ 4. Performance

// ✅ ListView.builder (lazy loading)
ListView.builder(
  itemCount: items.length,
  itemBuilder: (context, index) => ItemCard(item: items[index]),
)

// ✅ RepaintBoundary
RepaintBoundary(child: ExpensiveWidget())

// ✅ Isolate for CPU-heavy
final result = await compute(parseUsers, jsonString);

🔐 5. Secure Storage

import 'package:flutter_secure_storage/flutter_secure_storage.dart';

final storage = FlutterSecureStorage();
await storage.write(key: 'token', value: token);
final token = await storage.read(key: 'token');

📱 6. Responsive

// MediaQuery
final isTablet = MediaQuery.of(context).size.width > 600;

// LayoutBuilder
LayoutBuilder(
  builder: (context, constraints) {
    return constraints.maxWidth > 600 ? WideLayout() : NarrowLayout();
  },
)

🔄 Workflow

Kaynak: Flutter Engineering Best Practices & Riverpod Architecture

Aşama 1: Architecture Setup

• Layering: Feature-First yapısını kur (Presentation, Domain, Data).
• State Management: Riverpod NotifierProvider ve Code Generation (@riverpod) kullan.
• Routing: GoRouter ile type-safe navigasyon ve deep linking yapılandır.

Aşama 2: Implementation

• UI: const constructorları kullanarak rebuild'leri minimize et.
• Network: Dio ve Retrofit ile API katmanını (Interceptor, Error Handling) yaz.
• Storage: Hassas veriler için flutter_secure_storage, cache için Isar veya Hive kullan.

Aşama 3: Release & Quality

• Testing: Unit, Widget ve Integration testlerini (Golden Tests dahir) yaz.
• Performance: DevTools ile "Jank" (kare atlama) analizi yap (Shader compilation warm-up).
• CI/CD: Fastlane ile otomatik build ve store upload süreçlerini kur.
