## Navigation

### GoRouter (Recommended)

```dart
final router = GoRouter(
  initialLocation: '/',
  routes: [
    GoRoute(
      path: '/',
      builder: (context, state) => const HomeScreen(),
      routes: [
        GoRoute(
          path: 'market/:id',
          builder: (context, state) {
            final id = state.pathParameters['id']!;
            return MarketDetailScreen(marketId: id);
          },
        ),
      ],
    ),
    GoRoute(
      path: '/profile',
      builder: (context, state) => const ProfileScreen(),
    ),
  ],
  errorBuilder: (context, state) => ErrorScreen(error: state.error),
);

// Usage
class MyApp extends StatelessWidget {
  const MyApp({super.key});
  
  @override
  Widget build(BuildContext context) {
    return MaterialApp.router(
      routerConfig: router,
    );
  }
}

// Navigate
context.go('/market/123');
context.push('/profile');
context.pop();
```
