Flutter GoRouter Navigation

GoRouter Navigation

Priority: P0 (CRITICAL)

Type-safe deep linking and routing system using go_router and go_router_builder.

Structure

core/router/
├── app_router.dart # Router configuration
└── routes.dart # Typed route definitions (GoRouteData)

Implementation Guidelines

• Typed Routes: Always use GoRouteData from go_router_builder. Never use raw path strings.
• Root Router: One global GoRouter instance registered in DI.
• Sub-Routes: Nest related routes using TypedGoRoute and children lists.
• Redirection: Handle Auth (Login check) in the redirect property of the GoRouter config.
• Parameters: Use @TypedGoRoute to define paths with :id parameters.
• Transitions: Define standard transitions (Fade, Slide) in buildPage.
• Navigation: Use MyRoute().go(context) or MyRoute().push(context).

Code

// Route Definition
@TypedGoRoute<HomeRoute>(path: '/')
class HomeRoute extends GoRouteData {
  @override
  Widget build(context, state) => const HomePage();
}

// Router Config
final router = GoRouter(
  routes: $appRoutes,
  redirect: (context, state) {
    if (notAuthenticated) return '/login';
    return null;
  },
);
