name: flutter-auto-route-navigation description: Implement typed routing, nested routes, and auth guards using auto_route in Flutter. Use when the task explicitly uses auto_route or its generated router; defer generic deep-link setup and other routing libraries. metadata: triggers: files: - '/router.dart' - '/app_router.dart' keywords: - AutoRoute - AutoRouter - router - guards - navigate - push

AutoRoute Navigation

Priority: P1 (HIGH)

└── app_router.gr.dart    # Generated routes

Implementation Workflow

1. Annotate pages — Mark all screen/page widgets with @RoutePage().
2. Configure router — Extend _$AppRouter and annotate with @AutoRouterConfig.
3. Navigate with types — Use generated route classes (e.g., HomeRoute()). Never use strings.
4. Add guards — Implement AutoRouteGuard for authentication/authorization logic.
5. Handle parameters — Constructors of @RoutePage widgets automatically become route parameters.
6. Prefer declarative calls — Use context.pushRoute() or context.replaceRoute().

Nested Routes & Tabs

Use children in AutoRoute for tabs. Pass children parameter to define initial active sub-route.

See implementation examples for nested route navigation and router configuration patterns.

Reference & Examples

Anti-Patterns

• No string-based navigation: Use generated typed route classes (e.g., OrderDetailRoute(id: 123)).
• No protected screen without AutoRouteGuard: Every protected route must declare guard; don't rely on UI-level checks.
• No navigation calls from BLoC: Emit state and let Presentation layer navigate.
