name: flutter-navigation description: Implement navigation patterns with go_router, deep linking, and named routes in Flutter. Use when building navigation, deep linking, or routing. metadata: triggers: files: - '/*_route.dart' - '/*_router.dart' - '**/main.dart' keywords: - Navigator - GoRouter - routes - deep link - go_router - AutoRoute

Flutter Navigation

Priority: P1 (OPERATIONAL)

Implementation Workflow

1. Choose router — Use go_router for modern, declarative routing.
2. Define routes — Use constants or code generation for route paths; never hardcode strings.
3. Configure deep links — Set up AndroidManifest.xml and Info.plist for URL schemes.
4. Validate parameters — Check parameters in redirect logic before navigation.
5. Preserve tab state — Use StatefulShellRoute or IndexedStack for bottom navigation.

Route Configuration Example

See implementation examples for GoRouter configuration with parameter validation and redirects.

Routing Patterns & Examples

Anti-Patterns

• No Manual URL Parsing: Use go_router built-in parsing instead of Uri.parse(url)
• No Manual Tab State Management: Use IndexedStack or StatefulShellRoute to preserve state
• No Unvalidated Deep Link IDs: Always check existence in redirect
• No Hardcoded Route Strings: Use constants (e.g., Routes.orders) or code-gen instead of '/orders'
