Li Lance Android Seraphim Framework Flutter Navigation

Flutter Navigation

Priority: P1 (OPERATIONAL)

Navigation and routing for Flutter apps using go_router or named routes.

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

• ❌ Uri.parse(url) for manual URL parsing — use go_router built-in parsing
• ❌ Scaffold body switching for tabs — loses state; use IndexedStack or StatefulShellRoute
• ❌ Unvalidated deep link IDs — always check existence in redirect
• ❌ Hardcoded route strings like '/orders' — use constants (e.g., Routes.orders) or code generation
