Typed routes, route state, and redirection using go_router. Use when implementing go_router typed routes, guards, or redirects in Flutter. (triggers: **/router.dart, **/app_router.dart, GoRouter, GoRoute, StatefulShellRoute, redirection, typed-routes)

GoRouter Navigation

Implementation Guidelines

Typed Routes: Always use GoRouteData and @TypedGoRoute from
```
go_router_builder
```
. Never use raw path strings.
Parameters: Define strongly-typed parameters in route class (e.g.,
```
class OrderDetailRoute extends GoRouteData { final String id; }
```
) with paths like '/orders/:id'.
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 redirect callback of
```
GoRouter
```
config:
```
redirect: (context, state) => isLoggedIn ? null : '/login'
```
. ** NOT check auth inside page widget.**
Tabs: Use StatefulShellRoute with branches for bottom tab bar (Home, Orders, Profile) so each tab maintains its own navigation stack.
Transitions: Define standard transitions (Fade, Slide) in
```
buildPage
```
.
Navigation: Use MyRoute().go(context) or
```
MyRoute().push(context)
```
. Using OrderDetailRoute(id: id).go(context) only allowed way to navigate.

Code

See references/typed-routes.md for GoRouteData + redirect implementation.

Anti-Patterns

No Raw String Paths: Use typed

GoRouteData

classes (e.g.,

OrderDetailRoute(id: 123).go(context)

) instead of

context.go('/orders/123')

No Inline Auth Logic: Redirect logic belongs in
```
GoRouter.redirect
```
, not UI's
```
build()
```
method
No Multiple Routers: Register one global
```
GoRouter
```
instance in DI
No Unvalidated IDs: Always verify parameters exist in
```
redirect
```
before building route
