Go Router (Flutter)- push the exact same route and refresh that route

With GoRouter, Is there a way to push the exact same route with a different parameter and make the page reload? I am thinking of something like Navigator.pushReplacement

I am using context.go('/my_page/?param={someID}') to push to MyPage (a stateful widget)

The initial push to this route works fine and I load up the page for the particular ID

I am trying to push this same route again (replace the route and reload with different ID) using context.go('/my_page/?param={differentID}'). My breakpoints are hitting the return statement in my GoRoute pageBuilder, and I also hit a breakpoint in MyPage.build. I see the new ID passed into this widget when breakpointing in the build.

But the Page does not rebuild visually (or break in initState - side note, init state is used to load up a couple cubits with the passed in ID - could the page being a stateful widget be the problem?)

Maintain state on the Material Page is false. Also, pushing different routes works just fine.

Is this a stateful widget issue (meaning relocate all of my cubit init calls)? or is there a different way to push the same route?

EDIT _____________

This question was specific to rebuilding the same route, but the greater problem I was working on was to infinitely drill into the same page over and over again, while maintaining the navigation stack.

I was using a state manager to hold a list of routes and trigger the navigation by using context.go() to replace the current route completely.

is there a way to dynamically nest routes with context.push() while maintaining the entire nav stack?

Another way to do that is by passing in extra param current timestamp. This way you can avoid the caching of the page

context.go(yourUrlHere, extra: DateTime.now().millisecondsSinceEpoch)

None of the solutions worked for me. I had a similar problem, I'm making a quiz app and wanted to have one code(bloc and view) for all the questionnaires. I have a QuizPage:

class QuizPage extends StatelessWidget {
 const QuizPage({super.key, required this.id});
 final String id;
 @override
 Widget build(BuildContext context) {
  return BlocProvider(
   create: (context) => QuizBloc(id: id)..add(GetQuizEvent(id: id)),
   child: const QuizView(),
  );
 }
}

I use the id to change the questionnaire. On my start game I used

context.go('/game/1.1');

But on the end of the 1.1 questionnaire the go('/game/1.2') didnt refreshed the page so the bloc didnt made a request for the new questionnaire. My solution was to use the UniqueKey() suggested by @Pablo Insua and passed a unique key to the QuizPage on the router like this:

GoRoute(
    path: '/game/:id',
    builder: (context, GoRouterState state) =>
        QuizPage(
            key: UniqueKey(),
            id: state.pathParameters['id'] ?? "",
        ),
  ),

I`m on go_router version ^14.0.2

I used the following method, reading the docs strings for context.go method helped a lot

context.pushReplacement(url);

So this problem will only show up if the route is nested (shell routes) and you have pushed a new route using context.pushNamed('route-name') or context.push('name').

You can simply await the child route to pop using the following code snippet.

onTap: () async {
  final bool? result = await context.push<bool>('/page2');
  if(result ?? false)...
  // TODO: here can be the refresh logic
}

This is mentioned in go_router docs. This won't reinitiate the page. . If you want to reinitiate the page every time the page shows up. The answer will be using UniqueKey() as suggested above. But this will cause issue with transition animation.

I think context.replace would accomplish what you are trying to do, since it should replace what is currently on the stack.

After some research, I have noticed that you can redirect to the same page by using pageKey: UniqueKey() in the definition of the GoRoute().

Example code from my project:

GoRoute(
    path: RoutePaths.serviceDetail.value,
    name: RouteNames.serviceDetail.value,
    pageBuilder: (context, state) {
        return CustomTransitionPage<void>(
            key: UniqueKey(),
            child: const ServiceDetailPage(),
            transitionsBuilder: (context, animation, secondaryAnimation, child) =>
            PageTransitions.subpageTransition(animation, child),
        );
    },
),
