Flutter go_router 根本不导航？

Question

I implemented go_router into my app today. I don't really have much to say except that it just does not navigate if I call context.go('/main') . No error, nothing.

This is my GoRouter Object in the MaterialApp Widget in the main.dart file:

GoRouter(
        redirect: (BuildContext context, GoRouterState state) {
          if (isAlreadyLoggedIn == null) return '/loading';
          if (isAlreadyLoggedIn!) {
            return '/main';
          } else {
            return '/';
          }
        },
        routes: [
          GoRoute(
              path: '/',
              builder: (context, state) => const LoginPage(title: 'Login')),
          GoRoute(
              path: '/main',
              builder: (context, state) =>
                  const MainPage(title: 'Dashboard')),
          GoRoute(
            path: '/loading',
            builder: (context, state) => const LoadingPage(),
          )
        ]));

If have an Auth Flow, which checks if the User was already logged In. If yes, the User is redirected to the main Page (works here properly). If not, the User needs to login. If succeeded, I want to navigate to main. And here nothing happens.

Thank you!

you will need to implement refreshListenable on GoRouter , this field will notify to GoRouter when isAlreadyLoggedIn changed. You can read more at here
