I have a simple FutureProvider that holds a bool value:

@riverpod
Future<bool> isAuthenticated(IsAuthenticatedRef ref) async {
  // Some async logic here
  return await getAuthState();
}

I use auto_route package which provides the reevaluateListenable param in the router config to allow re-evaluate the route stack and re-call route guards when some value changes:

MaterialApp.router(
  routerConfig: _appRouter.config(
    reevaluateListenable: authProvider,
  ),
);

I need to perform re-evaluation when authentication state changes, the problem is that reevaluateListenable requires a Listenable, but FutureProvider does not implement it.

I’ve tried implementing authChangeNotifierProvider:

class AuthChangeNotifier extends ChangeNotifier {
  bool isAuthenticated = false;
  final AutoDisposeChangeNotifierProviderRef <AuthChangeNotifier> ref;

  AuthChangeNotifier({required this.ref}) {
    ref.listen(tokenPairProvider, (_, newValue) {
      isAuthenticated = newValue.when(
          data: (data) => data.isAuthenticated,
          error: (_, __) => false,
          loading: () => false);
      notifyListeners();
    });
  }
}

final authChangeNotifierProvider = ChangeNotifierProvider.autoDispose<AuthChangeNotifier>((ref) {
  return AuthChangeNotifier(ref: ref);
});

This way I can pass listenable to the router config, but then I have no idea how to access the actual value inside the route guard. What would be the best way to achieve this?
