Using GoRouter. I tried adding the navigatorKey, but that didn't work

final navigatorKey = GlobalKey<NavigatorState>();

final app_router = GoRouter(
  navigatorKey: navigatorKey,
  initialLocation: '/login',
  routes: [
    GoRoute(
      path: '/debug',
      builder: (context, state) => DebugScreen(),
    ),
    GoRoute(
      path: '/login',
      builder: (context, state) => LoginScreen(),
    ),
    GoRoute(
      path: '/',
      builder: (context, state) => HomeScreen(),
    ),
  ],
);
