Direct push notification to specific screen when app is terminated

Question

I want the user to land to a specific screen when a notification is tapped from a terminated state. I know that the getInitialMessage() handles notifications from terminated state but it doesn't seem to navigate to the screen I want.

Here's the code:

AndroidNotificationChannel channel;
FlutterLocalNotificationsPlugin flutterLocalNotificationsPlugin;
 final GlobalKey<NavigatorState> navigatorKey = GlobalKey(debugLabel: "Main Navigator");
 Future<void> _firebaseMessagingBackgroundHandler(RemoteMessage message) async {
    RemoteNotification notification = message.notification;
   flutterLocalNotificationsPlugin.show(
            notification.hashCode,
            notification.title,
            notification.body,
            NotificationDetails(
              android: AndroidNotificationDetails(
                channel.id,
                channel.name,
                channel.description,
                icon: '@drawable/splash',
                playSound: true
              ),
            ));
            navigatorKey.currentState
                      .push(MaterialPageRoute(builder: (_) => OrdersScreen()));
}
Future<void> main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp();
  FirebaseMessaging.onBackgroundMessage(_firebaseMessagingBackgroundHandler);
    channel = const AndroidNotificationChannel(
      'high_importance_channel', // id
      'High Importance Notifications', // title
      'This channel is used for important notifications.', // description
      importance: Importance.high,
    );
    flutterLocalNotificationsPlugin = FlutterLocalNotificationsPlugin();
    await flutterLocalNotificationsPlugin
        .resolvePlatformSpecificImplementation<
            AndroidFlutterLocalNotificationsPlugin>()
            ?.createNotificationChannel(channel);
    
     
      runApp(MyApp());
    }
    class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  void initState() {
         var initializationSettingsAndroid  = AndroidInitializationSettings('@drawable/splash');
    var initializationSettings = InitializationSettings(android:initializationSettingsAndroid);
    flutterLocalNotificationsPlugin.initialize(initializationSettings);
     FirebaseMessaging.instance
        .getInitialMessage()
        .then((RemoteMessage message) {
          print('Inside get initial message'); 
      if (message != null) {
        print('Inside message not null'); 
          navigatorKey.currentState
                       .push(MaterialPageRoute(builder: (_) => OrdersScreen()));
      }
    });
}
}

As you can see, I want to navigate to ordersscreen but I instead land on the landing page. What am I missing? It works fine when the notification is tapped from background state or foreground state, but not from terminated state.
