It works when I try the package normally with a button, but it doesn't work from my own class.

Hello, as I mentioned, I checked the package with a button to try it, normally it works fine with the context of that widget, but when I try to run it in my Notification Handler class. I get the message from the top like the usage in this package when it is open. I think the problem is the context in the messaging page and the contex in my class are different so I can't see anything how can I solve this.

My Notification Handler

class NotificationHandler {
  String userId;

  FirebaseMessaging _fcm = FirebaseMessaging();

  static final NotificationHandler _singelton = NotificationHandler._internal();

  factory NotificationHandler() {
    return _singelton;
  }

  NotificationHandler._internal();

  BuildContext myContext;

  initializeFCMNotification(BuildContext context) async {


    myContext = context;

    final _tumKullanicilarViewModel =
    Provider.of<AllUserViewModel>(context, listen: false);
    var initializationSettingsAndroid = AndroidInitializationSettings("yeni");
    var initializatioonSettingsIOS = IOSInitializationSettings(
        onDidReceiveLocalNotification: onDidReceiveLocalNotification);
    var initializationSettings = InitializationSettings(
        initializationSettingsAndroid, initializatioonSettingsIOS);
    flutterLocalNotificationsPlugin.initialize(initializationSettings,
        onSelectNotification: onSelectNotification);
    //_fcm.subscribeToTopic("all");
    // String token= await _fcm.getToken();
    //  print("token : $token");
    _fcm.onTokenRefresh.listen((newToken) async {
      FirebaseUser _currentUser = await FirebaseAuth.instance.currentUser();
      Firestore.instance
          .document("tokens/" + _currentUser.uid)
          .setData({"token": newToken});
    });

    _fcm.configure(
      onMessage: (Map<String, dynamic> message) async {
        print("onmessage ");

        var notificationData = message['notification'];

        //If currently user is there, do not show notification
        var data = message['data'];
        var view;
        if (data != null) {
          view = data['view'];
          print(message['data']);
        }
        print("root gosterirmi //*/0" +
            MyNavigatorObserver.routeStack.toString());

        if (MyNavigatorObserver.routeStack.last == message['data']['view'] &&
            _tumKullanicilarViewModel.tiklaninanUserID ==
                message['data']['gonderenUserID']) {
          print("chat page deyiz");

          //show in app notification 
        } if( _tumKullanicilarViewModel.tiklaninanUserID !=
            message['data']['gonderenUserID']) {
          print("baska birinin sayfasındayım");

         showFlash(
            context: context,
            duration: const Duration(milliseconds: 1500),
            persistent: false,
            builder: (_, controller) {
              return Flash(
                backgroundGradient: RadialGradient(
                  colors: [Colors.red, Colors.white],
                  center: Alignment.topLeft,
                  radius: 2,
                ),
                controller: controller,
                backgroundColor: Colors.white,
                brightness: Brightness.light,
                boxShadows: [BoxShadow(blurRadius: 4)],
                barrierBlur: 2.0,
                barrierColor: Colors.black38,
                barrierDismissible: true,
                style: FlashStyle.floating,
                position: FlashPosition.top,
                child: FlashBar(
                  title: Text('Title'),
                  message: Text('Hello world!'),
                  showProgressIndicator: true,
                  progressIndicatorValueColor:
                  AlwaysStoppedAnimation<Color>(Colors.green),
                  primaryAction: FlatButton(
                    onPressed: () => controller.dismiss(),
                    child: Text('Kapat',
                        style: TextStyle(color: Colors.red, fontSize: 18)),
                  ),
                ),
              );
            },
          );

          

         /* PdyALertDialog(
            baslik: message['data']['title'],
            kapatAlert: "tamam",
            kapatAlertColor: Colors.blue, //89hjb5Qaqg4rYTD48cbjo5kusx2//
            icerik: message['data']['message'],
          ).goster(context);*/
        }

        if (_tumKullanicilarViewModel.tiklaninanUserID ==
            message['data']['gonderenUserID']) {
          print("chat page deyiz ve konustugumuz userdayız");
        } else {
          print("konustugumuz userda değiliiz");
        }
      },
      onLaunch: (Map<String, dynamic> message) async {
        print("onlaunch tetiklendi");
      },
      onResume: (Map<String, dynamic> message) async {
        print("onresume tetiklendi");
      },
      onBackgroundMessage: myBackgroundMessageHandler,
    );
  }}

My Overlay

 Navigator.of(context, rootNavigator: true).push(
          MaterialPageRoute(
            settings:
                RouteSettings(arguments: oankiUser.userID, name: "/chatpage"),
            builder: (context) {
              return ChangeNotifierProvider(
                create: (context) => ChatViewModel(
                  chatUser: oankiUser,
                  currentUser: _userModel.user,
                ),
                child: Overlay(
                  initialEntries: [
                    OverlayEntry(builder: (context) {
                      return KonusmaPage();
                    })
                  ],
                ),
              );
            },
          ),
        );

One more question, in this package, dialogs are shown according to the context value of the page required to do them?

I solved the problem animation color would accept two different colors in the widget, but did not accept it in a separate class. Giving one color solved the problem.
