uni_links getInitialUri returns NULL iOS custom URL scheme

Hello guys! I have a set of custom URL schemes that are triggered with push notifications. Everything works fine with Android on all states (Open, Foreground/Background, Closed/Forced Quit). But not with iOS, which does not work when app is closed.

Everytime i close the app, force to open with a custom URL scheme, the app opens but the getInitialUri returns the uri as null, which is being called here:

main.dev

StreamSubscription uriSubscription;

  @override
  void initState() {
    super.initState();
    initPlatformState();
  }

  @override
  void dispose() {
    if (uriSubscription != null) {
      uriSubscription.cancel();
    }
    super.dispose();
  }

  Future<void> initPlatformState() async {
    debugPrint('com.fonixtelematics.app: initPlatformState');
    // if (!mounted) return;
    if (uriSubscription != null) {
      uriSubscription.cancel();
    }

    await pushService.init();
    uriSubscription = await URILinks().initStream();

    await URILinks().checkInitialURI();
  }

urilinks.dart

class URILinks {
  Future<StreamSubscription> initStream() async {
    return getUriLinksStream().listen(uriLinksHandler);
  }

  Future<void> checkInitialURI() async {
    debugPrint('com.fonixtelematics.app: checkInitialURI');
    return getInitialUri().then(uriLinksHandler).catchError((e) {
      debugPrint(
          'com.fonixtelematics.app: checkInitialURI ERROR ' + e.toString());
      navigatorKey.currentState.pushNamed(Routes.main);
    });
  }

  void uriLinksHandler(Uri uri) {
    debugPrint('com.fonixtelematics.app: uriLinksHandler ' + uri.toString());
    if (uri != null) {
      debugPrint('com.fonixtelematics.app: uriLinksHandler ' + uri.host);
    }
    if (uri != null && uri.host != null && uri.host.isNotEmpty) {
      switch (uri.host) {
        case 'auth':
          ...
          break;
        case 'alert':
          ...
          break;
        default:
          navigatorKey.currentState.pushNamed(Routes.main);
          break;
      }
    } else {
      throw (false);
    }
  }
}

Is anyone else having the same issue?
