  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  final AppLinks _appLinks = AppLinks();
  StreamSubscription<Uri>? _linkSubscription;
  late final AuthCubit _authCubit; // 👈 make it accessible

  final authenticationNotifierProvider =
  NotifierProvider<AuthenticationNotifier, AuthenticationState>(
    AuthenticationNotifier.new,
  );
  @override
  void initState() {
    // TODO: implement initState
    super.initState();
    _authCubit = AuthCubit( // 👈 initialize it here
      clientId: "xxxxxxxxxxxxxxxx",
      redirectUri: "xxxxxxxxxxxxxxxx",
      scope: "openid profile email offline_access",
    );
    initDeepLinks();
  }

  Future<void> initDeepLinks() async {
    CupertinoActivityIndicator(animating: true,);
    // Handle links
    _linkSubscription = AppLinks().uriLinkStream.listen((uri) async{
      debugPrint('onAppLink: $uri');
      Uri.parse(uri.toString());
      if (uri.toString().contains('vsauth/?code')) {
           // handle navigation and otherthings
        Map<String, dynamic>? userData = await  _authCubit?.getAuthrorisationCode(uri);
        //In userData you will get all return response from facebook, google and azure
        debugPrint("User data is in main project ${userData}");
        CupertinoActivityIndicator(animating: false,);
      }
      //openAppLink(uri);
