  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text("Onesignal Deeplink"),
        ),
        body: Home()
      ),

class Home extends StatefulWidget {
  const Home({Key? key}) : super(key: key);

  @override
  State<Home> createState() => _HomeState();
}

class _HomeState extends State<Home> {

  @override
  void initState() {
    super.initState();
    OneSignal.shared.setLogLevel(OSLogLevel.debug, OSLogLevel.none);
    OneSignal.shared.setAppId("82fc054e-08f0-4266-a9f5-d144716fcdae");

    OneSignal.shared.setNotificationOpenedHandler((openedResult) {
     var data =  openedResult.notification.additionalData!["Page"].toString();
     
     if(data == "Profile"){
       Navigator.push(context, MaterialPageRoute(builder: (context) => Profile()));

class Profile extends StatelessWidget {
  const Profile({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(title: const Text('Profile')),
