Provider not found exception

Question

We have a cover page that has two buttons. One leads to the Contractor's login and registration page, and the other button leads to Hirer login and Registration. In order to check whether a user is already logged into the app, we are using a wrapper.dart which contains the following code:

  @override
  Widget build(BuildContext context) {
    final user = Provider.of<User>(context);
    print(user);
    enter code here
    if (user == null) {
      return Authenticate();
    } else {
      return Home();
    }
  }
}

This is our code snippet for contractorwrapper. We have a similar one for hirerWrapper as well. We are getting this error:

/flutter (23750): ══╡ EXCEPTION CAUGHT BY WIDGETS LIBRARY ╞═══════════════════════════════════════════════════════════ I/flutter (23750): The following ProviderNotFoundException was thrown building ContractorWrapper(dirty): I/flutter (23750): Error: Could not find the correct Provider above this ContractorWrapper Widget

Solution

   class MyApp extends StatelessWidget {
    @override
   Widget build(BuildContext context) {
    return   MultiProvider(
    providers: [
    ChangeNotifierProvider(
  create: (context) => User())],
  child: MaterialApp(
    home: Scaffold(
        appBar: AppBar(
          backgroundColor: Colors.blue,
          title: Text("First appbar"),
        ),
        body: Text("content")),
       ),
     );
 }
   }
