Could not find the correct Provider above this ListView Widget-CodePudding

Error: Could not find the correct Provider above this StudentsList Widget

Trying to access the data from the provider package but stuck with this error I tried adding ChangeNotifierProvider to the main dart file but still getting the same error.

Home Screen

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

  @override
  Widget build(BuildContext context) {
    ChangeNotifierProvider(
      create: (_) => Students(),
    );
    return Scaffold(
      appBar: AppBar(
        title: const Text("Home"),
      ),
      body: StudentsList(),
    );
  }
}

StudentsList File

class StudentsList extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    var studentDataList = Provider.of<Students>(context).studentsList;
    return ListView.builder(
      itemBuilder: (ctx, item) {
        return ListTile(...);
  }
}

Moving Provider up to a parent, MaterialApp context, allows both Screen A and B to inherit its state/context.

provider(MaterialApp)

Screen A Screen B

Its just a syntax error that is creating this issue. Edited the code in the home screen to :

Widget build(BuildContext context) {
    return ChangeNotifierProvider(
      create: (_) => Students(),
      child: Scaffold(
        appBar: AppBar(
          title: const Text("Home"),
        ),
        body: StudentsList(),
      ),
    );
  }
}
