Hot reload was rejected: Const class cannot become non-const

I want to remove debug banner and top bar with battery level and wifi icons. but it displays an error. where should I correct my code? here I have included my main. dart and home. dart.

error>> Hot reload was rejected: Const class cannot become non-const: Library:'package:groceries_app/main.dart' Class: MyApp. Try performing a hot restart instead.

main.dart

import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
import 'package:groceries_app/home.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override

  Widget build(BuildContext context) {
    SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(
        statusBarColor: Colors.transparent));
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      title: 'Groceries App',
      home: HomePage(),
    );
  }
}

home.dart

import 'package:flutter/material.dart';

class HomePage extends StatefulWidget{
  @override
  _HomePageState createState() => _HomePageState();}

class _HomePageState extends State <HomePage>{
  @override
  Widget build (BuildContext context){
    return Scaffold(
      body: Center(
        child: Text("Home Page"),
      ),
    );
  }
}
