import 'package:flutter/material.dart';

return MaterialApp(

// changing the primarySwatch below to Colors.green and then invoke
// "hot reload" (press "r" in the console where you ran "flutter run",
// or simply save your changes to "hot reload" in a Flutter IDE).

Answer 1

I think you miss import file of HomeScreen at top of the main.dart.
HomeScreen class wasn't define in main.dart file as per your code.
Or maybe class name is something else. Check it again.

Answer 2

Chances are Home Screen is in another .dart file. You'll need to import this dart file into your main.dart for it to work. Super easy fix just add this part at the top
import 'package:flutter/material.dart';
import 'package:<projectname>/lib/<subfolder if you have one>/HomeScreen.dart'
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
// This widget is the root of your application.
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Food Delivery UI',
debugShowCheckedModeBanner: false,
theme: ThemeData(
scaffoldBackgroundColor: Colors.grey[50],
primaryColor: Colors.deepOrangeAccent,
primarySwatch: Colors.blue,
),
home: HomeScreen(),
);
}
}
