  }
}

2. Now, in main.dart, replace ImmutableWidget with BasicScreen. Hit  the save button to hot reload and your simulator screen should be completely white:

import 'package:flutter/material.dart';
import './basic_screen.dart';

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

class StaticApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: BasicScreen(),
