当我不想使用堆栈来设置背景图像时，有没有办法将背景图像设置为Scaffold？

import 'package:flutter/material.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Background Image'),
        ),
        body: Container(
          decoration: BoxDecoration(
            image: DecorationImage(
              image: AssetImage('assets/background.jpg'),
              fit: BoxFit.cover,
            ),
          ),
          child: Center(
            child: Text(
              'Hello, World!',
              style: TextStyle(fontSize: 24),
            ),
          ),
        ),
      ),
    );
  }
}
