如何为flutter中的ListView设置FloatingActionButton的位置？

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('ListView with FloatingActionButton'),
        ),
        body: ListView.builder(
          itemCount: 10,
          itemBuilder: (BuildContext context, int index) {
            return ListTile(
              title: Text('Item $index'),
            );
          },
        ),
        floatingActionButton: FloatingActionButton(
          onPressed: () {
            // 按钮点击事件
          },
          child: Icon(Icons.add),
          // 设置按钮位置
          // 通过修改这里的alignment属性来调整按钮的位置
          // 可选值包括：Alignment.center、Alignment.bottomCenter、Alignment.bottomLeft、Alignment.bottomRight等
          alignment: Alignment.bottomRight,
        ),
      ),
    );
  }
}
