Flutter:如何在ListView中添加更多按钮

import 'package:flutter/material.dart';

Widget buildListItem() {
  return ListTile(
    title: Text('列表项'),
    trailing: RaisedButton(
      child: Text('更多'),
      onPressed: () {
        // 在这里处理按钮的点击事件
      },
    ),
  );
}

Widget buildListView() {
  return ListView.builder(
    itemCount: 10, // 列表项的数量
    itemBuilder: (BuildContext context, int index) {
      return buildListItem();
    },
  );
}

Widget build(BuildContext context) {
  return Scaffold(
    appBar: AppBar(
      title: Text('Flutter ListView示例'),
    ),
    body: buildListView(),
  );
}
