Flutter:如何在容器内的ListView上添加文本行

import 'package:flutter/material.dart';

Widget buildListItem(String text) {
  return ListTile(
    title: Text(text),
  );
}

ListView buildListView() {
  return ListView(
    children: <Widget>[
      buildListItem('文本行1'),
      buildListItem('文本行2'),
      buildListItem('文本行3'),
      // 可以继续添加更多的文本行
    ],
  );
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: Text('Flutter应用'),
        ),
        body: buildListView(),
      ),
    );
  }
}
