基本 List

显示数据列表是移动应用程序常见的需求。Flutter包含的ListView Widget，使列表变得轻而易举！

创建一个ListView

使用标准ListView构造函数非常适合仅包含少量条目的列表。我们使用内置的ListTile Widget来作为列表项。

new ListView(
  children: <Widget>[
    new ListTile(
      leading: new Icon(Icons.map),
      title: new Text('Maps'),
    ),
    new ListTile(
      leading: new Icon(Icons.photo_album),
      title: new Text('Album'),
    ),
    new ListTile(
      leading: new Icon(Icons.phone),
      title: new Text('Phone'),
    ),
  ],
);

完整的例子

import 'package:flutter/material.dart';
void main() => runApp(new MyApp());
class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final title = 'Basic List';
    return new MaterialApp(
      title: title,
      home: new Scaffold(
        appBar: new AppBar(
          title: new Text(title),
        ),
        body: new ListView(
          children: <Widget>[
            new ListTile(
              leading: new Icon(Icons.map),
              title: new Text('Map'),
            ),
            new ListTile(
              leading: new Icon(Icons.photo),
              title: new Text('Album'),
            ),
            new ListTile(
              leading: new Icon(Icons.phone),
              title: new Text('Phone'),
            ),
          ],
        ),
      ),
    );
  }
}
