List<Widget> makeList() {
  List<Widget> result = List();
  for(int i=0;i<100;i++){

class _MyHomePageState extends State<MyHomePage> {

  @override
  Widget build(BuildContext context) {
    //返回一个列表
    return Scaffold(
      appBar: AppBar(title: Text(widget.title)),
      body: new Container(
        child: new ListView(
          children: makeList(),
