Flutter中经过循环渲染组件

class ContactsState extends State<Contacts>{ List formList; initState() { super.initState(); formList = [ {"icon": Icon(Icons.alarm),"title": '车牌号'}, {"icon": Icon(Icons.album),"title": '全部人'}, {"icon": Icon(Icons.archive),"title": '号牌颜色'}, ]; } Widget buildGrid() { List<Widget> tiles = [];//先建一个数组用于存放循环生成的widget
        Widget content; //单独一个widget组件，用于返回须要生成的内容widget
        for(var item in formList) { tiles.add( new Row( children: <Widget>[ new Icon(Icons.alarm), new Text(item['title']), ] ) ); } content = new Column( children: tiles //重点在这里，由于用编辑器写Column生成的children后面会跟一个<Widget>[]， //此时若是咱们直接把生成的tiles放在<Widget>[]中是会报一个类型不匹配的错误，把<Widget>[]删了就能够了
 ); return content; } @override Widget build(BuildContext context) { return Scaffold( appBar: AppBar( title: Text('循环渲染组件案例'), ), body: new Center( child: buildGrid(), ) ); } }
