class _MyHomePageState extends State<MyHomePage>{
@override
Widget build(BuildContext context){
return new Scaffold(appBar: new AppBar(
title: new Text(Translations.of(context).text('app_title')), // 试着使用下翻译库
),
body: new GestureDetector(
child:new Container(
child: new Text(Translations.of(context).text('main_title'),style: new TextStyle(fontSize: 17,color: Colors.black),)
