class _DemoPageState extends State<DemoPage> {

  @override
  Widget build(BuildContext context) {
    return Container(
      height: 400.0,
      child: PageView(
        //滚动方向
        scrollDirection: Axis.vertical,
        //页面滚动时触发
        onPageChanged: (int index){
        },
        children: [
          Container(
            color: Colors.red,
            child: Center(
              child: Text('第一页',style: TextStyle(color: Colors.white),),
            ),
          ),
          Container(

            child: Center(
              child: Text('第二页',style: TextStyle(color: Colors.white),),
