错误代码展示

  jumpToPage(String itemNameList) {
   switch(itemNameList){
     case "AnimatedContainer":
       Navigator.push(context,    MaterialPageRoute(
           builder: (context) => new AnimatedContainerPage()));
       break;
   }

修改为

jumpToPage(BuildContext context,String itemNameList) {
   switch(itemNameList){
     case "AnimatedContainer":
       Future.delayed(Duration.zero, () {
         Navigator.push(context,    MaterialPageRoute(
             builder: (context) => new AnimatedContainerPage()));
       });
       break;
   }
