在首页的时候直接使用HiBanner(bannerList),把原有代码先注释掉，如图图片描述，运行后报======== Exception caught by widgets library =======================================================
The following assertion was thrown building NotificationListener:
ScrollController not attached to any scroll views.
‘package:flutter/src/widgets/scroll_controller.dart’:
Failed assertion: line 105 pos 12: ‘_positions.isNotEmpty’ 图片描述，当我点击底部导航再次切换回到首页就正常了，请问老师这个是什么原因呢？
