Scaffold.of() 在显示小吃店颤动时使用不包含脚手架错误的上下文调用
Scaffold.of() called with a context that does not contain a Scaffold error when showing snack bar flutter
在我的屏幕上，我有一个 ScrollablePositionedList.builder，我正在使用 slidable 来滑动删除数据库中的记录，我弹出一个显示确认对话框，在用户确认删除后我想要显示一个用于撤消的小吃店。在添加确认对话框小吃店之前显示正常，但现在我得到 Scaffold.of() called with a context that does not contain a Scaffold.. 我需要在显示它之前调用 Navigator.pop(context) 以关闭确认对话框所以认为这是我尝试评论的原因它出来了，但我仍然得到错误。
你能发现我在这里做错了什么吗？我还想在 BlocLister 中收到 BookingDeleted 状态时显示小吃店，因为它在 Scaffold 树之前如何实现它？
一如既往，非常感谢您的帮助。
