查找停用的小部件的祖先是不安全的

Question

我获得了HTTPS中接口返回的错误代码，并通过Provider.of显示了该接口，但是在接口未返回时切换页面以提示此问题

I/flutter (10066): Looking up a deactivated widget's ancestor is unsafe.
I/flutter (10066): At this point the state of the widget's element tree is no longer stable.
I/flutter (10066): To safely refer to a widget's ancestor in its dispose() method, save a reference to the ancestor by calling dependOnInheritedWidgetOfExactType() in the widget's didChangeDependencies() method.

如何解决，谢谢
