网路超时报错

在趋势页面，选择一个语言的时候，网络超时，应该toast提示，但是遇到了报错，并且页面无提示，经过调试报错信息：
2023-03-26 13:35:46.217 32509-32559/com.shuyu.gsygithub.gsygithubappflutter I/flutter: Looking up a deactivated widget's ancestor is unsafe.
At this point the state of the widget's element tree is no longer stable.
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.

调试时发现，调用errorHandleFunction时，HttpErrorListener._context的_lifiesycleState状态是_ElementLifecycle.defunct，并且绑定_widget=null,貌似Element被卸载了
无法贴图，_context的信息我截图了，需要的话可以提供
