======== Exception caught by widgets library =======================================================
The following assertion was thrown building InheritedNavigator:
'package:flutter/src/widgets/framework.dart': Failed assertion: line 5675 pos 12: 'child == _child': is not true.


Either the assertion indicates an error in the framework itself, or we should provide substantially more information in this error message to help you determine and fix the underlying cause.
In either case, please report this assertion by filing a bug on GitHub:
  https://github.com/flutter/flutter/issues/new?template=2_bug.yml

The relevant error-causing widget was:
