Looking up a deactivated widget's ancestor is unsafe.Flutter integaration test - flutter

Question

type here
iam new to flutter and trying to learn test integration test package and i have come around this error.
The following assertion was thrown while finalizing the widget
tree:
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.
and to the little understanding that i have this is the class throwing that error

}
the problem is the script runs and performs its actions but the test fails.
any guidance would be appreciated.if there is anymore information needed for clarification i'll be happy to provide it.
