Fetching Saved Country,State,City from firestore and displaying to user

[fatfishdigital]

I am using version 0.2.6
I am trying to set the currentState and CurrentCity and CurrentCountry using setState((){
}); when fetching saved data from Firestore. now the problem is When i try to set the data i get this error " Unhandled Exception: setState() called after dispose(): CSCPickerState#a6452(lifecycle state: defunct, not mounted)
"
Is this expected behaviour or i am doing something wrong here
