when dialog open and after close dialog when focus on textFormField widget rebuild unnecessarily and user doesn't able to put text in this - flutter

Question

When I click on the update profile button I want to show a dialog if no changes are found, but when I close this and try to change the username or email again the entire widget rebuilds twice as soon as I focus on the TextFormField.

It works fine if I don't open a dialog, but when I do this problem shows up again.
