Flutter keyboard done button causes textfield content to vanish
1
I have 2 textfields in a form. When i click on done button on keyboard in the second text field , keyboard hides and both the text fields get empty. The same happes when i closes the keyboard manually, then also the content of the textfields get lost.
It looks like the screen gets refresh evertime this happens. why is it so?

TextEditingController nameTextFieldController = TextEditingController();
TextEditingController emailTextFieldController = TextEditingController();
@override
Widget build(BuildContext context) {
