This issue is because you are creating new TextEditingController
every time your widget is rebuilt.
So to fix this issue, move these variables nameTextFieldController
,emailTextFieldController
outside your build method.
Like this:
TextEditingController nameTextFieldController = TextEditingController();
TextEditingController emailTextFieldController = TextEditingController();
@override
Widget build(BuildContext context) {
