the compiler tells me that error is here
late final TextEditingController _email;
late final TextEditingController _password;
that is the debug-console
The following LateError was thrown while finalizing the widget tree:
LateInitializationError: Field '_email@598051279' has already been initialized.
When the exception was thrown, this was the stack
#0 LateError._throwFieldAlreadyInitialized (dart:_internal-patch/internal_patch.dart:201:5)
#1 _LoginViewState._email=
