Clear a TextField without a TextEditingController. #111

Describe the bug
Currently, I manage a form in the same way as: https://github.com/felangel/bloc/tree/master/examples/flutter_form_validation

I have a feature where I need to be able to clear the field, but I don't see how to do this without using a TextEditingController.

I would only like to manage the state of my form in one place (in my Bloc) and avoid using TextEditingController and with listeners.

Do you have any ideas?

Thanks :)
