TextEditingController

for simplify form control , set TextEditingController is not supported on some fields , eg : FormeTextField,FormeNumberField,FormeDateTimeField and etc...

if you want to access underlying TextEditingController, you can try to convert FormeFieldController to FormeTextFieldController or other to do that
