form_class is not in kwargs if the method is declared like this
def formfield(self, form_class=forms.CharField, **kwargs):
a possible solution is to use a code like this
def formfield(self, **kwargs):
form_class = kwargs.pop("form_class", self.choices and
forms.TypedChoiceField or forms.CharField)
in that way is no form_class is passed, a default form_class is
defined (TypedChoiceField or CharField)
