Validator on ListFieldBloc

Open andreag85 opened this issue 4 years ago • 1 comments

I have this bloc ListFieldBloc<InputFieldBloc<File, Object>> for selecting image files. Is it possible to add a validator for ListFieldBloc? I need to require that at least n images are inserted for a form, how can I do this?

Hi @andreag85, validator is not available, but for your case, you can use a BlocBuilder with the list field Bloc, and check the length of the fieldBlocs
