we probably can skip this hack too: #635

<RHF control={control} name="test" />

<Controller control={control} name="test" />

(we will export all types as well)

import { useForm } from 'react-hook-form';

🚨import useForm from 'react-hook-form'; will no longer work

type form = {
  yourDetail: {
    firstName: string,
  }
}

errors?.yourDetail?.firstName

triggerValidation('firstName');
triggerValidation(['firstName', 'lastName']);

watch(); // { 'test.firstName': 'bill' }
watch({ nest: true }); // { test: { firstName: 'bill' } }

register('test', { required: true });

setError('yourDetail.firstName', 'test');
errors.yourDetails.firstName;
