Get only changed fields in useForm

[valbertVieira]

Has some built-in utility to get only changed fields using useForm?

actually workaround

const {  handleSubmit, isFieldDirty, values } = useForm()

const onSubmit = handleSubmit( (formBody) => {
  const modifiedFields: { [key: string]: any } = {}

    for (const key in values) {
      if (isFieldDirty(key as any)) {
        modifiedFields[key] = values[key as keyof typeof values]
      }
   }
 }
