firstError property

FormValidationError? get firstError

The first failed rule's response, or null when every rule passed.

Unlike errorResponses this does not build a list, so it is safe to call on every keystroke.

Implementation

FormValidationError? get firstError {
  for (final FormValidationResponse response in responses) {
    if (response is FormValidationError) return response;
  }
  return null;
}
