effectiveErrorText property

@override String get effectiveErrorText

errorText first, then the legacy invalidFeedbackText while the field is invalid, then the message of the automatic validation.

Implementation

@override
String get effectiveErrorText {
  final externalMessage = errorText.trim();
  if (externalMessage.isNotEmpty) {
    return externalMessage;
  }

  final legacyMessage = invalidFeedbackText.trim();
  if (legacyMessage.isNotEmpty && effectiveInvalid) {
    return legacyMessage;
  }

  return validationIssue?.message ?? '';
}
