bool equality(dynamic value, dynamic itemValue)

Implementation

bool equality(value, itemValue) {
  try {
    if (comparingBy == null) {
      if (multiple) {
        return values!.contains(itemValue);
      }
      return value == itemValue;
    }

    if (multiple) {
      return values!.any(comparingBy!(itemValue));
    }

    return comparingBy!(value) == comparingBy!(itemValue);
  } catch (e) {
    return false;
  }
}
