Implementation

@override
void validate(String? path, Schema schema, dynamic value,
    List<ValidationResult> results) {
  if (_values.isEmpty) return;

  var name = path ?? 'value';
  var found = false;

  for (var i = 0; i < _values.length && !found; i++) {
    var thisValue = _values[i];

    if (ObjectComparator.compare(value, 'EQ', thisValue)) {
      found = true;
      break;
    }
  }

  if (!found) {
    results.add(ValidationResult(
        path,
        ValidationResultType.Error,
        'VALUE_NOT_INCLUDED',
        name + ' must be one of ' + _values.join(','),
        _values,
        null));
  }
