validator method

@override EskResult validator(dynamic value)

Validates the given value and returns the result.

Don't call directly, call validate instead.

Implementation

@override
EskResult validator(dynamic value) {
  final superRes = super.validator(value);
  if (superRes.isNotValid) return superRes;

  for (final field in fields) {
    final mapValue = value[field.id];
    // If the field is nullable, we can skip validation if the value is null
    if (mapValue == null && field.isNullable) continue;

    print(
      "Validating field: ${field.id}, value: $mapValue, with field: $field",
    );

    final result = field.validate(mapValue);
    if (result.isValid) continue;

    String error = '';

    if (field is EskMap) {
      error += '${field.id}.${result.error}';
    } else {
      error += '${field.id} to be ${result.error}';
    }

    return EskResult(
      isValid: result.isValid,
      error: error,
      value: mapValue,
    );
  }

  return EskResult.valid(value);
}
