Implementation

@override
FutureOr<bool> passes(ValidationContext context) async {
  final args = context.parameters;
  final value = context.value;
  final allowedTypes = _types?.map((e) => e.trim().toLowerCase()).toList() ??
      args.map((e) => e.trim().toLowerCase()).toList();

  if (value == null || allowedTypes.isEmpty) return false;

  if (!await FileRule().passes(context)) return false;

  if (value is UploadedFile) {
    return _validateMime(value, allowedTypes);
  } else if (value is List<UploadedFile>) {
    for (final item in value) {
      if (!await _validateMime(item, allowedTypes)) return false;
    }
  }
  return true;
