resolveUploadIdFromUploadDescription function

UuidValue? resolveUploadIdFromUploadDescription(String uploadDescription) {
  final uploadIdString = resolveMetadataFromUploadDescription(
    uploadDescription,
    'upload-id',
  );
  if (uploadIdString == null) {
    return null;
  }
  const uploadIdPrefix = 'upload-';
  if (!uploadIdString.startsWith(uploadIdPrefix)) {
    return null;
  }
  try {
    return UuidValue.withValidation(
      uploadIdString.substring(uploadIdPrefix.length),
    );
  } on FormatException {
    return null;
  }
}
