实现

factory PresentationRequest(url_OR_urls) {
  if ((url_OR_urls is String)) {
    return PresentationRequest._create_1(url_OR_urls);
  }
  if ((url_OR_urls is List<String>)) {
    List urls_1 = convertDartToNative_StringArray(url_OR_urls);
    return PresentationRequest._create_2(urls_1);
  }
  throw new ArgumentError("Incorrect number or type of arguments");
}
