firebase - Why does not create the short link?

Question

I've trying to make programmatically a dynamic link with parameters, but does not create the short link. Here is the code:

Future<Uri> createDynamicLink({@required String userName}) async {
    final DynamicLinkParameters parameters = DynamicLinkParameters(
      uriPrefix: 'https://proyectoihc2.page.link',
      link: Uri.parse('https://proyectoihc2.page.link/' + userName),
      androidParameters: AndroidParameters(
        packageName: 'com.example.proyectoihc2',
        minimumVersion: 0,
      ),
      dynamicLinkParametersOptions: DynamicLinkParametersOptions(
        shortDynamicLinkPathLength: ShortDynamicLinkPathLength.short,
      ),
      iosParameters: IosParameters(
        bundleId: 'com.google.FirebaseCppDynamicLinksTestApp.dev',
        minimumVersion: '0',
      ),
    );

    Uri url;

    final ShortDynamicLink shortLink = await parameters.buildShortLink();
    url = shortLink.shortUrl;

    print(url.toString());
  }

Does not print anything at all. What I'm doing wrong?
