我想添加ofl，以便在桌面上打开链接时，链接将转到应用程序的Web版本
这是我的代码，我应该把它添加到哪里？

final DynamicLinkParameters parameters = DynamicLinkParameters(
      // The Dynamic Link URI domain. You can view created URIs on your Firebase console
      uriPrefix: uriPrefix,

      // The deep Link passed to your application which you can use to affect change
      link: Uri.parse(parsableLink),
      // Android application details needed for opening correct app on device/Play Store
      androidParameters: AndroidParameters(
          packageName: androidPackageName, fallbackUrl: Uri.parse(webLink)),

      // iOS application details needed for opening correct app on device/App Store
      iosParameters: IOSParameters(
          bundleId: iosPackageName, fallbackUrl: Uri.parse(webLink)),

      //longDynamicLink: Uri.parse('$parsableLink&ofl=$webLink')
    );

    final ShortDynamicLink shortDynamicLink =
        await dynamicLinks.buildShortLink(parameters);
    print(shortDynamicLink);

    return shortDynamicLink.shortUrl.toString();
