初始化实现代码

Future<String?> initFBDeferredDeeplinks() async {
    String? deepLinkUrl;
    // Platform messages may fail, so we use a try/catch PlatformException.
    try {
      deepLinkUrl = await FlutterFacebookAppLinks.initFBLinks();
      if (Platform.isIOS) {
        deepLinkUrl = await FlutterFacebookAppLinks.getDeepLink();
      }

      if (deepLinkUrl != null && deepLinkUrl.isNotEmpty) {
        if (kDebugMode) {
          print("initFBDeferredDeeplinks $deepLinkUrl");
        }

        if (deepLinkUrl.contains("example://prod/")) {
          return deepLinkUrl.split("example://prod/").last;
        } 
        return deepLinkUrl;
      } else {
        return null;
      }
    } catch (e) {
      if (kDebugMode) {
        print(e);
      }
      return null;

      /// in case of error...
