flutter - 每次用户使用来自 firebase 的动态链接的应用程序安装我的应用程序时，我如何检测和奖励？

问题描述

我尝试在我的应用程序中添加动态链接。首先，我将 firebase 动态链接包添加到我的应用程序中，并进行了所有 firebase 配置。

我的最终目标是给分享链接的用户一个礼物，每次安装都用他的分享链接完成

这是我当前的实现，它为点击链接的用户赠送礼物，但不（我认为）为共享链接的用户赠送礼物。

class parrainage extends StatefulWidget {
  @override
  _parrainageState createState() => _parrainageState();
}

class _parrainageState extends State<parrainage> {
  int referral_gift=0;

  String _linkMessage;
  bool _isCreatingLink = false;
  String _testString =
      "Fais un appuis long sur le lien pour le copier";
  @override
  void initState() {
    super.initState();
    initDynamicLinks();

  }

  void initDynamicLinks() async {
    SharedPreferences prefs = await SharedPreferences.getInstance();

    referral_gift = prefs.getInt('referral_gift')??0;

    FirebaseDynamicLinks.instance.onLink(
        onSuccess: (PendingDynamicLinkData dynamicLink) async {
          final Uri deepLink = dynamicLink?.link;

          if (deepLink != null) {
            Navigator.pushNamed(context, deepLink.path);
            referral_gift=referral_gift+1;
            prefs.setInt('referral_gift', referral_gift); 

          }
        }, onError: (OnLinkErrorException e) async {
      print('onLinkError');
      print(e.message);
    });

    final PendingDynamicLinkData data =
    await FirebaseDynamicLinks.instance.getInitialLink();
    final Uri deepLink = data?.link;

    if (deepLink != null) {
      Navigator.pushNamed(context, deepLink.path);
      referral_gift=referral_gift+1;
      prefs.setInt('referral_gift', referral_gift); 
    }
  }

  Future<void> _createDynamicLink(bool short) async {
    setState(() {
      _isCreatingLink = true;
    });

    final DynamicLinkParameters parameters = DynamicLinkParameters(
      uriPrefix: 'https://XXXXX.page.link/XXXX',
      link: Uri.parse('https://XXXXXXXX.page.link/'),
      androidParameters: AndroidParameters(
        packageName: 'XXXXXXXXXXXXX',

        title: 'XXXXXXX',
        description: 'Débloque une fonction premium',
      ),
    );

    Uri url;
    if (short) {
      final ShortDynamicLink shortLink = await parameters.buildShortLink();
      url = shortLink.shortUrl;
    } else {
      url = await parameters.buildUrl();
    }

    setState(() {
      _linkMessage = url.toString();
      _isCreatingLink = false;
    });
