Flutter 如何去除用户订阅后的openapp广告？

Question

我正在尝试在我的 Flutter 应用程序上进行订阅付款，以便用户可以从中进行选择。

首先我在 Google Play 添加了三个订阅项目。 然后我制作了购买产品的代码。

这是我的代码

class IAPService {
  void listenToPurchaseUpdated(List<PurchaseDetails> purchaseDetailsList) {
    // ignore: avoid_function_literals_in_foreach_calls
    purchaseDetailsList.forEach((PurchaseDetails purchaseDetails) async {
      if (kDebugMode) {
        print("purchaseDetails.status ${purchaseDetails.status}");
      }
      if (purchaseDetails.status == PurchaseStatus.purchased ||
          purchaseDetails.status == PurchaseStatus.restored) {
        _handleSuccessfulPurchase(purchaseDetails);
      }

      if (purchaseDetails.status == PurchaseStatus.error) {
        if (kDebugMode) {
          print(purchaseDetails.error!);
        }
      }

      if (purchaseDetails.pendingCompletePurchase) {
        await InAppPurchase.instance.completePurchase(purchaseDetails);
        if (kDebugMode) {
          print("Purchase marked complete");
        }
      }
    });
  }

在我的 widger 屏幕上，付款不在 main.dart 上

  @override
  void initState() {
    super.initState();
    getuser();
    futureData = accountController.fetchAccounts();
    final Stream purchaseUpdated = InAppPurchase.instance.purchaseStream;
    iapSubscription = purchaseUpdated.listen((purchaseDetailsList) {
      if (kDebugMode) {
        print("Purchase stream started");
      }
      IAPService().listenToPurchaseUpdated(purchaseDetailsList);
    }, onDone: () {
      iapSubscription.cancel();
    }, onError: (error) {
      iapSubscription.cancel();
    }) as StreamSubscription<List<PurchaseDetails>>;

    initStoreInfo();
  }

但是我的主屏幕上打开的应用程序广告在我返回屏幕后弹出。dart 页面上弹出

class HomeScreenState extends State<HomeScreen>
    with SingleTickerProviderStateMixin, WidgetsBindingObserver {

  AppOpenManager appOpenManager = AppOpenManager();
  bool isPaused = false;

  @override
  void initState() {
    super.initState();
    WidgetsBinding.instance.addObserver(this);
  }

  @override
  void didChangeAppLifecycleState(AppLifecycleState state) {
    super.didChangeAppLifecycleState(state);
    if (state == AppLifecycleState.resumed) {
      isPaused = false;
      appOpenManager.showAdIfAvailable();
    } else if (state == AppLifecycleState.paused) {
      isPaused = true;
    }
  }

那么如何强制停止该广告我正在使用 Getx 作为状态管理，任何人都可以帮助我

Answer 1

我做到了， 我在加载广告之前添加了检查值

  @override
  void didChangeAppLifecycleState(AppLifecycleState state) {
    super.didChangeAppLifecycleState(state);
    if (userController.getuser!.ads) {
      if (state == AppLifecycleState.resumed) {
        isPaused = false;
        appOpenManager.showAdIfAvailable();
      } else if (state == AppLifecycleState.paused) {
        isPaused = true;
      }
    }
  }
