我使用 in_app_purchase 3.0.6

  late StreamSubscription<dynamic> _subscription;
  List<ProductDetails> _products = [];
  InAppPurchase inAppPurchase = InAppPurchase.instance;
  @override
  void initState() {
    final Stream purchaseUpdated = inAppPurchase.purchaseStream;
    _subscription = purchaseUpdated.listen((purchaseDetailsList) {
      _listenToPurchaseUpdated(purchaseDetailsList);
    }, onDone: () {
      _subscription.cancel();
    }, onError: (error) {});
    super.initState();
    initStoreInfo();
    super.initState();
  }

  void _listenToPurchaseUpdated(List<PurchaseDetails> purchaseDetailsList) {
    purchaseDetailsList.forEach((PurchaseDetails purchaseDetails) async {
      if (purchaseDetails.status == PurchaseStatus.pending) {
      } else {
        if (purchaseDetails.status == PurchaseStatus.error) {
          ScaffoldMessenger.of(context).showSnackBar(
            SnackBar(
              behavior: SnackBarBehavior.floating,
              backgroundColor: Colors.red,
              content: const Text('Error purchasing subscription'),
              action: SnackBarAction(
                label: 'Close',
                textColor: Colors.white,
                onPressed: () {},
              ),
            ),
          );
        } else if (purchaseDetails.status == PurchaseStatus.purchased ||
            purchaseDetails.status == PurchaseStatus.restored) {
          setState(() {
            isPro = true;
          });
          final prefs = await SharedPreferences.getInstance();
          await prefs.setString(
            date,
            (DateTime.now().add(
              const Duration(days: 7),
            )).toIso8601String(),
          );
        }
        if (purchaseDetails.pendingCompletePurchase) {
           await InAppPurchase.instance.completePurchase(purchaseDetails);
        }
      }
    });
  }

  initStoreInfo() async {
    final bool available = await InAppPurchase.instance.isAvailable();
    if (!available) {}
    ProductDetailsResponse productDetailResponse = await inAppPurchase.queryProductDetails(
      _productIds,
    );
    if (productDetailResponse.error == null) {
      setState(() {
        _products = productDetailResponse.productDetails;
      });
    }
  }
