这是我的 pubspec.yaml 文件中的包。
cloud_firestore: ^2.5.3
firebase_core_web: ^1.1.0
cloud_firestore_web: ^2.4.3
firebase_core: ^1.7.0
firebase_auth: ^3.1.2
provider: ^6.0.1
firebase_messaging: ^10.0.8
firebase_crashlytics: ^2.2.2
firebase_analytics: ^8.3.3
purchases_flutter: ^3.0.0
我在 Flutter 稳定通道版本 2.5.2 中运行所有内容。我也尝试使用颤振通道测试版 2.6.0-5.2.pre。
手机的iOS版本是15.0.1。我在 Iphone 7（物理设备，而不是模拟器）上运行测试。XCode 版本为 13.0。MAC OS 是 Big Sur 11.6（带 M1 芯片）。
该应用程序在 Android 上运行良好，但当我调用以下函数时，它会在应用程序启动时挂起：
Offerings rcOfferings;
rcOfferings = await Purchases.getOfferings();
而且该getOfferings()功能永远不会返回..它之前工作得非常好..
在更新过程中，我所做的唯一更改如下：删除以下内容： Purchases.identify(rcAppUserId);
改为使用： Purchases.logIn(rcAppUserId);
这是一个已知的问题？getOfferings() 函数从不返回任何东西的潜在原因是什么……？当这个函数被调用并且应用程序永远不会启动时它会挂起......</p>

[BackgroundTask] Background Task 12 ("SKProductsRequest"), was created over 30 seconds ago. In applications running in the background, this creates a risk of termination. Remember to call UIApplication.endBackgroundTask(_:) for your task in a timely manner to avoid this.

如上所示，它在一开始就列出了产品（我不太明白它是在哪个步骤中做到的）。
“CALLING RevenueCat getRcOfferings() function now...”这一行是调用 getOfferings() 函数的地方，应用程序在等待时挂起……当我说挂起时，它一直在等待这个异步调用完成。
希望这些额外的信息将有助于获得一些帮助......
