Flutter iOS RevenueCat 未捕获的异常 'NSInternalInconsistencyException'

Flutter iOS RevenueCat uncaught exception 'NSInternalInconsistencyException'

我在控制台中收到此错误:

[Purchases] - INFO: There is no singleton instance. Make sure you configure Purchases before trying to get the default instance.

但是,这是一个间歇性问题(即:并不总是发生)。事实上,我在启动时设置了 Purchases 实例(即:在用户通过身份验证并获得 UID 后立即):

 await Purchases.setDebugLogsEnabled(isDebugEnabled);
 await Purchases.setup(kRevenueCatApiKey, appUserId: uid);

有什么我遗漏的吗? (但大部分时间都有效)

我发现了问题。所以每当 getPurchaserInfo 被调用时,如果 Purchaser.setup 还没有完成处理,那么它就会触发这个异常。感谢上面@Cesar 的评论。

就我而言,我发现问题是因为:

  • 我有两个分别处理 IAP 和业务逻辑的 Bloc。
  • 一旦用户通过身份验证,IAP 就会调用 Purchases.setup。然后在主屏幕上,业务逻辑将通过 getPurchaserInfo.
  • 与服务器检查本地数据的有效性
  • 当互联网连接不是很好并且 getPurchaserInfoPurchases.setup 完成处理之前被业务逻辑块触发时,问题就出现了。

所以我所做的解决方案是确保业务逻辑块在 IAP 块完成 Purchases.setup 后开始初始化。例如将它们放在等待每个进程的异步函数中。
