IAP 使用flutter_inapp_purchase 刷新商品列表报错？-灵析社区

IAP初始化商品报错``` FlutterInappPurchase.instance.getProducts(_productLists); ``` [BackgroundTask] Background Task 13 ("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. 1、重启试过了，没用 2、换其他手机没复现，功能正常 3、出问题的手机，每次调用API都这样 4、猜想是后台任务没结束，过了几个小时吧，还这样 5、iPhone网络设置还原过，没用 请大佬们指点思路，没太想明白。。。
