购买失败Flutter flutter_inapp_purchase

Question

我在iOS中有一个非续订订阅，但在测试过程中失败。我使用的是Flutter库flutter_inapp_purchase。我正在成功地从iTunesConnect加载/获取产品，但在尝试购买时出现错误。此错误发生在我成功输入沙盒用户凭据之后。

我已经使用Swift中内置的应用程序的早期版本测试了这个沙箱用户和IAP设置，一切都像预期的那样工作，所以我相当确定这个问题是这个颤动的特定问题。

Answer 1

解决了！

1)我决定使用Google Flutter团队创建的包。https://pub.dev/packages/in_app_purchase

2)这会产生一个更有用的错误。我发现问题出在我的XCode runner项目的内部版本号上。

修复方法:文档大纲-运行器确保选择了常规选项卡目标-运行器将内部版本号替换为数值而不是$(FLUTTER...)
