购买失败 Flutter flutter_inapp_purchase

Question

我在 iOS 中有一个非续订订阅，但在测试期间失败了。我正在使用 Flutter 库 flutter_inapp_purchase。我正在从 iTunesConnect 成功 load/fetch 获取产品，但在尝试购买时出现错误。在我成功输入我的 Sandbox 用户凭据后发生此错误。

我已经使用 Swift 中内置的应用程序的先前版本测试了此沙箱用户和 IAP 设置，一切都按预期工作，因此我相当确定问题是此 Flutter 特有的。

Answer 1

已解决！

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

2) 这吐出一个更有用的错误。我发现问题出在我的 XCode runner 项目中的内部版本号上。

修复：文档大纲 - 亚军确保选择了常规选项卡目标 - 亚军用数值而不是 $(FLUTTER....)

替换内部版本号
