Question

我在我的应用程序中使用软件包 flutter 音频播放器来播放来自谷歌云 tts 的音频。它在 iOS 模拟器上运行良好，但是当我构建 apk 时出现以下错误：

预先感谢您的帮助。

Answer 1

据我所知，它是一个 bug。

与所有错误一样，您可以等待修复或降级软件包，直到找到仍然有效的版本。

或者，您可以自己挖掘 code，修复它并打开 pull request。

Answer 2

您可以尝试在 build.gradle 上将 ext.kotlin_version 升级到 '1.4.21' 它对我有用！ Github Discussion

Answer 3

正如@Teja 正确指出的那样，错误在于您的项目使用的是过时的 kotlin 版本，该版本不支持尾随逗号等某些功能。

真正的解决方法是更新您的应用配置（如上所述）。

然而，为了避免混淆，我合并了这个 PR，它也降级了我们的代码，以便它可以在旧版本的 kotlin 上运行。已在 0.17.3 及更高版本合并和发布（目前我们在 0.17.4）。

因此，这是固定的。没有理由再在您的应用上降级 AP。
