无法销毁 activity Android: Google Play 控制台错误

Question

我正在尝试将我的应用程序发布到 Google Playstore 上。我已经使用 Flutter 创建了应用程序。但在发布前报告中我收到错误：

Stacktrace:

我试图找到任何讨论这个的东西，我发现了一个 Whosebug 问题，这个问题收到很差并且被否决了；这是对 the post 的引用。我不确定为什么会这样，我不确定这是我可以修复的外部问题还是内部错误。

制作时从Playstore下载的app，打开后白屏，一直这样。我不确定我收到此错误是否是此错误的结果。

如有任何帮助，我们将不胜感激！

Answer 1

我已经设法解决了我遇到的两个问题。我通过将 file_picker 库更新到版本 2.10 修复了此错误的第一个问题。此问题已在版本 2.0.12 中修复。我还修复了应用程序启动时白屏的第二个问题，降级为：classpath 'com.android.tools.build:gradle:3.4.3'。这是对 post 的参考，对我有帮助。
