Flutter 调试器在运行应用程序几秒钟后变得无响应

Question

我正在我的 M2 Macbook 上的 VS Code 中运行和调试一个 flutter 应用程序。但现在出现了一个问题，比如我在启动几秒钟后无法重新加载或重新启动应用程序。开发工具也没有出现。在 Windows 中也面临类似的问题，所以我认为这不是与平台相关的问题。

有人遇到过类似的问题吗？

这就是我得到的详细内容

Answer 1

刚刚解决了这个问题。

我看到我使用的 isar 包由于对其缓存进行 2 次背对背写入而形成死锁，因此持有异步写入线程。

总而言之，真正的罪魁祸首是一个在后台运行的线程，这使得整个调试器没有响应。
