我正在 Android Studio 中开发一个 Flutter 应用程序。当我在代码中的某个位置放置断点时，它会被击中并停止执行，但半秒后应用程序会退出并出现以下错误：
Unhandled exception:
FileSystemException: Cannot open file, path = 'build\app.dill.track.dill.incremental.dill' (OS Error: The requested operation cannot be performed on a file with a user-mapped section open.
, errno = 1224)

如果我运行应用程序而不进行调试，它可以正常工作。有没有人遇到类似错误并成功解决的？
断点似乎按预期工作。这里发生的情况看起来像是应用程序中的函数需要一个在断点之后未提供的值。通过检查是否有任何函数需要被断点阻止的值来调试应用程序。
将 flutter 升级到最新版本，然后升级你的软件包，然后进行 flutter clean 并重试
