Flutter热重启/热重载失效求助，关联Dart SDK目录监听异常

Flutter热重启/热重载功能完全无法正常工作，推测该问题与Dart SDK持续抛出的以下警告直接相关：

Socket error: FileSystemException: Directory watcher closed unexpectedly, path = 
'c:\Users\Saad\OneDrive\Documents\Scripts\mutanafisun'

以下是flutter doctor的输出信息：

解决方案 #

• 将项目从OneDrive同步目录迁移到本地非同步文件夹，比如把c:\Users\Saad\OneDrive\Documents\Scripts\mutanafisun移动到c:\Users\Saad\Projects\mutanafisun，避免云同步工具干扰文件系统监听
• 若不想移动项目，可关闭OneDrive对该项目文件夹的同步：右键任务栏OneDrive图标→设置→账户→选择文件夹→取消勾选目标项目文件夹
• 重启VS Code和终端，重新运行flutter run
• 尝试清除Flutter缓存并重新获取依赖：

  flutter clean
  flutter pub get
