解决Mac升级OS版本至Catalina之后，flutter iPhone无法真机调试的问题

以下命令可以解决这个问题：

1. sudo xattr -r -d com.apple.quarantine 路径/flutter/bin/cache/artifacts/libimobiledevice/idevice_id
2. sudo xattr -r -d com.apple.quarantine 路径/flutter/bin/cache/artifacts/libimobiledevice/idevicename
3. sudo xattr -r -d com.apple.quarantine 路径/flutter/bin/cache/artifacts/libimobiledevice/idevicescreenshot
4. sudo xattr -r -d com.apple.quarantine 路径/flutter/bin/cache/artifacts/libimobiledevice/idevicesyslog
5. sudo xattr -r -d com.apple.quarantine 路径/flutter/bin/cache/artifacts/libimobiledevice/ideviceinfo
6. sudo xattr -r -d com.apple.quarantine 路径/flutter/bin/cache/artifacts/usbmuxd/iproxy

将路径替换为flutter sdk所在的路径。
