ios 开始录制返回的数据显示失败

[tzt1994]

日志如下：
flutter: 路径(true: /var/mobile/Containers/Data/Application/5D056127-89C3-49DF-B9DF-EF87403D989A/Documents/screenRecord screenRecord20230219150228 startRecording: w x h = 1290 x 2796 pixels Error Error Domain=NSCocoaErrorDomain Code=4 "“screenRecord20230219150228.mp4” couldn’t be removed."

开启录制返回的success字段是false，这个日志是在录制前，会把文件先删除抛出的错误
这段代码，有什么用意
