我在这个目录“/storage/emulated/0/Android/data/com.myApp.test/files/myDownload.pdf”中有一个PDF文件，所以我想把它复制或移动到一个新目录，比如“/storage/emulated/0/Android/data/com.myApp.test/files/newFolder/newName.pdf” 但我陷入了这个错误
Unhandled Exception: FileSystemException: Cannot copy file to '/storage/emulated/0/Android/data/com.myApp.test/files/newFolder/newName.pdf', path = '/storage/emulated/0/Android/data/com.myApp.test/files/myDownload.pdf' (OS Error: No such file or directory, errno = 2)
我使用的代码是
final _externalDirectory = await getExternalStorageDirectory(); var dir = Directory(_externalDirectory.path); String path = _externalDirectory.path + '/' + newPath; getfileX().copy(path);
