can't find file after ios download

The file seems to be downloading fine, but I cannot find the file on my device anywhere after it is downloaded.

I download it like this:

final taskId = await FlutterDownloader.enqueue( url: ref.read(resumeUrlSD), headers: {}, // optional: header send with url (auth token etc) // savedDir: externalDir!.path, savedDir: _localPath, showNotification: true, openFileFromNotification: true, saveInPublicStorage: _saveInPublicStorage,

                  );

In the console it shows:

externalStorageDirPath IOS: /var/mobile/Containers/Data/Application/014DCD70-5E34-41A3-95E0-868FEA48A189/Documents This is where I set up the download task:

late String _localPath; late bool _permissionReady; final bool _saveInPublicStorage = true; final ReceivePort _port = ReceivePort();

bool hasResume = false;

@override void initState() { super.initState(); _bindBackgroundIsolate(); FlutterDownloader.registerCallback(downloadCallback, step: 1); _prepare();

}

@pragma('vm:entry-point') static void downloadCallback( String id, DownloadTaskStatus status, int progress, ) {

print(
  'Callback on background isolate: '
      'task ($id) is in status ($status) and process ($progress)',
);

IsolateNameServer.lookupPortByName('downloader_send_port')
    ?.send([id, status, progress]);

if(status.toString() == "DownloadTaskStatus(3)" && progress == 100){
  print('2124:DOWNLOAD COMPLETE');
  FlutterDownloader.open(taskId: id);
}

}

@override void dispose() { _unbindBackgroundIsolate(); super.dispose(); }

void _bindBackgroundIsolate() { final isSuccess = IsolateNameServer.registerPortWithName( _port.sendPort, 'downloader_send_port', ); if (!isSuccess) { _unbindBackgroundIsolate(); _bindBackgroundIsolate(); return; } _port.listen((dynamic data) { final taskId = (data as List)[0] as String; final status = data[1] as DownloadTaskStatus; final progress = data[2] as int;

  print(
    'Callback on UI isolate: '
        'task ($taskId) is in status ($status) and process ($progress)',
  );
  print('2124: PROGRESS $progress');

  if(progress == 100){
    print('2124: PROGRESS 100');
    OpenFilex.open(_localPath);
    Fluttertoast.showToast(
        msg: 'Coming soon', toastLength: Toast.LENGTH_LONG, timeInSecForIosWeb: 3);
  }

  // if (_tasks != null && _tasks!.isNotEmpty) {
  //   final task = _tasks!.firstWhere((task) => task.taskId == taskId);
  //   setState(() {
  //     task
  //       ..status = status
  //       ..progress = progress;
  //   });
  // }
});

}

void _unbindBackgroundIsolate() { IsolateNameServer.removePortNameMapping('downloader_send_port'); }

Future _prepareSaveDir() async { _localPath = (await _getSavedDir())!; final savedDir = Directory(_localPath); if (!savedDir.existsSync()) { await savedDir.create(); } }

Future<String?> _getSavedDir() async { String? externalStorageDirPath;

if (Platform.isAndroid) {
  try {
    externalStorageDirPath = await AndroidPathProvider.downloadsPath;
    print('2124: externalStorageDirPath: $externalStorageDirPath');
  } catch (err, st) {
    print('failed to get downloads path: $err, $st');

    final directory = await getExternalStorageDirectory();
    externalStorageDirPath = directory?.path;
  }
} else if (Platform.isIOS) {
  externalStorageDirPath =
      (await getApplicationDocumentsDirectory()).absolute.path;
  print('2124: externalStorageDirPath IOS: $externalStorageDirPath');

}
return externalStorageDirPath;

}

Future _prepare() async {

_permissionReady = await _checkPermission();
if (_permissionReady) {
  await _prepareSaveDir();
}

}

Future _checkPermission() async { if (Platform.isIOS) { return true; }

if (Platform.isAndroid) {
  final status = await Permission.storage.status;
  if (status == PermissionStatus.granted) {
    return true;
  }

  final result = await Permission.storage.request();
  return result == PermissionStatus.granted;
}

throw StateError('unknown platform');

} It seems to download fine. Here is the log:

Thanks but that is not the problem. I know why that error occurs. Caused by when call enqueue function I pass fileName, then when it complete, direct path being changed, so can't open. :D
