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 _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:

But I can't find it in the files folder on my device?

Start at the FlutterDownloader.enqueue call and trace the iOS path through _prepareSaveDir and _getSavedDir, which currently uses the application Documents directory. Reproduce the download on iOS and inspect the task's saved path and completion behavior. Done means the downloaded file can be located or opened reliably on the device.
