android api 34, sendCancelIfRunning: isInProgress=falsecallback=io.flutter.embedding.android.FlutterActivity

Android API 34
**Describe the bug**
When I use flutter_downloader to download files in flutter, the following information is displayed in the android emulator
```
W/WindowOnBackDispatcher( 5234): sendCancelIfRunning: isInProgress=falsecallback=io.flutter.embedding.android.FlutterActivity$1@98a3d9
```
flutter code:
```dart
FlutterDownloader.cancelAll();

final taskId = await FlutterDownloader.enqueue(
url: url,
savedDir: savedDir,
fileName: fileName,
showNotification: true,
saveInPublicStorage: true,
openFileFromNotification: false,
);

FlutterDownloader.registerCallback(_downloadCallback);
```

AndroidManifest.xml:
```xml

```
**There is no other information and the callback function is not called**
I have no idea where I'm going wrong, can anyone provide some help?
