When using flutter_background_service, I am attempting to create a foreground service to allow my app access to the microphone when the user is off of the app. However, I get the foregroundServiceType 0x00000012 is not a subset of foregroundServiceType attribute 0x00000080 in service element of manifest file error whenever I run my app. Now, when reading the error I assumed what it is saying is I didn't add the necessary background service types to my AndroidManifest.xml file. But... I literally did. I checked documentation and it appears right. Here is my code and errors:
AndroidManifest.xml:

File where I use the foreground service code:
@override
void initState() {
super.initState();
_stopwatch = Stopwatch();
_audioRecorder = RecordPlatform.instance;
_initRecorder();
}
Whenever I attempt to start it, I call: stopForegroundService();
main.dart:
void main() async {
WidgetsFlutterBinding.ensureInitialized();
await Permission.notification.isDenied.then(
(value) {
if (value) {
Permission.notification.request();
}
},
);
await initializeService();
runApp(App());
}
