Flutter audio_service stream update notification with IcyMetadata - flutter

Question

I want to to a streamApp for just one stream/url.
In the audio_service example there is an MediaItem added in the AudioPlayerHandler.
This works so fahr but when IcyMedata updated the notification … obviously … has title and stuff from the added MediaItem. In the app i can update per _audioHandler.playbackstate and _player.icyMetadata!.info!.title! and some sting.splits(' - ') I can update Infos in the app with StreamBilder.
Also tried a dirty hack to add title in the PlaybackState object by changing the audio_service and add a title as property and connect it in the custom AudioHandler with _player.icy … .
But there must be a proper way to set metadata new or by this framework by itself. _audioHandler.updateMediaItem does nothing so far to the notification info, this is what i need!
I found a addStream … my try (Snippets)
Stream<MediaItem> _item() async* { MediaItem(
id: "http://stream.drumandbass.fm:9012",
title: "TEST",
artist: "Hello",
album: "Album",
duration: const Duration(milliseconds: 5739820),
genre: 'Drum and Bass',
artUri: Uri.parse('test.jpg'));
}
Future<AudioPlayerHandler> initAH() async {
return await AudioService.init(
builder: () => AudioPlayerHandler(),
config: const AudioServiceConfig(
androidNotificationChannelId: 'com.ryanheise.myapp.channel.audio',
androidNotificationChannelName: 'Audio playback',
androidNotificationOngoing: true,
),
);
class AudioPlayerHandler extends BaseAudioHandler {
/// Initialise our audio handler.
AudioPlayerHandler() {
// So that our clients (the Flutter UI and the system notification) know
// what state to display, here we set up our audio handler to broadcast all
// playback state changes as they happen via playbackState...
_player.playbackEventStream.map(_transformEvent).pipe(playbackState);
// ... and also the current media item via mediaItem.
mediaItem.addStream(_item());
// Load the player.
_player.setAudioSource(AudioSource.uri(Uri.parse(mediaItem.value!.id)));
}
// some play stop the rest of the example of audio_service
Widget:
FutureBuilder<AudioPlayerHandler>(
future: initAH(),
builder: (BuildContext context,
AsyncSnapshot<AudioPlayerHandler> snapshot) {
if (!snapshot.hasData) {
// while data is loading:
return Center(
child: CircularProgressIndicator(),
);
} else {
_audioHandler = snapshot.data!;
loaded = true;
// data loaded:
return Container();
}
},
),
… with _player.add(MediaItem()); like in example i get a snapshot.hasData but with addStream loaded keeps false.
I thankful for any tips to handle this issue properly.
thx,
Tom

if you are update you metadata you have just added updatemetadata of your view dart file otherwise set in initstate
like below
before you Add udioHandler.updateMediaItem() you need to update your Audiohandler file
