只支持一个单玩家实例, 无效, 无效
原标题："just_audio_background supports only a single player instance, null, null"
I keep getting this error when I create an instance of AudioPlayer but I don t get it when I remove of instances of it from it from the code and when the check the plugins code I saw this method:
_JustAudioPlayer? _player;
@override
Future
init(InitRequest request) async {
if (_player != null) {
throw PlatformException(
code: "error",
message:
"just_audio_background supports only a single player instance");
}
_player = _JustAudioPlayer(
initRequest: request,
);
return _player!;
}
And that makes ZERO sense to me because what I m seeing here is if an instance of AudioPlayer exists then throw said error, but I need the instance to play audio(unless I m reading it wrong). Whenever there s an instance of AudioPlayer, in the widget I m using I get the error and then I can t play anything but without just_audio_background, everything works fine. The error just halts any use of AudioPlayer through out the app; it throws the same error anytime I load a widget that uses AudioPlayer. I tried using audioservice but I m having issues loading the song from network.
All the soltuions I ve seen concerning this error message had a different and was fixed but not in this case.

In the docs there is line:
...
It supports the simple use case where an app has a single AudioPlayer instance.
...
So, this is expected behaviour.
If you need a few instance of the audio player you could implements just_audio + audio_service(and maybe even audio_session).
