Current bug behaviour

I try to set the external source as I was working and this error appears in simulator with iOS 18. Then I opened again simulator with 17.5 version and works perfectly, so there is some issue with the new iOS version.

`
import 'dart:async';

import 'package:audioplayers/audioplayers.dart' as ap;
import 'package:dependencies/dependencies.dart';

class AudioPlayerWidget extends StatefulWidget {
/// Path from where to play recorded audio
final String source;

/// Callback when audio file should be removed
/// Setting this to null hides the delete button
final VoidCallback onDelete;
final bool showDeleteIcon;
final bool getFromUrl;

const AudioPlayerWidget({
super.key,
required this.source,
required this.onDelete,
required this.showDeleteIcon,
required this.getFromUrl,
});

@OverRide
AudioPlayerState createState() => AudioPlayerState();
}

class AudioPlayerState extends State {

final _audioPlayer = ap.AudioPlayer()..setReleaseMode(ReleaseMode.stop);
late StreamSubscription _playerStateChangedSubscription;
late StreamSubscription<Duration?> _durationChangedSubscription;
late StreamSubscription _positionChangedSubscription;

Duration? _duration;

@OverRide
void initState() {
_playerStateChangedSubscription =
_audioPlayer.onPlayerComplete.listen((state) async {
await stop();
});
_positionChangedSubscription = _audioPlayer.onPositionChanged.listen(
(position) => setState(() {
_position = position;
}),
);
_durationChangedSubscription = _audioPlayer.onDurationChanged.listen(
(duration) => setState(() {
_duration = duration;
}),
);

_audioPlayer.setSource(_source);

super.initState();

}

Up, i have the same issue

[rubamapps]

@rxlabz is there any fix schedule of this?

[cristian1980]

Can someone add this f15b414 so we don't get 'Unknown error'

Experiencing the same, the first times it works, but after setting the URL source on consecutive sounds, like 9 times usually it fails.

I also noticed this happening, after a second audio library that reproduces other types of sounds in my app failed, it had an exception and followed by that exception I got this one on the audioplayers library. -> In case it provides more feedback, it could be that both libraries interact on the native part.
