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<AudioPlayerWidget> { static const double _controlSize = 56; static const double _deleteBtnSize = 24;

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

}

@override void dispose() { _playerStateChangedSubscription.cancel(); _positionChangedSubscription.cancel(); _durationChangedSubscription.cancel(); _audioPlayer.dispose(); super.dispose(); }

@override Widget build(BuildContext context) { return LayoutBuilder( builder: (context, constraints) { return Column( mainAxisSize: MainAxisSize.min, children: [ Row( mainAxisSize: MainAxisSize.max, mainAxisAlignment: MainAxisAlignment.spaceBetween, children: <Widget>[ _buildControl(), _buildSlider(constraints.maxWidth), if (widget.showDeleteIcon) ...[ IconButton( icon: const Icon(Icons.delete, color: ThemeColors.indicatorRed, size: _deleteBtnSize), onPressed: () { if (_audioPlayer.state == ap.PlayerState.playing) { stop().then((value) => widget.onDelete()); } else { widget.onDelete(); } }, ), ], ], ), if (_duration != null) ...[ LabelWidget( alignment: Alignment.center, title: '${prettyDuration(_duration!)}'), ], ], ); }, ); }

String prettyDuration(Duration duration) { var seconds = (duration.inMilliseconds % (60 * 1000)) / 1000; if (duration.inMinutes != 0) { return '${duration.inMinutes}m ${seconds.truncate()}s'; } else { return '${seconds.truncate()}s'; } }

Widget _buildControl() { Icon icon; Color color;

if (_audioPlayer.state == ap.PlayerState.playing) {
  icon = const Icon(Icons.pause, color: ThemeColors.myDarkColor, size: 30);
  color = ThemeColors.myDarkColorTerciary;
} else {
  final theme = Theme.of(context);
  icon = const Icon(Icons.play_arrow,
      color: ThemeColors.myDarkColor, size: 30);
  color = ThemeColors.myDarkColorTerciary;

    color: color,
    child: InkWell(
      child:
          SizedBox(width: _controlSize, height: _controlSize, child: icon),
      onTap: () {
        if (_audioPlayer.state == ap.PlayerState.playing) {
          pause();
        } else {
          play();
        }
      },
    ),
  ),
);

}

Widget _buildSlider(double widgetWidth) { bool canSetValue = false; final duration = _duration; final position = _position;

if (duration != null && position != null) {
  canSetValue = position.inMilliseconds > 0;
  canSetValue &= position.inMilliseconds < duration.inMilliseconds;
}

double width = widgetWidth - _controlSize - _deleteBtnSize;
if (widget.showDeleteIcon) {
  width -= _deleteBtnSize;
} else {
  width += _deleteBtnSize;
}

return SizedBox(
  width: width,

        final position = v * duration.inMilliseconds;

    },
    value: canSetValue && duration != null && position != null
        ? position.inMilliseconds / duration.inMilliseconds
        : 0.0,

Up, i have the same issue

[rubamapps]

@rxlabz is there any fix schedule of this?

[cristian1980]

Can someone add this f15b414135039b72760a908b95c01aa8c9da6422 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.

Same issue, but it occurs sometimes, not always. Can anyone provide an audio URL where it always occurs?

I have the same problem on Windows. Is there any way to solve this problem?
