Plalist fails with local asset files but OK with URL files.

Which API doesn't behave as documented, and how does it misbehave? Latest version

Minimal reproduction project

When I use audio files from web, as a playlist with ConcatenatingAudioSource , it is fine. Everything works. But when I use with local assets instead of web, Progressbar lost its position.

NOTE: This issue never happens on Android but on Windows.

IMPORTANT NOTE !!! Playing audio is fine, the problem is Progressbar which is properly used from apckage : "audio_video_progress_bar ". When go next song, progressbar position crashes/frezes . (With signle song it is fine)

NOTE: I tried ; AudioSource.asset() AND AudioSource.file() ... none of them worked.

// This is OK
final _playList = ConcatenatingAudioSource(
children: [
AudioSource.uri(Uri.parse("http://localhost:5000/song1")),
AudioSource.uri(Uri.parse("http://localhost:5000/song2")),
AudioSource.uri(Uri.parse("http://localhost:5000/song3")),
AudioSource.uri(Uri.parse("http://localhost:5000/song4")),
]);

// This has NOT OK : progressbar lost position and got frozen when hit next song.
final _playList = ConcatenatingAudioSource(
children: [
AudioSource.uri(Uri.parse("asset:///assets/songs/song1.mp3")),
AudioSource.uri(Uri.parse("asset:///assets/songs/song2.mp3")),
AudioSource.uri(Uri.parse("asset:///assets/songs/song3.mp3")),
AudioSource.uri(Uri.parse("asset:///assets/songs/song4.mp3")),
]);

To Reproduce (i.e. user steps, not code) Only Playlist have issu. Single track is OK.

Error messages ERROR message :

[just_audio_windows]: Broadcast playback evcent error: Error accessing BufferingProgress. Using default value of 1.

Expected behavior Smooth pass to next song.

On Windows, files use \ instead of /. May that be the cause?

[mastermeric]

No Bruno.. it is vice versa, \ is used for escape characters etc. Moreover Asset accessiblities are OK. Files are playing fine. Only the issue when we switch to next song, it craches the progressbar (as a playlist of ConcatenatingAudioSource )

Android has no problem, all playlist running smoothly. But on Windows , I get error like this : [just_audio_windows]: Broadcast playback evcent error: Error accessing BufferingProgress. Using default value of 1.
