i am trying to make a music app using audio query and just_audio packages and i am able to send a song detail to next page which i am currently playing but i can't find a way to send whole list to next page. at the moment i am able to play songs and pause them but not able to go to next and previous songs.

Inside your FutureBuilder<List>:

future: audioQuery.querySongs(),
builder: (context, snapshot) {
if (snapshot.data == null) {
    return const Center(child: CircularProgressIndicator());
}
if (snapshot.data!.isEmpty) {
    return const Center(child: Text('No data found'));
}
List<SongModel> songs = item.data!;

return ListView.builder(
    itemCount: snapshot.data!.length,
    itemBuilder: (context, index) {

    return ListTile(
        onTap: () async {
        await _setAudioSource(player: audioPlayer, songs: songs, initialIndex: index);
        audioPlayer.play();
        Navigator.push(
            context,
            MaterialPageRoute(
            builder: (context) => PlayerView(
                // You dont need this parameter anymore and if you wanted
                // you could just send the song list as argument as well
                //songModel: snapshot.data![index],
                audioPlayer: audioPlayer,
            ),
            ),
    );

Then create a helper method to set the source:

void _setAudioSource({
  required AudioPlayer player
  required List<SongModel> songs, 
  int initialIndex = 0,
}) async => await player.setAudioSource(
  ConcatenatingAudioSource(
    // Start loading next item just before reaching it.
    useLazyPreparation: true, // default
    // Customise the shuffle algorithm.
    shuffleOrder: DefaultShuffleOrder(), // default
    // Specify the items in the playlist.
    // Not sure if [SongModel.uri] will be always populated
    // you can change the logic to use data (the song itself) instead
    children: songs.map((songModel) => AudioSource.uri(songModel.uri!)).toList(),
  ),
  // Playback will be prepared to start from track1.mp3
  initialIndex: initialIndex, // default
  // Playback will be prepared to start from position zero.
  initialPosition: Duration.zero, // default
);

I ran into a new issue nvm i am new in flutter so now i am able to loop through the list but when on player view which is a different file and widget i can skip only one song and then it keeps skipping to the current song which is probably due to not updating the current information of song and i can't find a way to do that. Looking for a solution. and Thank you!
