not getting song files in my app after using flutter audioQuery

December 6, 2021

I’ve tried every thing to get songfiles on my app but it still shows nothing, here is my code below:
”’

   import 'package:flutter/cupertino.dart';

   import 'package:flutter/material.dart';

   import 'package:flutter_audio_query/flutter_audio_query.dart';

    class slist extends StatefulWidget {

@override
_slistState createState() => _slistState();
}

    class _slistState extends State<slist> {
    final FlutterAudioQuery audioQuery = FlutterAudioQuery();
     List<SongInfo> songs = [];

      @override
    void initState() {
super.initState();
getAllSongs();

}

      Future<void> getAllSongs() async {
songs = await audioQuery.getSongs();

}

      @override
      Widget build(BuildContext context) {
        return Scaffold(
  backgroundColor: Colors.grey[900],
  body: ListView.builder(
    itemCount: songs.length,
    itemBuilder: (context, index) {
      return ListTile(
        leading: Image.asset(
          songs[index].albumArtwork != null
              ? songs[index].albumArtwork
              : "assets/placeholder.png",
        ),
        title: Text(songs[index].title),
        subtitle: Text(songs[index].artist),
      );
    },
  ),
);

}
}

>Solution :

Calling getAllSongs() inside the initState will (if possible) load the songs but not change the widget state, you have two options:

1- Add a setState after getAllSongs():

Future<void> getAllSongs() async {
  songs = await audioQuery.getSongs();
  setState(() {});
}

2- Load the items inside the widget tree:

@override
Widget build(BuildContext context) {
  return Scaffold(
    backgroundColor: Colors.grey[900],
    body: FutureBuilder(
      future: getAllSongs(),
      builder: (context, item) {
        // Null data
        if (item.data == null) return const CircularProgressIndicator();

        // Empty list
        if (item.data!.isEmpty) return const Text("Nothing found!");

        // Load items
        songs = item.data!;
        return ListView.builder(
          itemCount: songs.length,
          itemBuilder: (context, index) {
            return ListTile(
              leading: Image.asset(
                songs[index].albumArtwork != null
                    ? songs[index].albumArtwork
                    : "assets/placeholder.png",
              ),
              title: Text(songs[index].title),
              subtitle: Text(songs[index].artist),
            );
          },
        );
      },
    ),
  );
}
