Wrong local assets playing on player completion

Open nicolo-fr opened this issue 3 years ago • 2 comments

Full Description I have several audiofiles in assets. I want the player to play the next track on completion. For that I've defined a recursive play function (see code below).
The first few tracks are being played OK. However, after 2 or 3 tracks have been played, the player the starts playing several of the previous tracks - for a fraction of a second - and I I get an error message . See the code below for a minimal example (you'll also find a link to a github repo which contains the audiofiles).

When I tapped play and let the player play a few tracks, I expected to see in the console : I/flutter (25557): track playing : 3 I/flutter (25557): track playing : 4 I/flutter (25557): track playing : 5 I/flutter (25557): track playing : 6 I/flutter (25557): track playing : 7

Instead I got the log reproduced below.

Code to Reproduce see here for github repo with asset files: https://github.com/nicolo-fr/audioplayers-bug-example

import 'package:audioplayers/audioplayers.dart';
import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatefulWidget {
  @override
  _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  static final AudioPlayer advancedPlayer = AudioPlayer();
  static final AudioCache audioCache = AudioCache(fixedPlayer: advancedPlayer);
  Stream<void> completionEvent = advancedPlayer.onPlayerCompletion;

  Future<void> play(int trackNbr) async {
    try {
      await audioCache.play('$trackNbr.flac');
      print('track playing : $trackNbr');
    } catch (e) {}

    if (trackNbr < 10) {
      completionEvent.listen(
        (event) {
          play(trackNbr + 1);
        },
      );
    }
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Material App',
      home: Scaffold(
        appBar: AppBar(
          title: Text('Example'),
        ),
        body: Center(
          child: ElevatedButton(
            child: Text('Play tracks'),
            onPressed: () {
              play(3);
            },
          ),
        ),
      ),
    );
  }
}
