Using the Audioplayers Package to Fix Audio Cache Issues in Flutter

Working with audio is a typical requirement for developing Flutter apps, and the audioplayers package offers a strong tool for managing audio playback. However, using this package can result in audio cache-related issues. In this article, we’ll go over how to handle these problems.

Introduction

Flutter audio cache issues can be annoying, and they frequently happen when you’re using the audioplayers package. When trying to play audio files from multiple sources, such as assets or network resources, several problems may appear. The misinterpretation or abuse of the audio cache is one frequent cause of these issues.

Recognising the Issue

An audio cache that automatically stored audio files as part of the audioplayers package previously enhanced playing efficiency and decreased latency. However, the audio cache is no longer utilised by default in some of the more recent versions of the software. Because of this, developers who assume the cache will function normally may run into problems.

Solution

Consider the following remedy to fix audio cache issues:

Audiplayers package update: Make sure your Flutter project is utilising the most recent version of the audioplayers package. Change the following in your pubspec.yaml file:

dependencies:
audioplayers: ^latest_version

Substitute the most recent version number from pub.dev for latest_version.

Change Your Code: You can alter your code in the following way to prevent audio cache errors:

import 'package:audioplayers/audioplayers.dart';
child: ElevatedButton(
onPressed: () async {
final player = AudioPlayer();
await player.play(AssetSource('note1.wav'));
},
)

This code plays the audio file directly without using the audio cache by creating an instance of the AudioPlayer class. You can avoid possible audio cache-related issues by doing this.

Example

import 'package:flutter/material.dart';

import 'package:audioplayers/audioplayers.dart';

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

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        body: SafeArea(
          child: Center(
            child:TextButton(
        onPressed: () async {
      final player = AudioPlayer();
      await player.play(
          AssetSource('note1.wav'));
    }, child: Text('Click Me'),
    ),
    ),
        ),
      ),
    );
  }
}

Conclusion

It is possible to fix audio cache issues in Flutter, which are frequently experienced when using the audioplayers package, by realising that the audio cache is no longer used by default in more recent versions. Make sure your audioplayers package is up to date and change your code to play audio without using the cache to avoid these problems. This method will fix the problem and make it easier for your Flutter application’s audio playing.
