Simple Audio

A cross-platform solution for playing audio in Flutter.

This project's goal is to be as simple as possible, meaning it offers the core functionality only (ex. play/pause). It also aims to be stable and relatively bug free.

I created this plugin for my music app so that I don't have to use different packages for different platforms (audio_service, dart_vlc). This made it hard to deal with bugs from different packages.

Features

• Simple API
• Cross platform (Android, Linux, Windows, iOS, macOS)
• Playback of local and online resources
• Gapless playback and preloading
• Volume normalization

Documentation

The documentation is hosted by pub.dev. You can find it here.

Usage

• Add this plugin as a dependency in pubspec.yaml
• Follow the setup steps.
• Call SimpleAudio.init() in main() (see below).
• Instantiate a SimpleAudio object in your player controller (see below).
• Use the APIs provided in the instantiated object (see below).

An example player project is located here.

Initialization

void main() async {
  WidgetsFlutterBinding.ensureInitialized();

  await SimpleAudio.init();

  runApp(const MyApp());
}

Create Player

final SimpleAudio player = SimpleAudio(shouldNormalizeVolume: false);

Open and Play

player.playbackState.listen((state) => print(state));
player.progressState.listen((state) => print(state));
// Autoplays by default
player.open(path);

Setup

Some platform specific things have to be set up in order for this plugin to function properly.

Windows, Linux, macOS, Android

No setup is needed.

iOS

You will have to add a dependency to your Xcode project.

• Open Runner.xcworkspace in the ios folder.
• At the top of your project hierarchy view, select the Runner project.
• Select the Runner target, go to the General tab and scroll down until you see Frameworks, Libraries, Embedded Content
• Press the + icon and add the AudioToolbox.framework framework. Select Do Not Embed under the Embed column.

Special Thanks

• sanihaq - Reported multiple bugs in simple_audio's first releases.
  These bugs would not have been fixed for a long time without their help.
