Usage

1. Before you begin Add this permission to AndridManifest.xml:

<uses-permission android:name="android.permission.FOREGROUND_SERVICE"/>

Make sure your app uses Java8 by adding this code into your app-level build.gradle into the android section:

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

Enable androidx support in your app.

Add the service to AndroidMainfest.xml

<manifest>
  ...
  <application>
    ...
    ...
    <service 
      android:name="net.tailosive.flutter_audio_as_service.AudioService"/>
  </application>
</manifest>

2. Usage To start playback initialize the player with the following:

FlutterAudioAsService.init("Title", "Author", audioSource, appIcon, albumCover);

audioSource is a string - could be both a url or a file directory.

How to properly set appIcon and albumCover:

• put the desired .png image into android/src/main/res/drawable/
• if your resource is app_icon.png then set the appIcon value to be "app_icon"
• the value can be null

If you wish you can set event listeners as follows:

AudioPlayerListener listener = AudioPlayerListener(
  onPlayerStateChanged: (PlayerState playerState) {
    print(playerState);
  },
  onPlayerPositionChanged: (Duration playerPosition) {
    print(playerPosition.toString());
  },
  onPlayerCompleted: () {
    print("Player completed");
  }
);

FlutterAudioAsService.setListeners(listener);

Playback is controlled with the following functions:

FlutterAudioAsService.pause();
FlutterAudioAsService.resume();

During playback you may also seek with:

FlutterAudioAsService.seekBy(Duration(seconds: 30));
FlutterAudioAsService.seekTo(Duration(minutes: 15, seconds: 47));

To stop playback and destroy the service run:

FlutterAudioAsService.stop();

3. Features The plugin supports audio playback as an Android service with caching functionality included. It uses ExoPlayer with MediaSession API and rich notification controls.
