How to Play a Custom Sound In Flutter ??

From the plugin’s README:

Future play() async {
  final result = await;
  if (result == 1) setState(() => playerState = PlayerState.playing);

// add a isLocal parameter to play a local file
Future playLocal() async {
  final result = await;
  if (result == 1) setState(() => playerState = PlayerState.playing);

Future pause() async {
  final result = await audioPlayer.pause();
  if (result == 1) setState(() => playerState = PlayerState.paused);

Future stop() async {
  final result = await audioPlayer.stop();
  if (result == 1) {
    setState(() {
      playerState = PlayerState.stopped;
      position = new Duration();

A simple solution for playing a file already defined in assets is using AudioCache. Library: More about AudioCache After adding the library to pubspec.yaml, import required class:

add an asset in the same file and place the file with sound to the assets folder (if you don’t have this folder, create it)

- assets/sound_alarm.mp3

then add this code:

static AudioCache player = new AudioCache();
const alarmAudioPath = "sound_alarm.mp3";;

An example here

The audio players’ works

  • Add the library to your pubspec.yaml:
    audioplayers: ^0.15.1
  • In pubspec.yaml under flutter add the reference to your assets file:
           - assets/yes.mp3

    MAKE SURE it is under the assets folder. It does not work when it is in a subfolder. For example, something like – assets/sounds/yes.mp3 will not work. Just put your audio file in the assets folder, not in its subfolder.

  • import the library in your app as an import package:audioplayers/audioplayers.dart;
  • then define this function:
    Future<AudioPlayer> playLocalAsset() async {
        AudioCache cache = new AudioCache();
       //At the next line, DO NOT pass the entire reference such as assets/yes.mp3. This will not work.
       //Just pass the file name only.
        return await"yes.mp3"); 
  • call the function whenever you need to play a sound: await playLocalAsset();
