How to play a custom sound in Flutter?

Question

I was able to play a simple sound with this line of code:

SystemSound.play(SystemSoundType.click); 

How can I play a customized sound?

Let's say a short mp3

Answer 1

Simple solution for playing a file already defined in assets is using AudioCache. Library: https://pub.dartlang.org/packages/audioplayers. More about AudioCache After adding library to pubspec.yaml, import required class:

import 'package:audioplayers/audio_cache.dart'; 

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

assets: - assets/sound_alarm.mp3 

then add this code:

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

Thanks for checking out Flutter!

Flutter SDK today (as of May 5, 2017) doesn't have built-in support to play and control arbitrary audio. However, we designed our plugin system to support it.

This plugin adds audio support to Flutter: https://pub.dartlang.org/packages/audioplayer

From the plugin's README:

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