如何在Flutter中播放自定義聲音？

Question

我能玩簡單的聲音這行代碼：

SystemSound.play(SystemSoundType.click); 

如何播放定製的聲音？

比方說一短mp3

感謝您檢查撲！

今天Flutter SDK（截至2017年5月5日）沒有內置支持播放和控制任意音頻。不過，我們設計了我們的插件系統來支持它。

該插件添加到撲音頻支持：https://pub.dartlang.org/packages/audioplayer

從插件的自述：

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(); 
    }); 
    } 
}
