感谢您检查扑！

今天Flutter SDK（截至2017年5月5日）没有内置支持播放和控制任意音频。不过，我们设计了我们的插件系统来支持它。

该插件添加到扑音频支持：https://pub.dartlang.org/packages/audioplayer

从插件的自述：

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(); 
    }); 
    } 
}
