感谢您检查Flutter！

今天（截至2017年5月5日）的Flutter SDK不具有播放和控制任意音频的 内置 支持。但是，我们设计了插件系统来支持它。

该插件为Flutter添加了音频支持：https：//pub.dartlang.org/packages/audioplayer

从插件的自述文件中：

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();
    });
  }
}
