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 fileFuture 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(); }); }}
