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
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();
});
}
}
