嗨，我正在开发一个flutter应用程序。在这个应用程序中，一些声音从我的网站下载并保存到本地文件存储中。播放一些图片时播放。
这在安卓手机中正常工作。但我不能在IOS模拟器中做到这一点。我已经控制了文件是否正确下载。我看过模拟器文件，也看过声音文件，所以下载得很好。我的播放声音代码是这样的。
Future play(File soundFile) async {
debugPrint("sound: play enter");
try {
await advancedPlayer.stop();
advancedPlayer.setReleaseMode(ReleaseMode.RELEASE);
if (soundFile != null) {
print(soundFile.uri);
advancedPlayer.play(soundFile.uri.toString(), isLocal: true);
await advancedPlayer.onPlayerCompletion.first;
debugPrint("sound: played");
// advancedPlayer.stop();
}
} catch (e) {
debugPrint("sound: error");
}
debugPrint("sound: play leave");
}
在这段代码中，程序在这一行等待，而不是不转到下一行。await advancedPlayer.onPlayerCompletion.first;我没有看到任何错误。
我已经打印了声音文件的路径并控制了它，它在文件存储中。音频文件的格式为mp3。
在我的pubspec.yaml文件中，我尝试了0.17.4和0.16.2版本。我不能使用0.18.x版本(因为其他软件包不允许我使用(
audioplayers: ^0.17.4
非常感谢
