我想播放本地文件的播放列表。 在android上,没有问题,我可以在Mediaitem(id)中添加一个本地文件并且它可以正确播放。但在 iOS 上它不起作用。
我收到那个错误:
[VERBOSE-2:ui_dart_state.cc(186)] Unhandled Exception: PlatformException((-1002)
unsupported URL, null, null, null)
#0 StandardMethodCodec.decodeEnvelope (package:flutter/src/services/message_codecs.dart:581:7)
#1 MethodChannel._invokeMethod (package:flutter/src/services/platform_channel.dart:158:18)
<asynchronous suspension>
#2 AudioService.updateQueue (package:audio_service/audio_service.dart:911:5)
<asynchronous suspension>
我知道这个错误来自 AudioService.updatequeue,当我设置了 AudioSource 但我不知道如何解决它。
void startAudioService() async{
List<MediaItem> playlist = [];
playlist.add(MediaItem(mylocalFile, ...));
await AudioService.start(
androidStopForegroundOnPause: true,
backgroundTaskEntrypoint: _audioPlayerTaskEntrypoint,
androidNotificationChannelName: 'AudioPlayer',
androidNotificationColor: 0xFF2196f3,
androidNotificationIcon: 'mipmap/ic_launcher',
androidEnableQueue: true,
);
await AudioService.updateQueue(playlist);
await AudioService.skipToQueueItem(playlist[widget.startIndex].id);
}
我尝试像这样设置音频源,但仍然出现错误:
AudioSource.uri(Uri.file(item.id));
error : [VERBOSE-2:ui_dart_state.cc(186)] Unhandled Exception: PlatformException(NoSuchMethodError: The getter 'sequence' was called on null.
onUpadeQueue :
@override
Future<void> onUpdateQueue(List<MediaItem> queue) async{
AudioServiceBackground.setQueue(_queue = queue);
await _player.setAudioSource(ConcatenatingAudioSource(
children: queue.map((item) => AudioSource.uri(Uri.parse(item.id))).toList(),
));
}
答案 0 :(得分:0)
我正在使用我的游戏,我更喜欢这种方式,
import 'package:assets_audio_player/assets_audio_player.dart';
class SoundManager {
static playSilencer() async {
final fileSilencer = "assets/sound/Gun_Silencer.mp3";
AssetsAudioPlayer player = AssetsAudioPlayer();
player.open(Audio(fileSilencer));
}
static playLuger() async {
final fileLuger = "assets/sound/Gun_Luger.mp3";
AssetsAudioPlayer player = AssetsAudioPlayer();
player.open(Audio(fileLuger));
}
}
就这样通过你想玩的地方:
SoundManager.playLuger();
这是我的代码:
