我的大部分后台代码都以 结尾MissingPluginException
,我不知道为什么,但我按照它所说的那样实现了一切;我尝试了所有可能的在线解决方案,但没有任何效果;现在,当我尝试使用 home_widget 插件从 android-home-widget 播放音频时,
我正面临着 audio_service插件;
最少的代码:
AudioPlayerTask audioPlayerTask;
void homeWidgetBackgroundCallback(Uri data) async {
WidgetsFlutterBinding.ensureInitialized();
if(audioPlayerTask == null) {
audioPlayerTask = AudioPlayerTask();
await AudioServiceBackground.run(() => audioPlayerTask);
}
AudioServiceBackground.state.playing ? audioPlayerTask.onPause() : audioPlayerTask.onPlay();
}
void main() async {
WidgetsFlutterBinding.ensureInitialized();
runApp(MyApp());
HomeWidget.registerBackgroundCallback(homeWidgetBackgroundCallback);
}
错误信息:

出现此错误的插件最多的是path_provider
插件,它永远不会在后台运行;
有什么建议吗?
