颤振音频服务 ?? android.app.RemoteServiceException: Context.startForegroundService() 然后没有调用 Service.startForeground()

如何解决颤振音频服务 ?? android.app.RemoteServiceException: Context.startForegroundService() 然后没有调用 Service.startForeground()

在 Flutter 中，我使用 audio_service(Android/IOS) 插件在后台播放音频。

当我在后台显示的通知中单击 pause 、 play 或任何按钮时，该服务会引发以下错误。 这有什么问题吗？

pubspec.yaml 文件包括：

audio_session: ^0.0.10 
just_audio: ^0.6.9 
audio_service: ^0.16.2    
rxdart: ^0.24.1

================================================ ==========================

我在我的 androidManifest.xml 中添加以下标签

<uses-permission android:name="android.permission.WAKE_LOCK"/>
    <uses-permission android:name="android.permission.FOREGROUND_SERVICE"/>
<service android:name="com.ryanheise.audioservice.AudioService">
            <intent-filter>
                <action android:name="android.media.browse.MediaBrowserService" />
            </intent-filter>
        </service>

        <receiver android:name="com.ryanheise.audioservice.MediaButtonReceiver" >
            <intent-filter>
                <action android:name="android.intent.action.MEDIA_BUTTON" />
            </intent-filter>
        </receiver>

然后在我的班级中，我用这个指令调用我的播放器班

 Container(
        child: AudioServiceWidget(child:Player()),width: MediaQuery.of(context).size.width,)

我的播放器类包含此处列出的相同代码，但不同之处在于它在我的树小部件中，而不是在如下示例中的主要部件中： https://pub.dev/packages/audio_service/example

import 'dart:async';
    import 'dart:io';
    import 'dart:math';
    import 'package:audio_service/audio_service.dart';
    import 'package:audio_session/audio_session.dart';
    import 'package:flutter/foundation.dart';
    import 'package:flutter/material.dart';
    import 'package:just_audio/just_audio.dart';
    import 'package:rxdart/rxdart.dart';
    
    class Player extends StatelessWidget  {
    @override
    Widget build(BuildContext context) {
    return Scaffold(
    body: Center(
    child: StreamBuilder<bool>(
    stream: AudioService.runningStream,builder: (context,snapshot) {
                           ...........................
                           .............................
    } } }

    

现在，当我使用我的应用程序时，播放器可以工作，但是当我单击通知栏上方的按钮时，应用程序崩溃并出现以下错误。
