title: Flutter Just_audio, Error No implementation found for method disposeAllPlayers
body: <p>I am using <a href="https://pub.dev/packages/just_audio" rel="nofollow noreferrer">just_audio</a> package to play my base64 string which is a wav file that I received from my server. The app is being played from an android device API 30-ish. This is the error once the base64 is loaded:</p>

  <p>My custom base64 player which I follow from the instruction of the page:</p>
  <pre><code>class MyAudioPlayer extends StreamAudioSource {
    MyAudioPlayer({this.bytes});
  
    List&lt;int&gt; bytes;
  
    @override
    Future&lt;StreamAudioResponse&gt; request([int start, int end]) async {
      final start = 0;
      final end = bytes.length;
      return StreamAudioResponse(
        sourceLength: bytes.length,
        contentLength: end - start,
        offset: start,
        stream: Stream.value(bytes.sublist(start, end)),
        contentType: &quot;audio/x-wav&quot;,
      );
    }
  }
  </code></pre>
  <p>The file in which I played:</p>
  <pre><code>  void playTTS(String content) async{
      Dialogs.showLoadingDialog(context: context);
      final List&lt;int&gt; base64 = await ApiService.textToSpeech(content);
      final player = AudioPlayer();
      await player.setAudioSource(MyAudioPlayer(bytes: base64));
      await player.play();
      Navigator.of(context, rootNavigator: true).pop();
      listString.value = List.from(listString.value..add(ValueNotifier(content)));
    }
  </code></pre>
  <p>I have set already set this to my androidmanifest.xml to true already.</p>
  <pre><code>android:usesCleartextTraffic=&quot;true&quot;
  </code></pre>
  <p>Any help is appreciated.</p>
