我正在使用flutter assets_audio_player包，它有一个错误。它正在播放多个音频，而不是替换现有音频。我尝试了许多方法来停止并在initState（）方法中播放，但没有工作。我不想处理它，因为我希望能够导航到其他屏幕，同时在后台播放音频。
如果我不处理音频示例，它在后台播放很好，但当我再次加载相同的音频时，它不会停止音频播放，而是开始播放多个音频。

import 'package:assets_audio_player/assets_audio_player.dart';

class AudioPlayer6Page extends StatefulWidget {
  const AudioPlayer6Page({super.key});

  @override
  State<AudioPlayer6Page> createState() => _AudioPlayer6PageState();
}

class _AudioPlayer6PageState extends State<AudioPlayer6Page> {
  late AssetsAudioPlayer assetsAudioPlayer;

  @override
  void initState() {
    // TODO: implement initState
    super.initState();
    assetsAudioPlayer = AssetsAudioPlayer.newPlayer();
    loadMedia();
  }

  Future<void> loadMedia() async {
    try {
      await assetsAudioPlayer.open(
          Audio.network(
              "https://s3.amazonaws.com/scifri-episodes/scifri20181123-episode.mp3"),
          autoStart: false,
          showNotification: true);
    } catch (t) {
      //mp3 unreachable
    }
  }

  @override
  void dispose() {
    // TODO: implement dispose
    super.dispose();

    print('dispose');

救命啊！
