如何在flutter中设置支持背景和通知的简单音频播放器

dependencies:
  flutter_audio_service: ^0.17.0

import 'package:flutter_audio_service/flutter_audio_service.dart';

class MyAudioPlayer extends BaseAudioHandler {
  // 实现音频播放器的逻辑
}

class MyAudioPlayer extends BaseAudioHandler {
  @override
  Future<void> play() async {
    // 实现播放逻辑
  }

  @override
  Future<void> pause() async {
    // 实现暂停逻辑
  }

  @override
  Future<void> stop() async {
    // 实现停止逻辑
  }
}

void main() {
  AudioServiceBackground.run(() => MyAudioPlayer());
}

class MyAudioPlayer extends BaseAudioHandler {
  @override
  Future<void> play() async {
    // 设置通知
    AudioServiceBackground.setMediaItem(MediaItem(
      id: 'audio_1',
      title: 'Audio 1',
      artist: 'Artist 1',
      album: 'Album 1',
      duration: Duration(seconds: 60),
      artUri: Uri.parse('https://example.com/album_art.jpg'),
    ));

    // 设置背景
    AudioServiceBackground.setAndroidNotification(
      title: 'Audio 1',
      album: 'Album 1',
      artist: 'Artist 1',
      imageUrl: 'https://example.com/album_art.jpg',
    );

    // 实现播放逻辑
  }

  // 其他方法的实现
}
