Flutter 音乐播放器案例

主要结构布局：

Stack(
        fit: StackFit.expand,
        children: [
          _buildVideo(),
          // 拖动组件
          const Positioned(
            left: 0,
            right: 0,
            top: 0,
            height: 120,
            child: DragToMoveArea(),
          ),

          /// 底部组件集合
          Positioned(
            left: 0,
            right: 0,
            bottom: 0,
            height: 120,
            child: Obx(
              () => SlideInUp(
                from: 120,
                duration: const Duration(seconds: 1),
                animate: controller.music.value != null,
                child: controller.music.value != null
                    ? Stack(
                        fit: StackFit.expand,
                        children: [
                          // 封面底图
                          Positioned(
                            left: 15,
                            bottom: 15,
                            child: _buildCoverBackground(),
                          ),
                          // 控制条
                          BlurWidget(
                            child: _buildControls(context),
                          ),
                        ],
                      )
                    : const SizedBox(),
              ),
            ),
          ),
          Positioned(
            right: 10,
            top: 10,
            child: Obx(
              () => SlideInRight(
                duration: const Duration(seconds: 1),
                animate: controller.music.value != null,
                child: _buildThemeButton(context),
              ),
            ),
          ),
        ],
      )

media-kit的一些事件订阅

 /// 监听事件
  StreamSubscription? subPlaying;
  StreamSubscription? subPlaylist;
  StreamSubscription? subPosition;
  StreamSubscription? subDuration;
  
    // 监听音乐回调
    subPlaying = _playerMusic.stream.playing.listen(onPlayingCall);
    subPlaylist = _playerMusic.stream.playlist.listen(onPlaylistCall);
    subPosition = _playerMusic.stream.position.listen(onPositionCall);
    subDuration = _playerMusic.stream.duration.listen(onDurationCall);
