Flutter 颤振Swiper（视频）

我一直在使用

flatter_swiper

package来实现一个旋转木马效果，以查看多个图像，它工作正常

现在，我一直计划实现一个旋转木马效果来观看多个视频

我一直在用

chuwie

观看一段视频，而且效果也不错

然后我尝试将两者结合起来，但效果并没有尽可能一致

首先，您可以在

Swiper

中查看所有视频。但当你继续来回滑动时，就会出现一个错误

“错误（处理后使用了VideoPlayerController。 在VideoPlayerController上调用dispose（）后，将无法再使用它。）“

我真的需要你的帮助

这是我的朱伊：

class ChewieFeedItem extends StatefulWidget {
  // This will contain the URL/asset path which we want to play
  final VideoPlayerController videoPlayerController;
  final bool looping;

  ChewieFeedItem({
    @required this.videoPlayerController,
    this.looping,
    Key key,
  }) : super(key: key);

  @override
  _ChewieFeedItemState createState() => _ChewieFeedItemState();
}

class _ChewieFeedItemState extends State<ChewieFeedItem> {
  ChewieController _chewieController;
  bool isPlaying = false;
  @override
  void initState() {
    super.initState();
    // Wrapper on top of the videoPlayerController
    _chewieController = ChewieController(
      videoPlayerController: widget.videoPlayerController,
      aspectRatio: widget.videoPlayerController.value.aspectRatio,
      // Prepare the video to be played and display the first frame
      autoInitialize: true,
      looping: widget.looping,
      showControls: false,
      autoPlay: false,
      // Errors can occur for example when trying to play a video
      // from a non-existent URL
      errorBuilder: (context, errorMessage) {
        return Center(
          child: Text(
            errorMessage,
            style: TextStyle(color: Colors.white),
          ),
        );
      },
    );
  }

  @override
  Widget build(BuildContext context) {
    return Container(
      width: MediaQuery.of(context).size.width,
      height: MediaQuery.of(context).size.height,
      child: Stack(
        children: <Widget>[
          Chewie(
            controller: _chewieController,
          ),
          Container(
            alignment: Alignment.center,
            child: GestureDetector(
              onTap: () {
                if (isPlaying) {
                  _chewieController.pause();
                  setState(() {
                    isPlaying = false;
                  });
                } else {
                  _chewieController.play();
                  setState(() {
                    isPlaying = true;
                  });
                }
              },
              child: Icon(
                isPlaying ? FontAwesomeIcons.pause : FontAwesomeIcons.play,
                size: 80,
                color: Color(colorProxiWall).withOpacity(0.3),
              ),
            ),
          ),
        ],
      ),
    );
  }

  @override
  void dispose() {
    super.dispose();
    // IMPORTANT to dispose of all the used resources
    widget.videoPlayerController.dispose();
    _chewieController.dispose();
  }
}

我正在将内容传递到

getImageType

，以检查内容是

图像还是
视频
我的脚本是否适合我

Scaffold _scaffold(ProductDetailApi data, Size size){
videoPlayerController = VideoPlayerController.network(data.gallery[1].url);
chewieController = ChewieController(
  videoPlayerController: videoPlayerController,
  aspectRatio: 3 / 2,
  autoPlay: true,
  looping: true,
);
return Scaffold(
  resizeToAvoidBottomPadding: false,
  appBar: AppBar(
    title: Text(data.products[0].productname),
    backgroundColor: Colors.lightBlue,
  ),
  body: Column(children: <Widget>[
    //buildImage(data, size),
    //buildVideo(chewieController, size),
    //_swiper(data, size),
    Container(
              // A fixed-height child.
              height: 150.0,
              child: _swiper(data, size),
            ),
    buildSubmitBid(),
    buildDescription(data),
    SizedBox(height: 10,),
    buildChoice(data),
    buildLastBidTitle(),
    Expanded(
      flex: 2,
      child: buildLastBid(data),
    ),
    SizedBox(height: 10,),
    Container(
      margin: EdgeInsets.fromLTRB(10, 0, 10, 0),
      child: 
          Row(
            crossAxisAlignment: CrossAxisAlignment.start,
            children: <Widget>[
              Text(data.products[0].description,
                  style: TextStyle(
                    fontSize: 15
                  ),
              )
            ]
          )
      )
  ],)
);

}
嗨，你能解决这个问题吗？我已经使用了你的类和视频加载在我的旋转木马，但我得到一个内存泄漏的视频播放控制器。网络。一些帮助将不胜感激。
