Flutter chewie and videoplayer issue. Even after disposing the controllers , the video still keeps playing in the background, also tried pausing video

问题

这是我的Flutter应用程序代码，我遇到一个主要问题，即使关闭包含视频播放器的小部件并确保调用了dispose方法，视频仍然在后台播放，我不知道这个问题是否与chewie控制器或视频播放器有关。

甚至尝试在dispose时暂停视频，但没有效果，我甚至认为在使用此小部件多次的情况下暂停不是正确的选项，它会增加负载。

有人可以帮助我吗？

  String videoRootUrl = "";
  late VideoPlayerController videoPlayerController;
  late ChewieController chewieController;

  Future<String> fetchJsonContent() async {
    final jsonResponse = await http.get(Uri.parse(widget.jsonLink));
    if (jsonResponse.statusCode == 200) {
      var jsonContent = jsonDecode(jsonResponse.body);
      videoRootUrl = jsonContent["meta"]["rootUrl"];
      var files = jsonContent["files"];
      if (files.length > 0) {
        return videoRootUrl + files[0];
      }
      return "";

我尝试过处理和暂停视频，但没有效果。

英文:

Here is the code of my flutter app, I am facing a major issue that even after closing the widget that contains video player, making sure that dispose is being called , the video still keeps playing in the background don't know this issue is related to chewie controller or video player.

Even tried pausing the video on dispose but did not work, and I don't even think pausing is the right option incase i am using this widget multiple times it will increase the load.

Can any one help me with this???

Well I changed some things and now i am able to pause the player and dispose it - following are the things i changed- removed wantkeepAlive, removed future builder, changed dispose a bit and did not create any video player controller directly.

here is my code if anyone need it in future
