使用 preloadpageview 播放 15 到 20 个视频后，我在 flutter 中遇到内存不足错误

Question

我正在 flutter 中开发一个应用程序，我正在使用预加载页面视图和缓存的视频播放器插件通过我的数据库中的 url 播放视频，播放 15 到 20 个视频后，我的应用程序正在关闭并且 logcat提示这样的错误。我正在初始化 initstate 中的视频并处理视频小部件。

视频插件代码：

  @override
  void initState() {
    super.initState();
    controller = CachedVideoPlayerController.network(mediaUrl);
    _initializeVideoPlayerFuture = controller.initialize();
    controller.setLooping(true);
  }


  buildvideopreview(){
    return FutureBuilder(
      future: _initializeVideoPlayerFuture,
      builder: (context, snapshot) {
        if (snapshot.connectionState == ConnectionState.done) {
          return Stack(fit: StackFit.expand,
            children: <Widget>[
              AspectRatio(
                  aspectRatio: controller.value.aspectRatio,
                  child: VisibilityDetector(
                    key: Key(postId),
                    onVisibilityChanged: (VisibilityInfo info){
                      print("${info.visibleFraction} of my widget is visible");
                        if(info.visibleFraction == 1 && controller != null){
                          print('===========playing');
                            controller.play();
                          }
                        else{
                          print('============pause');
                          controller.pause();
                          }
                    },
                    child: CachedVideoPlayer(controller),
                  )
              ),
              Center(
                child: showheart
                    ? Image(
                  image: AssetImage('assets/gifs/heart.gif')
                )
                    : SizedBox()
              ),
              Center(
                  child: ispaused
                      ? Image(
                    width: 100,
                    height: 100,
                      image: AssetImage('assets/images/pause.png')
                  )
                      : SizedBox()
              )
            ],
          );
        } else {
          return Center(
            child: Container(
              width: 100,
              height: 100,
              child:
//              circularProgress(),
              Image(
                  image: AssetImage('assets/gifs/loadermain.gif')
              ),
            ),
          );
        }
      },
    );
  }

  @override
  void dispose() {
    super.dispose();
    postcontroller.dispose();
  }

主页（预加载综合浏览量）：

PreloadPageView.builder(
          scrollDirection: Axis.vertical,
          controller: postscontroller,
          preloadPagesCount: 5,
          itemCount: posts.length,
          physics: AlwaysScrollableScrollPhysics(),
          itemBuilder: (BuildContext context, int index) {
            Post post = posts[index];
            return post;
          });

Answer 1

当您看到异常时，您会认为您的应用程序占用了设备的大量 RAM。

您需要在 Flutter 应用程序中管理内存泄漏。

Android 和 iOS OS 为每个应用程序分配有限数量的 RAM，以便同时管理所有进程。

如果任何应用程序使用的 RAM 多于其分配的内存，OS 将停止该应用程序的所有进程。我们将其视为崩溃。

在您的情况下，您在应用程序中播放多个视频，并且所有视频都是捕获的视频。由于它们是捕获的视频，因此它们会暂时保存在 RAM 中，并且随着您看到越来越多的视频，您正在使用越来越多的 RAM。

您需要优化您的应用程序，页面更改后可以清除视频。

有了它，您可以控制内存泄漏。

使用 preloadpageview 播放 15 到 20 个视频后，我在 flutter 中遇到内存不足错误
