在ListView中使用时发生FadeInImage错误

如何解决在ListView中使用时发生FadeInImage错误

setState() called after dispose(): _ImageState#46191(lifecycle state: defunct,not mounted,stream: ImageStream#75f5c(MultiFrameImageStreamCompleter#f16d5,[250×130] @ 1.0x,2 listeners),pixels: null,loadingProgress: null,frameNumber: null,wasSynchronouslyLoaded: false)


This error happens if you call setState() on a State object for a widget that no longer appears in the widget tree (e.g.,whose parent widget no longer includes the widget in its build). This error can occur when code calls setState() from a timer or an animation callback.

The preferred solution is to cancel the timer or stop listening to the animation in the dispose() callback. Another solution is to check the "mounted" property of this object before calling setState() to ensure the object is still in the tree.
This error might indicate a memory leak if setState() is being called because another object is retaining a reference to this State object after it has been removed from the tree. To avoid memory leaks,consider breaking the reference to this object during dispose(). >>> #0      State.setState.<anonymous closure> (package:flutter/src/widgets/framework.dart:1197:9)

我在ArrayList中有300多张图片。 但是我以20的卡盘加载到ListView。

但是，每当我使用某些搜索查询过滤列表时，都会遇到此问题，导致白色背景而不是实际图像。

下面是我的加载图片的代码

Container(
            width: double.infinity,child: FadeInImage.assetNetwork(
              placeholder: 'assets/loading_image.png',image: Util.getImageUrl(item.business_featured_image),height: 130,imageErrorBuilder:
                  (BuildContext context,Object y,StackTrace z) {                    
              return Image(
                  image: NetworkImage(
                      Util.getImageUrl(item?.business_featured_image)),fit: BoxFit.cover,errorBuilder:
                      (BuildContext context,StackTrace z) {                       
                    return Center(
                        child: Icon(
                          Icons.broken_image,size: 120,color: colorLightGrey,));
                  },);
              },imageCacheHeight: 130,imageCacheWidth: 250,),)

我也在检查挂载和处置属性

if (!_isDispose && mounted) { setState(() { log("setState calling : "); mainList = value; }); _increasePageSize(); }

此错误已经在我的网站上吃了2天，请提供帮助。 过去2年以来，Flutter Github帐户中列出了相同的错误，但仍未修复。
