Widget _buildListView(ThemeData theme) {
    Widget resultWidget = ListView.builder(
      physics: ChatObserverClampinScrollPhysics(observer: chatObserver),

请提供完整的可复现问题代码

代码比较多

  // 初始化的
  @override
  void initState() {
    super.initState();
    chatInfoListPageController = widget.chatInfoListPageController;
    state = chatInfoListPageController.state;
    scrollController.addListener((){

    });
    observerController = ListObserverController(controller: scrollController)
      ..cacheJumpIndexOffset = false;
    //observerController.jumpTo(index: index);
    chatObserver = ChatScrollObserver(observerController)
    //..fixedPositionOffset = 5
      ..toRebuildScrollViewCallback = () {
        setState(() {});
      }
      ..onHandlePositionResultCallback = (result) {
    
      };}

//插入信息
  insertOrUpDataMessage(ListElement history,{required int index,bool? isInsert,bool? isJump=false}) async{
    await MessageDao.insertMessage(history.copyWith(chatUuid: state.chatRoomInfo.chatUuid),state.chatRoomInfo.chatType);
    chatObserver.standby();
    var h= await MessageDao.getMessageByUuid(history.messageUuid);
    if(h!=null){
      if(isInsert==true){
        state.recordList.insert(index, h.toListElement());
      }else{
        state.recordList[index]=h.toListElement();
      }
      if(isJump==true){
        jumpTo(index);
      }
      update(["chatRoomList"]);
    }
  }
//发送插入信息
    var preMessage= ListElement(messageData: messageData, messageUuid: startTimestamp.toString(), timestamp: startTimestamp, messageType: messageType,
        userUuid: UserStore.to.userUuid,userAvatar: UserStore.to.getLoadUserInfo()?.avatar,sendState: 1,userName: UserStore.to.getLoadUserInfo()?.name);
    if(messageType==ChatDataMessageTypeCache.text.value&&state.quoteMessage!=null){
      preMessage=preMessage.copyWith(
          quoteChatRecord:state.quoteMessage
      ) ;
    }
    
    chatObserver.standby();
    state.recordList.insert(0, preMessage);
     updatePage();
    // jumpTo(0);
我已经在插入信息的时候都调用了 chatObserver.standby(); 移除的时候使用 chatObserver.standby(isRemove: true);还有就是调用jumpTo会失效 
 if (index <= state.recordList.length - 1) {
        itemScrollController?.jumpTo(index: index);
        if (index == 0) {
          showDownBtn(false);
        }
        state.isFirst = false;
      }

光看上面给出的代码我无法定位问题，代码中有你自己定义的类型，我无法直接运行去调试。

是否可以基于示例代码去调整，然后给出可复现、可运行的完整代码？

[fjjpydc]

可能是我使用了Image.file和CachedNetworkImage切换的原因？

[LinXunFeng]

这种情况看起来跟 scrollview_observer 没有关系，scrollview_observer 只是在观察后调整了一下滚动视图的偏移量而已。

你可以试试看不使用 scrollview_observer 的情况下还会不会

控件加了key可以了
