flutter - 当 listview.builder 是列表视图的子项时，如何使两个滚动控制器都处于活动状态？

Question

这里这个无限集合 ListView Widget 返回一个 listView。这里 listview.builder 用作 listview 的子项。如何使滚动小部件的两个控制器都能够在屏幕中设置动画或跳转

 Widget buildMessagesUsingProvider(BuildContext context) {
  return Consumer<List<GroupModel>>(
    builder: (context, groupList, _child) => Consumer<
            FirestoreDataProviderMESSAGESforGROUPCHAT>(
        builder: (context, firestoreDataProvider, _) =>
            InfiniteCOLLECTIONListViewWidget(
              scrollController: realtime,
              isreverse: true,
              firestoreDataProviderMESSAGESforGROUPCHAT:
                  firestoreDataProvider,
              datatype: Dbkeys.datatypeGROUPCHATMSGS,
              refdata: firestoreChatquery,
              list: Container(
                child: ListView.builder(
                    controller: _controller,
                    reverse: true,
                    padding: EdgeInsets.all(7),
                    physics: ClampingScrollPhysics(),
                    shrinkWrap: true,
                    itemCount: firestoreDataProvider.recievedDocs.length,
                    itemBuilder: (BuildContext context, int i) {
                      var dc = firestoreDataProvider.recievedDocs[i];

                      return buildEachMessage(
                          dc,
                          groupList.lastWhere((element) =>
                              element.docmap[Dbkeys.groupID] ==
                              widget.groupID));
                    }),
              ),
            )));
}
