Container(
              color: Colors.white,
              child: CustomScrollView(
                controller: scrollController,
                slivers: <Widget>[
                  /* (newsData?.news?.type != null && newsData?.news?.type == 2)
                      ? SliverToBoxAdapter(
                          child: Column(

                            ]),
                            topTitle()
                          ],
                        ))
                      : */
                  SliverToBoxAdapter(
                    child: Container(
                      height: 200,
                      child: Html(
                        data: newsData?.news?.abstract,
                        useRichText: true,
                      ),
                    ),
                  ),
_newsWidgets()
.....

newsWidgets is a sliverList.
I think problem is about it.
