flutter - 删除SliverAppBar底部边框-Flutter

我想删除上图中突出显示的边框。我找不到任何解决方案来解决这个问题:(

这是我的SliverAppBar Code:

NestedScrollView(
        headerSliverBuilder: (BuildContext ctx, isScrolled) {
            return <Widget>[
               SliverAppBar(
                  title: Text('Applying to this job opportunity'),
                  pinned: true,
                  titleSpacing: 0,
                  floating: true,
                  expandedHeight: 180,
                  flexibleSpace: //some widgets
             )
        ]
    }
)

最佳答案

只需将elevation属性设置为0即可。

 SliverAppBar(
                  title: Text('Applying to this job opportunity'),
                  pinned: true,
                  elevation: 0,
                  titleSpacing: 0,
                  floating: true,
                  expandedHeight: 180,
                  flexibleSpace: //some widgets
             )
