  <p>I wanna remove the border that I highlighted in the above picture. I couldn't find any solution to fix this :(</p>
  
  <p>here is my SliverAppBar Code : </p>
  
  <pre><code>NestedScrollView(
          headerSliverBuilder: (BuildContext ctx, isScrolled) {
              return &lt;Widget&gt;[
                 SliverAppBar(
                    title: Text('Applying to this job opportunity'),
                    pinned: true,
                    titleSpacing: 0,
                    floating: true,
                    expandedHeight: 180,
                    flexibleSpace: //some widgets
               )
          ]
      }
  )
  </code></pre>
