title: Flutter: single child scroll view is not working within positioned widget
body: <p>Here is an image of the component that I am trying to make scrollable:
  <img src="https://i.stack.imgur.com/pMPxZ.png" alt="component displaying &quot;Following&quot; with 5 user icons arranged sideways, fifth cut off but no scrollbar" />. The single child scroll view widget is not properly scrolling when I wrap it within a positioned widget. I need to have the positioned widget in order to properly align my components. How can I solve this issue?</p>
  <pre><code>Container(
              height: 130,
              padding: EdgeInsets.all(10),
              margin: EdgeInsets.all(10),
              decoration: BoxDecoration(
                color: Colors.grey[800],
                borderRadius: const BorderRadius.all(const Radius.circular(10)),
              ),
              child: Stack(
                children: [
                  Positioned(
                    top: 30,
                    child: SingleChildScrollView(
                      scrollDirection: Axis.horizontal,
                      child: ProfilePicScroll(),
                    ),
                  ),
                  Positioned(
                      left: 10,
                      child: Text(
                        'Following',
                        style:
                            TextStyle(fontWeight: FontWeight.bold, fontSize: 16),
                      )),
