Flutter SingleChildScrollView not scrolling

Question

My singleChildScollView won't scroll vertically. I've checked similar questions regarding this problem but none of them sem to work for me. The page fills up with the items, and the homepage button is placed at the bottom...

...so it looks correct, it just doesn't let me scroll.

Scaffold(
    body: SingleChildScrollView(
               child: ListView.builder(
                           scrollDirection: Axis.vertical,
                           shrinkWrap: true,
                           itemBuilder: (ctx, index) {
                                  ...list of items here...
                           }
                      ),
          ),
)

Edit

Note in the example code above I have simplified the original widget tree and removed the homepage button.
