title: crossAxisAlignment.stretch making everything invisible
body: <p>I want to align stretch my buttons on the Card child but somehow it is making everything invisible
  The main problem is I want the buttons to be evenly matched on their width.</p>

  <p>For now I set it to [start] as my widgets become invisible when it is on stretch.
  I also added a background image but I don't know if that is the reason why the stretch is not working.</p>
