title: What is the difference between a Stack and a Column in Flutter?
body: <p>I'd like to know what are the differences between a <code>Stack</code> and a <code>Column</code> in Flutter? I know that both widgets are responsiple for stacking Widgets on top of each other I'm a bit confused when to use a <code>Stack</code> and when to use a <code>Column</code>?</p>
  <p>I also know that a <code>ListView</code> is scrollable either horizontally or vertically and therefore distinguishes from a <code>Column</code> and a <code>Stack</code>. But neither the <code>Stack</code> nor the <code>Column</code> is scrollable.</p>
  <p>So what is the difference between these two?</p>
