Using SafeArea in Flutter : <p>I am trying to understand the <a href="https://docs.flutter.io/flutter/widgets/SafeArea-class.html" rel="noreferrer">SafeArea</a> widget in Flutter.</p>

<p>SafeArea code added to Flutter Gallery app <a href="https://github.com/flutter/flutter/pull/13593" rel="noreferrer">here</a> in github show   <code>top:false</code> and <code>bottom:false</code> everywhere. Why do these need to be set false in these cases?
