title: How to disable bottom SafeArea in child widget or change it's color?
body: <p>Is there a way to disable SafeArea at the bottom inside a child widget?</p>
  <p>If I have something like:</p>
  <pre><code>SafeArea(
     child: SecondWidget(),
  )
  </code></pre>
  <p>Is there a possibility to disable bottom part of the SafeArea in SecondWidget()? Or is there a way to set up background color only for the bottom part of the SafeArea?</p>
