title: flutter move floatingActionButton up 50 pixels
body: <p>Is it possible to move the <code>floatingActionButton</code> up by <em>50</em> pixels?</p>
  
  <p>I have a <code>floatingActionButton</code> in an App that uses <code>firebase_admob</code> and the Ads Banner is overlapping on top of the <code>floatingActionButton</code>.</p>
  
  <p>How does one set the <code>floatingActionButton</code> to be <em>50</em> <em>pixels</em> from the bottom of the screen?</p>
  
  <p>From the <a href="https://docs.flutter.io/flutter/material/FloatingActionButton-class.html" rel="noreferrer">documentation</a> of <code>floatingActionButton</code> I can not seem to pick out how to position the button.</p>
