title: React native maps mapPadding not working
body: <p>I'm using <code>fitToSuppliedMarkers()</code> for my markers and need to add some padding to my map. I have tried to implement <a href="https://github.com/react-community/react-native-maps/pull/1750" rel="nofollow noreferrer">this solution</a> with no luck. I can't use <code>fitToCoordinates()</code> because I need to create the markers in <code>componentDidMount</code> which that method doesn't support.</p>
  
  <p>My code:</p>
  
  <pre><code>&lt;MapView onMapReady={() =&gt; this.mapRef.map.setNativeProps({ padding: 100 })}&gt;&lt;/MapView&gt;
  </code></pre>
  
  <p>This code yields "setNativeProps is not a function".
  I have also tried using the <code>mapPadding</code> property that exists in the <a href="https://github.com/react-community/react-native-maps/blob/master/docs/mapview.md" rel="nofollow noreferrer">docs</a> with no luck: </p>
  
  <pre><code>&lt;MapView mapPadding={{top: 20, right: 20, bottom: 20, left: 20}}&gt;&lt;/MapView&gt;
  </code></pre>
