title: I'm having problems with the react-native-maps ref
body: <p>I'm using a functionalComponente and using useRef in the MapView component. But the functions are not coming through the ref, does anyone know how to correct?</p>
  <p>code example</p>
  <pre><code>import React, {useRef} from 'react'       //version 16.13.1
  import MapView from 'react-native-maps'   //version 0.27.1
  import {View} from 'react-native'         //version 0.63.2
      
      const Map = () =&gt; {
      
          const mapRef = useRef(null);
      
          return (
             &lt;View&gt;
               &lt;MapView ref={mapRef}/&gt;
             &lt;/View&gt;
          )
      }
  </code></pre>
  <p>When I try to access mapRef.current, fitToCoodinates, getCamera, animateToRegion, etc ... are undefined. But I can get the props from mapRef.current.
  Can someone help me? I want the functions, not the properties.</p>
