title: Fab button not working on a scroll view in react native
body: <p>Fab button is not working on a scroll view. I am using FAB from react-native-paper and the icon is displayed but when i press fab button, its not working. As an alternative, i tried to make a sticky button which sticks to the bottom when i use scroll view, but the button is displayed after the scrollview content and is not fixed at the bottom of our screen. It also fails.</p>
  <p>My code is like :</p>
  <pre><code>&lt;View&gt;
     &lt;FAB style={{position:'absolute',right:0,bottom:0}}/&gt;
     &lt;ScrollView&gt;&lt;/ScrollView&gt;
  &lt;/View&gt;
  </code></pre>
