title: Tabs with scrolling animated header - React native
body: <p>I am following the tutorial in the link: <a href="https://medium.com/appandflow/react-native-scrollview-animated-header-10a18cb9469e" rel="nofollow noreferrer">https://medium.com/appandflow/react-native-scrollview-animated-header-10a18cb9469e</a> .
  However I can't seem to understand how to add tabs to this such that the tab headers get fixed to top when scrolled up. Can anyone please suggest how to achieve this?</p>
