title: Hide createBottomTabNavigator Tabbar in React Native
body: <p>In <code>React Native 0.62</code> is it possible to hide on scroll the tabbar created with <code>createBottomTabNavigator</code> from <a href="https://reactnavigation.org/" rel="noreferrer">reactnavigation.org</a> ?</p>
  
  <p>I'm curious if it's possible in a similar way that LinkedIn has, when you scroll down the page the tabbar disappears and when you scroll back up it reappears. Or it's only possible with a custom tabbar?</p>
