title: import { CardStyleInterpolators } from 'react-navigation-stack' is not working
body: <p>I'm using react-navigation <strong>4.0.10</strong> and react-navigation-stack <strong>1.10.3</strong> and trying to implement CardStyleInterpolations for android. According to the documentation <a href="https://reactnavigation.org/docs/4.x/stack-navigator" rel="nofollow noreferrer">https://reactnavigation.org/docs/4.x/stack-navigator</a> to implement this i have to do something like this</p>
  <pre><code>import { CardStyleInterpolators } from 'react-navigation-stack';
  
  // ...
  
  static navigationOptions = {
    title: 'Profile',
    cardStyleInterpolator: CardStyleInterpolators.forFadeFromBottomAndroid,
  }
  </code></pre>
  <p>and i'm implementing this with a functional component like this</p>
  <pre><code>Login.navigationOptions = () =&gt; {
    return {
      cardStyleInterpolator: CardStyleInterpolators.forFadeFromBottomAndroid,
    };
  };
  </code></pre>
  <p>because the static navigationOptions is for class component.</p>
  <p>that looks simple but it's throwing me an error <strong>undefined.object evaluating CardStyleInterpolators.forFadeFromBottomAndroid</strong> I guess this is related to incorrect import. Anyone knows how to implement it correctly.</p>
