title: How can we set a group of fonts using fontFamily props in React Native?
body: <p>As in css , we can set like this :</p>
  
  <pre><code>font-family:"Times New Roman",Georgia,Serif;
  </code></pre>
  
  <p>But in RN , we can just set one font ,</p>
  
  <pre><code>fontFamily: 'MidPlane00v3.1',
  </code></pre>
  
  <p>How can we use it like css?
