title: React Native Example App does not run in Expo Snack
body: <p>I'm learning React Native and trying to add a component to an Expo Snack for testing. I can't even get the example app to work though. </p>
  
  <p>Is it something different about how Snacks work vs. a desktop development environment? I've encountered that type of difference using JSFiddle, for example.</p>
  
  <p>I straight copy-pasted the code from the <a href="https://github.com/himelbrand/react-native-numeric-input/tree/master/Example" rel="nofollow noreferrer">Github repo</a> into <a href="https://snack.expo.io" rel="nofollow noreferrer">snack.expo.io</a> and it gave me an error: </p>
  
  <pre><code>Device: (946:881) Unable to resolve module 'module://expo-font.js'
    Evaluating module://expo-font.js
    Evaluating module://react-native-numeric-input.js
    Evaluating module://App.js
    Loading module://App.js
  </code></pre>
  
  <p>I've gotten this error before, but I've never been able to figure out why. Is it an issue with the package, which was updated just 7 days ago, or something else? Please advise.</p>
