title: null is not an object (evaluating 'RCTToastAndroid.SHORT')
body: <p>I am attempting to convert my react-native project into an expo project, one small issue I've encountered is when I run the expo project I get an error as such </p>
  
  <p><code>null is not an object (evaluating 'RCTToastAndroid.SHORT')</code></p>
  
  <p>After doing some research online on how to fix this problem a user requested that a problem like this can simply be resolved by removing the <code>Android</code> part of <code>RCTToastAndroid.SHORT</code> this user stated that <code>RCTToast</code> is universally compatible with both iOS and Android. However when I do this I receive an error saying <code>null is not an object (evaluating 'RCTToast.SHORT')</code> </p>
  
  <p>What can I do that will help ease the transition from my react-native project to an expo project?</p>
