title: why my react native dotenv is not working?
body: <p>I want to use react-native-dotenv but its not working.</p>
  <p><a href="https://github.com/zetachang/react-native-dotenv" rel="nofollow noreferrer">https://github.com/zetachang/react-native-dotenv</a></p>
  <p>I created a .env file and added a FB_ID=21221</p>
  <p>then I go to babel and edited like this:</p>
  <pre><code>module.exports = function(api) {
    api.cache(true);
    return {
      presets: ['babel-preset-expo', 'react-native-dotenv'],
      plugins: ['react-native-reanimated/plugin'],
    };
  };
  
  </code></pre>
  <p>I restarted it and want to access FB_ID but its not exists</p>
