title: Can I store or cache images locally in React Native?
body: <p>I have a news app and I want to store the images locally when first gets them.</p>
  
  <p>React Native's AsyncStorage accepts key-value string data. Can I use it?</p>
  
  <p>In browser I was using <code>canvas</code> to get the data uri or<code>BlobBuilder</code> to get BLOB, not sure if it works in React Native.</p>
