title: Flutter NetworkImage vs cached_network_image
body: <p>Flutter recommends to use <code>cached_network_image</code> here <a href="https://flutter.dev/docs/cookbook/images/cached-images" rel="noreferrer">https://flutter.dev/docs/cookbook/images/cached-images</a>. I used it and it worked fine. I tried <code>NetworkImage</code> and it worked, too.</p>
  <p>I read from the doc that <code>NetworkImage</code> also caches the downloaded image locally. So what's the point in using <code>cached_network_image</code> instead of <code>NetworkImage</code>? Is there a comparison how their caching strategies differentiate from one another? Thanks!</p>
