title: Flow “Required module not found” when importing a CSS file
body: <p>When I try to import CSS via webpack(import (./index.css)) I'm getting this error:</p>
  
  <pre><code>3: import './index.css';
            ^^^^^^^^^^^^^ ./index.css. Required module not found
  </code></pre>
  
  <p>I have a structure like ComponentName→(index.js, index.css), so that each component has all dependencies inside.</p>
  
  <p>I tried <a href="https://gist.github.com/lambdahands/d19e0da96285b749f0ef" rel="noreferrer">this</a> hack but it didn't work for me. Could I just ignore it somehow?</p>
