title: In React-Native, how can I choose an assets folder instead of another one based on my environment file?
body: <p>I'm building white label apps.</p>
  <p>I have an assets folder that contains one images folder and one fonts folder for each brands.</p>
  <p>Like so :</p>
  <pre><code>assets/
     brand1/
        fonts/
        images/
          img1.png
          img2.png
          img3.png
     brand2/
        fonts/
        images/
          img1.png
          img2.png
          img3.png
  src/
  </code></pre>
  <p>My idea would be to have an index.js at the root of the assets folder where I'd be able to export the relevant set of folders based on my environment file.</p>
  <p>Though I'm not sure how to achieve that.</p>
  <p>Any hint ?</p>
  <p>(My concern is that I don't want to have the environment conditioning in each of my components)</p>
