title: Creating Directory in Flutter
body: <p>I've looked this question on the web but there isn't any &quot;direct&quot; answer to it that was suitable to me. My app is downloading some videos from the url typed in a <code>TextField</code>. I'm using <code>flutter_donwloader</code> package. The error displayed because I haven't created a directory is:</p>
  <pre><code> 'package:flutter_downloader/src/downloader.dart': Failed assertion: line 70 pos 12:
   'Directory(savedDir).existsSync()': is not true
  </code></pre>
  <p>I want to save it in the Downloads folder. I actually don't know how to create a directory and this is why I haven't been able to understand other answers. Please help guys.</p>
