  <h2>Issue</h2>
  <p>I've seen on <a href="https://packagist.org/packages/oro/platform#4.1.10" rel="nofollow noreferrer">Packagist</a> that OroPlatform 4.1.10 has the <code>symfony/symfony</code> dependency which contains <code>symfony/var-dumper: v4.4.13</code> and when I've tried to install it, I've got the following error message : <code>Package symfony/var-dumper is not installed</code></p>
