The best solution would be IMHO to look at Twig's implementation of asset, which you can find in:

\Symfony\Bundle\TwigBundle\Extension\AssetsExtension

in the method:

public function getAssetUrl($path, $packageName = null, $absolute = false, $version = null)

which basically uses the templating.helper.assets service similar to @iamdto's answer:

$url = $this->container->get('templating.helper.assets')->getUrl($path, $packageName, $version);

Or directly use the AssetsExtension service or class respectively.
