Correct way to handle meta tags

I have a project where I have a default description meta tag, but in some pages I want o set a custom description meta tag.

At the moment I have this on my layout file:

<?php $this->registerMetaTag(['name' => 'description','content' =>'DEFAULT DESCRIPTION'], 'description');?>

and on some views I have the same code

<?php $this->registerMetaTag(['name' => 'description','content' =>"CUSTOM DESCRIPTION"], 'description');?>

The problem is that the layout file is handle after the view file so I will always get the default description. What is the correct way to handle this?

You can use the params property of the view component for it.

Exactly this seams to be one solution.
