Magento 2 : Adding logo in a custom extension

Question

I'm creating an extension where I should be able to call the logo which has been uploaded to Magento to show up in the home page.

So I upload the logo to:

Content -> Design -> Configuration -> Edit (Global) -> Header -> Logo Image

I have been investigating how Magento calls the logo:

vendor/magento/module-theme/Block/Html/Header/Logo.php

What would I need to add to my custom module in order to get this logo and show it. Thank you.

You need to inject \Magento\Theme\Block\Html\Header\Logo class in your block/controller and call getLogoSrc() method on its object to get the logo url and getLogoAlt() to get alt text.

Once you have it you can show it image tag in a phtml.
