Magento 2 Plugin on Magento\Store\Model\Store

Question

How to check if a plugin really work?

files are:

app/code/Vendor/Module/etc/di.xml

<?xml version="1.0" encoding="utf-8"?>
<config>
    <type name="Magento\Store\Model\Store">
      <plugin name="set_default_currency" type="Vendor\Module\Plugin\Store\Model\Store" disabled="false" />
    </type>
</config>

app/code/Vendor/Module/Plugin/Store/Model/Store.php

<?php
namespace Vendor\Module\Plugin\Store\Model;

class Store
{
    
    private $_logger;

    public function __construct(
        \Psr\Log\LoggerInterface $logger
    )
    {
        $this->_logger = $logger;
    }
    
    public function afterGetDefaultCurrencyCode(
        \Magento\Store\Model\Store $subject,
        $result
    )
    {
        $this->_logger->debug("GEOIP::".$result);
     }
     ....

The plugin seems to never been called.

The method Magento\Store\Model\Store->getDefaultCurrencyCode() is one in the Limitation of plugins?

Limitations

Plugins can not be used on following:

• Final methods
• Final classes
• Non-public methods
• Class methods (such as static methods)
• __construct
• Virtual types
• Objects that are instantiated before Magento\Framework\Interception is bootstrapped

EDIT

The reason was a silly typo mistake in registration.php file.

I want to add a note for those who find themselves in this situation.

My aim was to update the default currency based on the user's geo location.

Although it is a good method to create a plugin for the getDefaultCurrencyCode function, I ran into the issue of Full Page Cache, that literally drove me crazy.

Remembering the famous acronym "RTFM" I found an easy solution in: Configure page variations
