wordpress-plugin-css-cache-buster.php

/* 
    Add custom stylesheet into plugin admin.
    This method appends the plugin version number to the stylesheet for easy CSS cache busting.

    If your plugin is at version 1.0 the styesheet URL will look like this: 
    https://example.com/wp-content/plugins/your-plugin/css/your-plugin-style.css?ver=1.0

    Any time you update your plugin version number, the query string value will match it.
