How can one avoid displaying theme names in the front end of a widget while making changes to a WordPress theme in PHP?

To avoid displaying theme names in the front end of a widget while making changes to a WordPress theme in PHP, you can use the `get_option('stylesheet')` function to get the current theme's directory name. This way, you can dynamically retrieve the theme name without hardcoding it in the widget code.

$theme_name = wp_get_theme()->get('Name');
