(string | WP_Screen) $screen The screen identifier. If you have used add_menu_page() or add_submenu_page() to create a new screen (and hence screen_id) make sure your menu slug conforms to the limits of sanitize_key() otherwise the 'screen' menu may not correctly render on your page.

The screen context for which to display meta boxes.

$data_object Gets passed to the meta box callback function as the first parameter. Often this is the object that's the focus of the current screen, for example a `WP_Post` or `WP_Comment` object.
