Custom Welcome Widget in all themes

Hello,

I'm using a custom welcome widget. I have added the code to my themes function.php. I noticed that when I change the theme the welcome widget doesn't appear - obviously as the active function.php file has changed. Is there a way to make the widget appear always no matter which theme is activated?

<?php

// DASHBOARD WELCOME WIDGET

function register_raccoonbox_ohjauspaneeli_vimpain() {
    global $wp_meta_boxes;

    wp_add_dashboard_widget(
        'raccoonbox_ohjauspaneeli_vimpain',
        'Tervetuloa mahtavalle sivullesi!',
        'raccoonbox_ohjauspaneeli_vimpain_display'
    );

    $dashboard = $wp_meta_boxes['dashboard']['normal']['core'];

    $my_widget = array( 'raccoonbox_ohjauspaneeli_vimpain' => $dashboard['raccoonbox_ohjauspaneeli_vimpain'] );
    unset( $dashboard['raccoonbox_ohjauspaneeli_vimpain'] );

    $sorted_dashboard = array_merge( $my_widget, $dashboard );
    $wp_meta_boxes['dashboard']['normal']['core'] = $sorted_dashboard;
}
add_action( 'wp_dashboard_setup', 'register_raccoonbox_ohjauspaneeli_vimpain' );

function raccoonbox_ohjauspaneeli_vimpain_display() {
    ?>

  <a href="http://raccoonbox.com" target="_blank"><img src="http://raccoonbox.com/raccoonbox-img/RACCOONBOX-logo_200.png" alt="Raccoonbox logo" width="100px" height="100px"></a>

    <p>
       Lorem
    </p>
    <p>
       Lorem
    </p>

    <?php
}

// EDIT ADMIN FOOTER

add_filter('admin_footer_text', 'remove_footer_admin'); //change admin footer text
function remove_footer_admin () {
echo 'Kiitos kun valitsit <a href="http://raccoonbox.com">Raccoonboxin</a> | Muotoilija <a href="http://raccoonbox.com/muotoilijat">Konstantin Nikkari</a';
}

?>

Yes, you most certainly can. The best way to do that is to create your own plugin that uses the code you have for the widget. There is a WordPress feature called Must Use Plugins, which are installed into a different directory, and are available to all themes.

Must Use Plugins: https://codex.wordpress.org/Must_Use_Plugins

Here is a tutorial showing how to make a widget plugin, you can probably just take the code you have an wrap it in the plugin functionality and get it going fairly easily:
