use Dotenv\Dotenv;

class i18n
{
    /**
     * @var i18n|null
     */
    private static ?i18n $instance = null;

    /**
     * @return i18n
     */
    public static function getInstance () : i18n
    {
        if ( is_null( static::$instance ) ) {

Since $instance is declared private, accessing it with static will lead to errors in possible sub-classes; you can either use self, or increase the visibility of $instance to at least protected.

            static::$instance = new static;
        }

        return static::$instance;

The expression return static::instance could return the type null which is incompatible with the type-hinted return Coco\SourceWatcher\Utils\i18n. Consider adding an additional type-check to rule them out.
