                $session->put(self::SESSION_KEY, $request->getPreferredLanguage($this->languageRepository->getAllActive()->pluck('locale')->toArray()));
            }

            if (true === $request->has('lang')) {
                $lang = $request->get('lang');
                $check = $this->languageRepository->isLangActive($lang);

It seems like $lang can also be of type null; however, parameter $lang of PWWEB\Localisation\Repositories\LanguageRepository::isLangActive() does only seem to accept string, maybe add an additional type check?

                if (false === is_null($check)) {
                    $session->put(self::SESSION_KEY, $check->locale);
                }
            }

            app()->setLocale($session->get(self::SESSION_KEY));

The method setLocale() does not exist on Illuminate\Container\Container. Are you sure you never get this type here, but always one of the subclasses?

            return $next($request);
        }

        $lang = $request->server('HTTP_ACCEPT_LANGUAGE');

        app()->setLocale($lang);

        return $next($request);
    }
