استدعاء ميثود غير معرفة في لارافيل

لدي الكود التالي في LocalizationController 

{
        App::setLocale($locale);
        Session::put('locale', $locale);

        return redirect()->back();
    }

وهذا في LocalizationMiddleware

public function handle(Request $request, Closure $next): Response
    {
        // Set Locale in this Middleware
        App::setLocale(session()->get('selected_language') ?? 'en');

        return $next($request);
    }

وهذا المسار

Route::get('locale/{locale}',[LocalizationMiddleware::class, 'setLanguage'])->name('locale');

وهذا كود blade

<div class="dropdown ms-1 topbar-head-dropdown header-item">
                    <button type="button" class="btn btn-icon btn-topbar btn-ghost-secondary rounded-circle" data-bs-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
                        <img id="header-lang-img" src="{{ asset('/') }}els/images/flags/us.svg" alt="Header Language" height="20" class="rounded">
                    </button>
                    <div class="dropdown-menu dropdown-menu-end">
                        <!-- English language -->
                        <a href="locale/en" class="dropdown-item notify-item language py-2" data-lang="en" title="English">
                            <img src="{{ asset('/') }}els/images/flags/us.svg" alt="user-image" class="me-2 rounded" height="18">
                            <span class="align-middle">English</span>
                        </a>
                        <!-- German Language -->
                        <a href="{{ url('locale/de') }}" class="dropdown-item notify-item language" data-lang="gr" title="German">
                            <img src="{{ asset('/') }}els/images/flags/germany.svg" alt="user-image" class="me-2 rounded" height="18"> <span class="align-middle">Deutsche</span>
                        </a>
                    </div>
                </div>

يظهر لدي الخطأ التالي

Call to undefined method App\Http\Middleware\LocalizationMiddleware::setLanguage() in Localization
