Why cookie of laravel is null - 5.7

my cookie is null! But I don't know :

use Illuminate\Support\Facades\Cookie;

HomeController:

public function index()
{
    Cookie::queue('currentLang', 'heb', 999999999);



      $cat1         = $this->categoryRepo->findCategoryById(1);
      $lastPosts    = $this->blogPosts->listBlogPosts(array('*'),'id','desc')->take(3);

    return view('front.index', compact('cat1','lastPosts'));
}

now I want to get this key from another controller:

LoginController:

public function showLoginForm()
{
    dd(Cookie::get('currentLang'));
    return view('auth.login');
}

but it returns null ! I'm working on localhost.
