codeigniter 4 page404

hii guys i try to make redirect to home page if the url is not defind / 404, but it not redirect

what i try is like this

in app/config/route.php

PHP Code:

<?php

namespace Config;

// Create a new instance of our RouteCollection class.
$routes = Services::routes();

// Load the system's routing file first, so that the app and ENVIRONMENT
// can override as needed.
if (file_exists(SYSTEMPATH . 'Config/Routes.php')) {
    require SYSTEMPATH . 'Config/Routes.php';
}

/*
 * --------------------------------------------------------------------
 * Router Setup
 * --------------------------------------------------------------------
 */
$routes->setDefaultNamespace('App\Controllers');
$routes->setDefaultController('DashboardController');
$routes->setDefaultMethod('index');
$routes->setTranslateURIDashes(false);
$routes->set404Override('App\Controllers\Page404Controller::index');
$routes->setAutoRoute(false);

/*
 * --------------------------------------------------------------------
 * Route Definitions
 * --------------------------------------------------------------------
 */

// We get a performance increase by specifying the default
// route since we don't have to scan directories.
$routes->get('/dashboard', 'DashboardController::index');
$routes->get('/', 'SigninController::index');

/*
 * --------------------------------------------------------------------
 * Additional Routing
 * --------------------------------------------------------------------
 *
 * There will often be times that you need additional routing and you
 * need it to be able to override any defaults in this file. Environment
 * based routes is one such time. require() additional route files here
 * to make that happen.
 *
 * You will have access to the $routes object within that file without
 * needing to reload it.
 */
if (file_exists(APPPATH . 'Config/' . ENVIRONMENT . '/Routes.php')) {
    require APPPATH . 'Config/' . ENVIRONMENT . '/Routes.php';
} 


and in app/Controllers/Page404Controller.php

PHP Code:

<?php

namespace App\Controllers;

use App\Controllers\BaseController;

class Page404Controller extends BaseController
{
    public function index()
    {
        // $args = $this->request->uri->getSegments();
        return redirect()->to('/');
    }
} 


Before version 4.2 this will not work.
You can use this solution.
By specifying the route last.

PHP Code:

$routes->addRedirect('(:any)', '/');

$routes = Services::routes();

// Load the system's routing file first, so that the app and ENVIRONMENT

if (file_exists(SYSTEMPATH . 'Config/Routes.php')) {

}

/*

$routes->get('/', 'SigninController::index');
$routes->get('/dashboard', 'DashboardController::index');
$routes->post('/authenticate', 'SigninController::authenticate');
