Laravel and Local Tunnel integration - laravel

Question

My idea was to use Local Tunnel's subdomain feature to expose callback URI in a more convenient way. However, I believe that I could've achieved the same results in a simper way.
This is the solution with Laravel Valet:
In package.json I've added a script called shared
"scripts": {
...
"share": "lt --port 80 --subdomain blog --local-host blog.test"
}
In AppServiceProvider.php I've extended the UrlGenerator to avoid redirecting back to http://blog.test
<?php
namespace App\Providers;
use App\Services\LocalTunnelUrlGenerator;
use Blade;
use Illuminate\Http\Resources\Json\Resource;
use Illuminate\Routing\Router;
use Illuminate\Routing\UrlGenerator;
use Illuminate\Support\ServiceProvider;
class AppServiceProvider extends ServiceProvider
{
public function boot()
{
(...)
}
public function register()
{
$this->enableLocalTunnel();
}
private function enableLocalTunnel()
{
if (!app()->environment('local') || !config('app.use_local_tunnel')) {
return;
}
$this->app->extend('url', function (UrlGenerator $defaultGenerator) {
/** #var Router $router */
$router = $this->app['router'];
$routes = $router->getRoutes();
return new LocalTunnelUrlGenerator($routes, $defaultGenerator->getRequest());
});
}
}
This is the the LocalTunnelUrlGenerator.php:
<?php
namespace App\Services;
use Illuminate\Http\Request;
use Illuminate\Routing\RouteCollection;
use Illuminate\Routing\UrlGenerator;
class LocalTunnelUrlGenerator extends UrlGenerator
{
public function __construct(RouteCollection $routes, Request $request)
{
parent::__construct($routes, $request);
}
public function formatRoot($scheme, $root = null)
{
return "https://blog.localtunnel.me";
}
}
Why all that? Because whenever the application call the redirect() method, we are sent back to http://blog.test.
Do I really need to extend the UrlGenerator to make it work?
