The right answer is : you shouldn't decorate UrlGeneratorInterface. You have to decorate 'router' service. Check here : https://github.com/symfony/symfony/issues/28663

** services.yml :

services:
    App\Services\MyRouter:
        decorates: 'router'
        arguments: ['@App\Services\MyRouter.inner']

** MyRouter.php :

router = $router;
    }

    /**
     * @inheritdoc
     */
    public function generate($name, $parameters = [], $referenceType = self::ABSOLUTE_PATH)
    {
        // Your code here

        return $this->router->generate($name, $parameters, $referenceType);
    }

    /**
     * @inheritdoc
     */
    public function setContext(RequestContext $context)
    {
        $this->router->setContext($context);
    }

    /**
     * @inheritdoc
     */
    public function getContext()
    {
        return $this->router->getContext();
    }

    /**
     * @inheritdoc
     */
    public function getRouteCollection()
    {
        return $this->router->getRouteCollection();
    }

    /**
     * @inheritdoc
     */
    public function match($pathinfo)
    {
        return $this->router->match($pathinfo);
    }
}
