[gianarb]

Now signature of method supports route params

$router = \FastRoute\simpleDispatcher(function (\FastRoute\RouteCollector $r) {
    $r->addRoute('GET', '/{id:\d+}', ['TestApp\Controller\Index', 'getSingle']);
});
$this->app = new \GianArb\Penny\App($router);

AppTest\Controller\Index

<?php
namespace TestApp\Controller;
use Zend\Diactoros\Request;
use Zend\Diactoros\Response;

class Index
{
    public function getSingle(Request $request, Response $response, $id)
    {
        $response->getBody()->write("id=$id");
        return $response;
    }
}
