Slim 3 routing to a controller best practice

I'm writing an app with Slim Framework 3, and I was wondering how I can achieve the following result.

I'm having many routes, and some of them can be satisfied by the same controller.

$this->slimApp->get('/', 'Controller\HomeController:home')->setName('home');
$this->slimApp->get('/test', 'Controller\HomeController:test')->setName('test');
And the HomeController has for example the method home():
public function home()
    // Do some stuff here... then render

The render() method comes from the BaseController (which HomeController extends).

While setting the routes, I'm also setting the following factories to have the HomeController have my main app object:

$this->slimApp->getContainer()['Controller\HomeController'] = function () {
    return new Controller\HomeController($this);
This lets me have in the controllers the main object of my app.

I was wondering, how can I pass the $request, $response and $arguments of a route as well? I'd like to have methods in my controllers that only takes care at most of the arguments they need (GET and POST params?) and $request and $response should go in the properties of the BaseController, so that I can use them if I really need them (render page in $response, or push CSRF tokens in it, coming from slim\csrf middleware)

Basically I'd like to avoid having to create controllers with tons of methods like this:

public function method1($req, $res, $args) {}
public function method2($req, $res, $args) {}
public function method3($req, $res, $args) {}

I'd prefer something more like this:

public function method1() {}
public function checkEmail($args) {}

The BaseController should take care of the request and response objects, pushing eventually CSRF tokens in the response, on top of what the more specific Controller would like to render.

I've been thinking at routing strategies and Middleware but I haven't found a clean solution yet.

Thank you!

    I solved this creating my own CallableResolver, implementing Slim\Interfaces\CallableResolverInterface and pushing it in the container of the app, key "callableResolver".

    Hi Jack,
    Would you mind sharing the skeleton of you solution?

    Sorry I didn't see the replies earlier. During the weekend I'll share with you the interested code, since the app now is not a skeleton anymore.

    Hi Jack Heuston, did you ever get a chance to post your CallableResolver? If so, could you share the link?
