Group route middleware not being called - php

Question

What I'm trying to do is group multiple prefixes with one middleware:
Route::group(['middleware' => ['centralize']], function () {
Route::group(['prefix' => \App\Utilities\Centralization::setLocale()], function () {
Route::group(['prefix' => \App\Utilities\Centralization::setCountry()], function () {
Route::group(['prefix' => \App\Utilities\Centralization::setCity()], function () {
Route::group(['prefix' => \App\Utilities\Centralization::setArea()], function () {
//routes
});
});
});
});
});
I have added the centralize middleware to kernel:
protected $routeMiddleware = [
...
'centralize'=> \App\Http\Middleware\Centralize::class,
...
];
But the middleware is not being called at all, is there is something missing here?
EDIT: it goes directly to the view of the home, I am doing dd inside of the middleware but it never reaches there!
EDIT: middleware code:
<?php
namespace App\Http\Middleware;
use App\Utilities\Centralization;
use Closure;
use Illuminate\Http\RedirectResponse;
class Centralize
{
/**
* #var \Illuminate\Http\Request
*/
private $request;
/**
* #var array
*/
private $params;
private $location;
/**
* Handle an incoming request.
*
* #param \Illuminate\Http\Request $request
* #param \Closure $next
* #return mixed
*/
public function handle(\Illuminate\Http\Request $request, Closure $next)
{
$this->request = $request;
dd('hit');
$this->params = explode('/', $request->getPathInfo());
$this->figureLocale();
$this->figureCountry();
$this->figureCity();
$this->figureArea();
$this->figureLocation();
$redirection = implode('/', $this->params);
if ($request->getPathInfo() !== $redirection) {
return new RedirectResponse($redirection, 302, ['Vary' => 'Accept-Language']);
}
\View::share([
'countries' => Centralization::getCountries(),
'cities' => Centralization::getCities(),
'areas' => Centralization::getAreas(),
'location' => $this->location
]);
return $next($request);
}
private function figureLocale()
{
//...
}
private function figureCountry()
{
//..
}
private function figureCity()
{
//...
}
private function figureArea()
{
//...
}
private function figureLocation()
{
//...
}
}
EDIT: I also have tried:
Route::middleware(['centralize'])->group(function () {
Route::group(['prefix' => \App\Utilities\Centralization::setLocale()], function () {
Route::group(['prefix' => \App\Utilities\Centralization::setCountry()], function () {
Route::group(['prefix' => \App\Utilities\Centralization::setCity()], function () {
Route::group(['prefix' => \App\Utilities\Centralization::setArea()], function () {
//..
});
});
});
});
});
But with the same result , it never hits the middleware!
EDIT: clearing cache using artisan and manual doesn't work either!

Group route middleware called like this:
In routes/web.php
Route::group(['middleware' => ['centralize']], function () {
Route::group(['prefix' => \App\Utilities\Centralization::setLocale()], function () {
Route::group(['prefix' => \App\Utilities\Centralization::setCountry()], function () {
//routes
});
});
});
In app/Http/kernal.php
protected $routeMiddleware = [
'centralize' => \App\Http\Middleware\CentralizeMiddleware::class,
];
In app/Http/Middleware/CentralizeMiddleware.php
<?php
namespace App\Http\Middleware;
use Closure;
use Illuminate\Support\Facades\Auth;
class CentralizeMiddleware
{
public function handle($request, Closure $next)
{
if (//Your Condition) {
//If true
}
else {
return $next($request);
}
}
}

You mentioned in one edit that:
it goes directly to the view of the home
So the URL you are visiting is actually /. And as clarified in the comments, the "home" route was defined nested inside the prefixes. But that means it is really a route for something like /fr/france/paris/somewhere/, and not a route for /.
The prefix in the route means "this route applies to URIs with this prefix". If a URI does not include that prefix, this routing is not applied.
So that means there is no route for /, and visiting it will:
not fire the centralize middleware;
not find a matching route, so throw a 404;
If you want to apply your centralize middleware to your home route, you'll need to place it inside that group, but outside the prefixes:
Route::middleware(['centralize'])->group(function () {
Route::get('/', 'HomeController#index')->name('home');
Route::group(['prefix' => \App\Utilities\Centralization::setLocale()], function () {
// ...
});
});
