laravel custom classes add alias

Question

So I want to add a alias for custom classes in order to be able to use them in blade:

<?php
namespace App\Classes;

class Requirement
{
    public static function Test()
    {
        return "hello";
    }
} 

In config/app.php I added a alias like so:

...
'Requirement' => App\Classes\Requirement::class

Then, I would like to be able to call it in a blade template like

{{ Requirement::Test() }}

But the alias is not working somehow. I also tried composer dump-autoload, but it's still not working.

BTW: Is adding custom classes like that a viable way to implement site-specific logic like retrieving and processing data from a database or is there a better approach?

Edit 1

I created Requirement.php in app/Facades with following content

<?php
namespace App\Facades;
use Illuminate\Support\Facades\Facade;

class Requirement extends Facade{
    protected static function getFacadeAccessor() { return 'Requirement'; }
}

added PageContentProvider.php in app/Providers with the following content

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;

class PageContentProvider extends ServiceProvider
{
    /**
     * Register the application services.
     *
     * @return void
     */
    public function register()
    {
        $this->app->bind('Requirement', function($app){
            return new \App\Classes\Requirement();
        });
    }
}

and in config/app.php the alias

'Requirement'=>App\Facades\Requirement::class

as well as the provider

App\Providers\PageContentProvider::class

but it's still not working.

Edit 2

By adding something like

exit();

or

echo "blabla";

inside register(), nothing changes. Does that indicate that PageContentProvider is not even getting loaded?

Edit 3

Since the standard AppServiceProvider gets loaded, I deleted the coresponding entry of AppServiceProvider in config/app.php... and it still worked! Somehow my changes don't get applied. Does anybody have solution for that?

Answer 1

Problem wasn't the code at all: After realising that changes in config/app.php didn't get applied, a simple

php artisan config:clear

fixed literally every issue I presented in my question.

Answer 2

Add to your composer file:

"autoload": {
    //...
    "files" : ["app/classes/Requirement.php"]
},

Then add to your alias as you wrote in your config/app.php

Then you will be able to use in your templates:

{{ Requirement::test() }}
