Cart system made in php - php

Question

So I keep getting this error from my app.php and have no clue whats going on. I am following a tutorial about how to make a shop cart in php. I will leave the code and error text and maybe you guys have an idea.
Error text :
Fatal error: Uncaught Error: Class 'Cart\App' not found in
C:\xampp\htdocs\cart\bootstrap\app.php:11 Stack trace: #0
C:\xampp\htdocs\cart\public\index.php(3): require() #1 {main} thrown
in C:\xampp\htdocs\cart\bootstrap\app.php on line 11
To save you some time the error is coming from $app = new App;
Code :
<?php
use Cart\App;
use Slim\Views\Twig;
use Illuminate\Database\Capsule\Manager as Capsule;
session_start();
require __DIR__ . '/../vendor/autoload.php';
$app = new App;
$container = $app->getContainer();
$capsule = new Capsule;
$capsule->addConnection([
'driver' => 'mysql',
'host' => 'localhost',
'database' => 'cart',
'username' => 'root',
'password' => '',
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => ''
]);
$capsule->setAsGlobal();
$capsule->bootEloquent();
Braintree_Configuration::environment('sandbox');
Braintree_Configuration::merchantId('MERCHANT_ID');
Braintree_Configuration::publicKey('PUBLIC_KEY');
Braintree_Configuration::privateKey('PRIVATE_KEY');
require __DIR__ . '/../app/routes.php';
$app->add(new \Cart\Middleware\ValidationErrorsMiddleware($container->get(Twig::class)));
$app->add(new \Cart\Middleware\OldInputMiddleware($container->get(Twig::class)));

Answer 1

The use statements must be AFTER the import of autoload.php
