How to use standard php package in Laravel? I try to import it but it can't be found?

I installed this Json Verification package:

https://github.com/justinrainbow/json-schema

It's just a PHP package it installs into vendor/justinrainbow/json-schema. I need to access it in my Code so I tried this in my Controller:

    use JsonSchema\Validator;

when I do this inside a method:

    $validator = new JsonSchema\Validator;

I get this error:

     Symfony\Component\Debug\Exception\FatalThrowableError  : Class 'App\Commands\JsonSchema\Validator' not found

Package has been installed with composer and is in the vendor folder.

How do I access it so that I can run some code that it shows on its GitHub page:

    $data = json_decode(file_get_contents('data.json'));
    
    // Validate
    $validator = new JsonSchema\Validator;
    $validator->validate($data, (object)['$ref' => 'file://' . realpath('schema.json')]);
    
    if ($validator->isValid()) {
        echo "The supplied JSON validates against the schema.\n";
    } else {
        echo "JSON does not validate. Violations:\n";
        foreach ($validator->getErrors() as $error) {
            echo sprintf("[%s] %s\n", $error['property'], $error['message']);
        }
    }

Once you imported the method using the use statement at the top of your file, you don’t need to use the whole paths of your class, just do

$validator = new Validator;

Or add a slash before the path, otherwise it looks relative to your current namespace (this is the case within the class, not for the use statement)

$validator = new \JsonScheme\Validator;

This also worked:

use JsonSchema\Validator as JsonValidator;

$validator = new JsonValidator;
