php artisan make:controller InvoiceController

<?php
namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Barryvdh\DomPDF\Facade\Pdf;



class InvoiceController extends Controller
{

    /**
     * Write code on Method
     *
     * @return response()
     */

    public function index(Request $request)

    {

        $data = [
            [

                'quantity' => 2,
                'description' => 'Gold',
                'price' => '0.00'

            ],

            [

                'quantity' => 3,
                'description' => 'Silver',

            ]

        ];



        $pdf = Pdf::loadView('invoice', ['data' => $data]);
        return $pdf->download();

    }

}
