composer require simplesoftwareio/simple-qrcode
Enter fullscreen mode Exit fullscreen mode

Register QR Code Service

You have to register the QR code services into the config/app.php file, so open the file and update the providers and alias array with the given below services.

<?php

    return [

    'providers' => [
        ....                
        SimpleSoftwareIO\QrCode\QrCodeServiceProvider::class,

        'QrCode' => SimpleSoftwareIO\QrCode\Facades\QrCode::class,

<?php

namespace App\Http\Controllers;

{
    public function index()
    {
      return view('qrcode');

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\QrCodeController;

/*

Route::get('/qrcode', [QrCodeController::class, 'index']);
Enter fullscreen mode Exit fullscreen mode
