QRCode

Hi Team

I am creating a back end for scanning qr code to payment, but the problem the qr code is not showing. But i have installed this library using a composer. The error i am getting is this "

Error: Call to undefined method Endroid\QrCode\QrCode::writeDataUri() in C:\wamp64\www\eCommerce\eshopper\eshopper-1.0.0\payments.php on line 19

"

What I have tried:

<?php
require 'C:\wamp64\www\vendor\autoload.php';

use Endroid\QrCode\QrCode;

// Process the payment and get the necessary data
$amount = $_POST['amount'];
$description = $_POST['description'];

// Generate the payment QR code
$paymentData = [
    'amount' => $amount,
    'description' => $description
];

$qrCode = new QrCode(json_encode($paymentData));
$qrCode->setSize(300);

$qrCodeDataUri = $qrCode->writeDataUri();

// Prepare the response
$response = [
    'qr_code_url' => $qrCodeDataUri
];

// Send the response as JSON
header('Content-Type: application/json');
echo json_encode($response);
?>
