How Can I generate QR code and Show it on a PDF page in Flutter

I am Building a Flutter App, and one of the Functionalities includes the following:

1- Generating Qr codes - no problem here if I am showing it on the screen. 2- Generating PDF file, then saving it and sharing it using native device Sharing, No problem here until I tried to include the Qr code in the PDF page!

I have been stuck with this for two days and tried too many approaches to solve this, sadly with no luck.

please help and thank you all in advance.

using this package (pdf package) you can use like this -->

final pdf = pw.Document();    
pw.BarcodeWidget(
        data: "demo",
        barcode: pw.Barcode.qrCode(),
        width: 100,
        height: 50
    ),

result is:

You can use the Barcode widget from the pdf package. https://pub.dev/packages/pdf

import 'package:pdf/widgets.dart' as pw;

//Barcode widget inside pdf.addPage()
pw.BarcodeWidget(
  color: PdfColor.fromHex("#000000"),
  barcode: pw.Barcode.qrCode(),
  data: "My data",
),

I have got the following answer from DavBfr / dart_pdf on GitHub and it worked:

Yes, there is a Widget for that:

BarcodeWidget( barcode: Barcode.qrCode(), data: 'here is a qrcode', )

You can use the same widget for Flutter too: https://pub.dev/packages/barcode_widget
