Hello Mohammed Farook,
You can use: https://marketplace.mendix.com/link/component/118612
Just pass the content you want to convert as QR, it will be saved as image.
Hope my answer helps.
Yes what you could do is create a string deeplink url.
You could for example add a parameter in that as well for some data.
Then create a qr code of this string url using this widget: https://marketplace.mendix.com/index3.html
When you then read the QR code with this widget: https://docs.mendix.com/appstore/widgets/barcode-scanner/
The deeplink will get triggered and you can add the microflow logic in that deep link
