问题
I want to build a PWA based on flutter web which relies on scanning a QR-Code and accessing the user's current position.
From my point of knowledge for both functionalities there are currently no packages available.
However for getting the user's location there is a stackoverflow thread (Get User's Location for flutter Web) providing a solution.
So I'm wondering if there is any chance that there is a similar solution for the QR-Scanning issue?
Sadly, I'm not very familiar with web and javascript development. So any help would be highly appreciated.

Following these two articels, I managed to use the jsQR Library in my flutter web application.

By this, I'm now able to scan a QR-code in flutter web.
