I suggest you to use the Firebase dynamic links
Take a look at the following video, it should point you in the right direction
Firebase Dynamic Links
Dynamic Links are smart URLs that allow you to send existing and potential users to any location within your iOS or Android app. They survive the app install process, so even new users see the content they're looking for when they open the app for the first time.
For Flutter you can use this plugin Firebase Dynamic Links for Flutter
As soon as you have generated the link, it can be easily encoded in a qr-code image using an online service or an offline tool.
