Hi guys, I want to build a referral program wherein current users are rewarded for inviting friends to join my app/website. I also wanted to keep the accounts linked so that recruiting users can get rewarded every time a new user they recruited purchases something. I want to just give the users points, I'm not offering cash or subscription discounts. similar to how game invites work. through my research into the topic I have found dynamic links with flutter and firebase. deep deferred links, QR code deferred links, and some work around that included taking the user to a website copying the code to their clipboard, then pasting it into a hidden textfield to verify and track the code can anyone help me get started?
