I am trying to make a app which uses the refer and earn system in which i want to assign the 6 digit unique code to each user. Is there any method which can create the 6 digit unique alphanumeric code to each user.

  • If by chance you are using firebase and are open to a id longer than 6 digits you can use the logged in user's uid. – Arsh Shaikh Aug 18 '20 at 16:55

You can either refer to this answer How to generate random string in dart?

Or if you are open to a legitimate solution but compromise over its length of six, I highly recommend you to please use uuid https://pub.dev/packages/uuid
