Signup Link - link straight to signup (Flutter App)


I am trying to get a link that would guide users straight to the “Sign Up” instead of “Log in”. The problem I am running into is that each signup link has a (what appears to be) unique “state” value. Here is an example:

Is there a way to somehow standardize this value, or ensure it is the same every time in flutter app?

Hi All,
