I currently have a Flutter mobile app that allows the user to authenticate to Firebase using an email link (password-less authentication). This implementation uses Dynamic Links. Since Google has deprecated Dynamic Links, I want to switch to Deep Links. However, I cannot find any documentation that does a good job of explaining how to acheive this.

The Firebase document for “Authenticate with Firebase Using Email Links” still makes reference to Dynamic Links

https://firebase.google.com/docs/auth/flutter/email-link-auth

I have successfully implemented deep links for other parts of the app e.g. share a image, etc, but I don’t know how to configure the URL created by the sendSignInLinkToEmail function to produce a deep link.
