Firebase Auth & Analytics for Flutter

I have firebase installed with firebase auth and analytics set up. However, I want to fine tune both by collecting the user's name & photo at sign up / log in and implement a more detailed analytics set up so I can see each screen the user visits from login to logout.

**It's important that I work with a developer who knows how to communicate well and pays attention to details and stays on time. So please to submit a thoughtful proposal. Thanks
