Display screen to gather user information #142
Description
After a user registers, they will be asked to log in to the app. We need to provide a check in the login screen to check if the user that is logging in is a first-time user or an existing user.
If she/he is a first-time user, redirect the user to the InfoScreen which can be found in the screens folder. Gather information about the user and add it to Firebase Realtime Database.
For checking the type of user, you can use Firebase Realtime DB. Check if an entry for the UID of the user is there in the DB or not. If its not there, then this user is a first-time user.
