Programming Flutter

Building the Chat App

Now that we know how to use Firebase for what we need (authentication and database) and we have some more advanced UI notions, we can start building the chat app I promised we would work on.

Planning Our App’s UI

A chat app needs the user to perform multiple actions when they first start the app:

• We need the user to insert an email address and password and either log into an existing account or create a new one if they don’t have one yet, at this point the user should also receive an email asking him to verify his user account, but we’re not going to make distinctions between verified and unverified users at this point.

• We need the user to choose a display name to use to identify themselves to other users in the app.
