 This is the first of a series of Flutter Tutorials. During the series, you will learn how to build cross-platform apps without worrying about the backend.
 
 In the first part, I will show you how to build a chat application, where users can sign up and talk to other users in a single chat room. The exchange of messages will happen in real time, meaning that you do not have to refresh the page to load new messages.
