Description

In this Flutter video tutorial, we take a look at the Firebase Auth plugin and how we can use it to anonymously sign in a user so that they have permissions to manipulate parts of our firebase database. Firebase offers many different providers for authenticating users. We can leverage this in our Flutter applications so that we do not need to build out our own authentication systems. We can also use the anonymous provider to work with a local authentication system. This could allow us to store usernames and password hashes into our firebase database to give our local authentication system a bit more security.

In this application, we just make two main page widgets, a login page and a home page. On the login page, the user can click on a button which will generate a unique user ID for the user and authenticate them to our Firebase database anonymously. This button also pushes the user to the home page which then displays some of the user properties. The user then can go back to the login page and click the sign out button to sign out from the Firebase database. We make use of various different widgets to build this application, including the material widget. The material widget is just a container widget with a specific set of properties which align with the material design specification.
