In this tutorial series, we will create a quiz app using Flutter, Hasura, and Firebase. The first part focuses on setting up Hasura and modeling the relational data with permissions. Part 2 covers user authentication and integrating Firebase services, while Part 3 discusses building the Flutter frontend. We will explore how Hasura can work with Firebase Authentication and Cloud Functions to handle user authentication and business logic, providing a flexible and scalable architecture for our quiz app.
