The tutor app will have users log in or sign up using Firebase Authentication, and it will have the state of the user managed and updated using Riverpod and Firebase Cloud Firestore. The main feature of the tutor app is the ability to have video call lessons between teachers and students. The app uses Agora for real-time communication, allowing users to create sessions, pay for them, and join or start video calls. The app also includes features such as cloud recording and real-time transcription, which can be accessed through a list view in the settings section. Additionally, the app has an Apple Pay feature that allows users to make payments using their Apple devices.
