Feature

• Chat rooms and history are based on account.

  • The first-time users can create an account by email, password, and a display name.

  • Users can create chat rooms by searching for others' email.

• The data are stored in Firebase.

  There are security rules set up for Firestore, so firebase_options.dart being public is okay.

  • Chat history can be restored at any device.

• Offline chat history.

  • Because the data is also stored in local database, the user can still access the chat history although there is no network.

• Chat with OpenAI.

  • A chat room with OpenAI will be created if it doesn't already exists.
