Messaging apps have become an essential part of our daily lives, allowing us to easily communicate with friends, family, and colleagues. Over the years, they evolved significantly, from simple text messaging to video calling and more. However, as messaging apps have become more popular, concerns about privacy and security have also increased. Many messaging apps have been criticized for their lack of security and the potential for users' private data to be compromised.
### Objective
Build a secure mobile messaging app using Flutter and Firebase (or similar technologies). It should support either iOS, Android or both. The app should have biometric authentication, end-to-end encryption, and other security features to protect user data. Users should be able to send text messages, images, and videos, and create or join group chats.
### Instructions for Flutter and Firebase as a reference:
Set up a new Flutter project and integrate Firebase authentication and Cloud Firestore as a backend. Use the Firebase Console to create a new Firebase project, add appropriate configuration files.

Implement end-to-end encryption for secret chats using the encrypt or webcrypto packages. Use a symmetric encryption algorithm like RSA, and generate a new public and private key pair for each pair of users for each secret chat. The public keys should be securely shared between the sender and receiver.

- Messaging: Users should be able to send text messages, images, and videos, with features such as read receipts, typing indicators, and the ability to edit or delete messages.
- Secret chats: Users should be able to start encrypted one-on-one chats with the same functionality as regular chats with one exception: all messages have to be encrypted using an end-to-end algorithm.
### Bonus:
Group messaging: Users should be able to create or join group chats with multiple users having at least the same functionality as regular chats.
