Beauty LMS Frontend

This repository contains two frontends for the Beauty LMS video conferencing system:

1. React TypeScript Frontend (in src/ directory) - Original web-based implementation
2. Flutter Frontend (in flutter_app/ directory) - Cross-platform mobile and web application

🎯 Flutter App (Recommended)

The Flutter application provides the same functionality as the React frontend but with cross-platform support for Android, iOS, and Web.

Quick Start - Flutter

cd flutter_app
flutter pub get
flutter run

See flutter_app/README.md for detailed Flutter setup and usage instructions.

📱 React Frontend (Legacy)

A React TypeScript frontend for testing the Beauty LMS video conferencing system, including meeting management, real-time chat, and participant features.

Quick Start - React

npm install
npm start
