🚀 Tech Stack

• Flutter (Frontend UI)
• Firebase Auth & Firestore (User data)
• FastAPI (Backend)
• TensorFlow (Handwriting recognition)

✅ Prerequisites

Before running the app, ensure the following:

🔧 1. Backend Setup

• Set up the FastAPI backend and run the server at http://10.0.2.2:8000 (or use your actual backend IP/host).
• Backend must expose:
  • REST endpoints (BASE_URL)
  • WebSocket endpoints (WS_URL)
  • AI inference logic
  • Firebase Admin SDK access

🔥 2. Firebase Configuration

To set up Firebase for authentication and Firestore:

1. Install Firebase CLI:

   npm install -g firebase-tools

2. Log into Firebase:

   firebase login

3. Initialize Firebase:

   firebase init

This will generate:

firebase.json

google-services.json (for Android)

Update your Flutter project to use these files:

android/app/google-services.json

Ensure firebase_core and related packages are initialized.

⚙️ Setup Instructions

1. Clone this repository
2. Create a .env file in the root and define your backend URL:

   BASE_URL= https://your-server.com
   WS_URL = ws://your-server.com

3.Run the app:

 flutter pub get
 flutter run
