TECHNICAL APPROACH

Frontend (App)Flutter (Dart)Cross-platform, low cost Android phones

DatabaseSQLite (Offline Storage)Firebase (Cloud Sync)

Backend (Future Scaling)FastAPI (Python)Dashboards & AI Model Integration

AI/MLPython (TensorFlow Lite)Adaptive Algorithms

Other LibrariesFlutter TTS (Text-to-Speech)Flutter i18n (Multi-language Support)

SYSTEM FLOW

1. Student logs in - select language and grade

2. Lessons/quizzes shown in local language with voice instructions

3. Progress stored in SQLite (offline) - syncs to Firebase when online

4. Adaptive difficulty: AI engine adjusts questions based on performance

5. Teacher/Parent dashboard (via backend/firebase) shows learning process
