A biometric-authenticated medical logging application built with Flutter, Riverpod, and Supabase.

• Multi-role Support: Patient, Doctor, Pharmacist, and First Responder roles
• Biometric Authentication: Face ID / Fingerprint for secure, quick sign-in
• Prescription Management: Create, view, and dispense prescriptions
• Emergency QR Code: Scannable QR for first responders to access critical medical data
• Privacy Controls: Patients can mark data as public or private

• Flutter 3.7+ - Cross-platform framework
• Riverpod - State management
• Supabase - Backend (Auth, Database, Storage)
• local_auth - Biometric authentication
• go_router - Navigation

• Flutter SDK 3.7+
• A Supabase project

flutter pub get

1. Create a new project at supabase.com
2. Go to SQL Editor and run the contents of supabase/schema.sql
3. Copy your project URL and anon key

Edit lib/core/config/env_config.dart:

abstract class EnvConfig {
  static const String supabaseUrl = 'YOUR_SUPABASE_URL';
  static const String supabaseAnonKey = 'YOUR_SUPABASE_ANON_KEY';
}

Download the Outfit font family and place in assets/fonts/:

• Outfit-Regular.ttf
• Outfit-Medium.ttf
• Outfit-SemiBold.ttf
• Outfit-Bold.ttf

Or remove the fonts section from pubspec.yaml to use system fonts.

See supabase/schema.sql for the complete database schema including:

• profiles - User profiles with roles
• user_devices - Biometric device bindings
• patients - Patient-specific data
• doctors / pharmacists / first_responders - Role-specific data
• prescriptions - Medical prescriptions
• prescription_items - Individual medicines
• dispensing_records - Pharmacy transactions
• medical_conditions - Allergies, chronic conditions (for emergency access)

1. New User: Sign up with email → Biometric enrollment prompt → Device UUID generated and stored
2. Returning User (same device): Biometric verification → Instant sign-in
3. New Device: Email/password sign-in → Biometric enrollment for new device

Each device has its own biometric binding - biometric data never leaves the device.
