EmergencyMesh — Offline P2P Emergency Broadcast App
Flutter Dart Nearby Connections Riverpod Firebase Dio Drift WebView
- Built an Android app to send SOS alerts over Bluetooth/Wi-Fi mesh, even without internet.
- Added multi-hop relay with Nearby Connections so alerts can travel across many phones.
- Captured GPS location automatically and kept the app running in the background during emergencies.
- Saved alerts locally with Drift and synced them to the cloud with Dio when internet was available.
- Used Riverpod for clean state management and Firebase for analytics.
