Tech Care System — Customer Mobile App

Mobile app runs three concurrent jobs: continuous vitals and location streaming from the Smart Stick, emergency dispatch with automatic ambulance contact, and a live incident view tracking Smart Stick, ambulance, and hospital on one map. All three must survive mobile network interruptions, OS background execution limits, and privacy constraints on health and location data.

Flutter app streaming Smart Stick telemetry via WebSocket. Interactive map renders live positions of device, ambulance, and hospital during incidents. FCM push notifications with deep links resume the incident screen on cold launch. Background isolate handles connectivity fallback. RBAC scopes data visibility by caregiver role.
