Safety Companion is a Flutter-based personal safety application built to provide fast emergency response tools, trusted-contact communication, and practical safety guidance in one mobile experience.
The app supports secure account access, one-tap emergency calling, live location sharing through SMS, nearby essential-service discovery, and curated safety-awareness content. It is organized with reusable UI modules and service-driven integrations so core safety actions remain quick, focused, and reliable during urgent situations.

Safety Companion follows a modular, UI-component-driven Flutter structure:
- Auth flow: authentication screens and auth-state based routing
- Screens layer: top-level containers like home and auth entry points
- Components layer: reusable UI widgets and feature sections
- Services layer: Firebase auth and Firestore interaction logic
- Utils layer: shared styling, constants, and helper widgets such as web view wrappers
This separation keeps feature UI, navigation, and backend integration relatively isolated, making the codebase easier to maintain and extend.
- Firebase auth-state stream based screen gating
- Service abstraction for auth and Firestore operations
- Reusable feature cards for emergency actions and nearby services
- Responsive widget layouts for narrow and wide mobile screens
- Validation for required registration inputs and emergency contact formatting
- Safety-first UX with quick access to call and location actions
- Consistent theme and color system through shared app color utilities
This project demonstrates practical Flutter app development for real-world safety use cases, including Firebase-backed authentication, Firestore user data integration, device capabilities (calling, location, SMS), modular UI composition, and user-centric emergency workflows.
