CoCo Mobile App
Overview
CoCo is a cross-platform mobile application built with Flutter that combines task management with media capture capabilities. It uses Firebase for authentication and cloud data storage, and follows a clean architecture with BLoC pattern for state management.
Features
- Firebase Authentication — User registration and login with secure session handling
- Firestore task management — Create, read, update, and delete tasks synced in real-time across devices
- Camera & media — Capture photos and pick images from gallery using native device APIs
- BLoC state management — Predictable, testable state transitions with flutter_bloc and Cubit
- Cross-platform — Runs on Android, iOS, web, Windows, macOS, and Linux from a single codebase
- Custom typography — WixMadeforText font family with full weight and italic variants
- Charts & visualization — Data visualization with fl_chart
Technical Highlights
The app follows a layered architecture: screens for UI, blocs for business logic, services for Firebase interactions, and reusable widgets. Authentication is managed through a dedicated AuthCubit that handles login, signup, and session lifecycle. Firestore security rules enforce per-user document access so users can only read and modify their own data.
Media interactions are handled through a separate module that abstracts camera access and image picking, supporting both the native camera and gallery on mobile platforms.
What I Learned
This was a collaborative project built with a teammate, which gave me experience with Git-based team workflows including pull requests and code reviews. Working with Firebase taught me about NoSQL data modeling, security rules, and real-time synchronization. Implementing BLoC pattern solidified my understanding of reactive state management and separation of concerns in mobile apps.
