Technologies
Flutter, Firebase

1. Problem Statement & Requirements

Graduation projects involving mobile applications must demonstrate proper handling of real-time data sync, structured state management patterns, and system API integrations (such as Push Notifications and local storage caching).

  • Functional Requirements: Secure user Authentication, task creation & allocation, filters based on status metrics (To-Do, In-Progress, Done), and local reminder notification schedules.
  • Non-functional Requirements: Seamless native UI experience, local database cache support for offline availability, and automatic background sync.

2. Solution & System Architecture

The application is built on the **MVVM (Model-View-ViewModel)** architectural pattern to cleanly decouple data services from UI rendering, resulting in highly maintainable codebase:

MVVM Data Flow Diagram:

[UI View (Flutter Screen)] <--- (Notify / Listen) ---> [ViewModel (Provider / State)]
|
v (Call Repository)
[Firebase SDK / Cloud Firestore] <---> [Local SQFlite / Cache Store]

Implemented **Provider** state management to dynamically update task models in the view without rebuilding the entire UI tree, drastically reducing CPU/RAM usage and improving mobile battery life.

3. Technologies Used

Mobile Stack

Flutter SDK (Dart), Material Design 3 guidelines, Provider state library.

Backend Services

Firebase Auth, Cloud Firestore (Real-time DB), Firebase Cloud Messaging (FCM).

Local Storage

Shared Preferences (key-value config), SQFlite for offline data caching.

4. Results & Demo

Delivered fully optimized mobile layouts, ready to compiled into Android APK or iOS IPA installers for live simulator review by the thesis committee:

  • Instant real-time data synchronization with minimum latency utilizing active Firestore stream listeners.
  • Fully runnable on both mobile emulator environments and native smartphones.
  • Comes with clean codebase documentation including standard UML Class Diagrams.
