For Developers

Built with 💜 using Flutter. Supports: Android - IOS - WEB

Learning these along the way:

State Management: For seamless data flow and app-wide state synchronization Provider (https://pub.dev/packages/provider) Flutter Bloc (https://pub.dev/packages/flutter_bloc) GetX (https://pub.dev/packages/get)

Firebase: For authentication, analytics, cloud fire-store, and cloud messaging functionalities

Serialization: JSON Serializable (https://pub.dev/packages/json_serializable)

Dependency Injection: GetIt (https://pub.dev/packages/get_it)

Data: Shared Preferences (https://pub.dev/packages/shared_preferences)

Repository: Dio (https://pub.dev/packages/http) Retrofit (https://pub.dev/packages/retrofit)

In addition, use-case specific dependencies such as firebase_core, fl_chart, synchronized, path_provider, intl, cached_network_image, url_launcher, carousel, and more. I have deliberately selected only the essential dependencies in this application to maintain a minimal app size.

Utilizing my familiarity/expertise in Android, it was easy to relate flutter concepts to their Android counterparts, making it a lot easier for me to grasp the new framework.
