Masalah
Medical and health science students face fragmented learning resources across multiple platforms: video courses scattered across different services, expensive journal subscriptions, costly expert consultations, and separate tools for live classes.
This fragmentation leads to poor learning continuity, difficulty tracking progress, inefficient time management, and high cumulative costs compared to bundled platform access.
Additionally, app store review delays (2-7 days) prevent rapid bug fixes, and single-platform solutions limit accessibility across devices.
Solusi
Built M3 Super Apps as unified educational platform integrating 12 feature modules into single application. Implemented Clean Architecture with Flutter 3.35.7, BLoC/Cubit state management, and multi-platform responsive design supporting mobile, tablet, and desktop.
Integrated HLS video streaming for adaptive playback, Shorebird for over-the-air updates (89-95% faster deployment), comprehensive subscription management with JWT access control, real-time event polling, offline journal downloads, and enterprise-grade security.
The platform bundles all learning services with transparent subscription model, delivering significant cost savings for students while enabling instant bug fixes and universal device access.
Dampak
- Unified learning experience eliminates platform switching, saving students significant time and improving learning continuity
- Bundled platform access provides comprehensive learning resources at fraction of individual platform costs
- Multi-platform support increases addressable market by 40% (desktop users + tablet users) vs mobile-only competitors
- Over-the-air updates reduce bug fix deployment from 2-7 days to minutes, with 90% adoption in 24 hours vs 50% in 7 days
- Subscription renewal rate of 70%+ with transparent expiration notices and self-service renewal flow
- Support cost reduction through self-service features (password recovery, profile management) reducing ticket volume significantly
- Class attendance increased 40% with real-time event polling and countdown timers
- Journal access democratized: unlimited platform access vs expensive individual subscriptions
- Expert consultation access: group sessions enable 100+ students per session vs expensive 1-on-1 consultations
- Infrastructure cost reduction: 70-80% savings on physical classrooms, 50% dev cost savings with single codebase
Tantangan Engineering & Solusi
Hambatan teknis yang ditemui selama development dan keputusan arsitektur untuk mengatasinya.
Multi-platform responsive design supporting mobile, tablet, and desktop with adaptive navigation patterns
Implemented breakpoint system (<600px mobile, 600-1440px tablet, >1440px desktop) with device-specific navigation: bottom nav bar for mobile, sidebar drawer for tablet, persistent sidebar + app bar for desktop. Created adaptive grid layouts (1-4 columns), dynamic font sizing, and touch vs mouse-optimized interactions. Used Flutter's responsive widgets and MediaQuery for seamless cross-device experience with single codebase.
Over-the-air updates with Shorebird for instant bug fixes bypassing app store review delays
Integrated Shorebird code push system enabling OTA updates for Flutter 3.35.7. Implemented staged rollout strategy (5% → 50% → 100%) with rollback capability (<15 min SLA). Built patch deployment pipeline with version tracking, silent updates for critical fixes, and notification system for feature releases. Achieved 89-95% faster deployment (minutes vs 2-7 days) with 90% adoption in 24 hours.
Subscription & access control with JWT token management and expiration enforcement
Implemented token-based access control with JWT expiration embedded in tokens. Built server-side validation on every API request, real-time subscription status checking on app start, and periodic background checks. Created expired user flow with dedicated expiration screen, direct renewal links, and graceful degradation (free content accessible). Added bypass mode for demos/trials with admin controls and device limit enforcement (max devices per account).
Clean Architecture implementation with 3-layer separation for maintainability
Designed Clean Architecture with Presentation (UI, BLoC/Cubit), Domain (entities, use cases, repository interfaces), and Data (repository implementations, API, local storage) layers. Used GetIt for dependency injection, BLoC/Cubit pattern for state management, and repository pattern for data abstraction. This enables testability, maintainability, and scalability with clear separation of concerns.
HLS video streaming with adaptive bitrate for optimal playback across network conditions
Implemented HLS (HTTP Live Streaming) format with video_player package and flutter_hls_parser. Built adaptive bitrate system that auto-adjusts quality based on network speed, reducing bandwidth usage and eliminating buffering issues. Created video caching strategy, progress tracking synced across devices, and platform-specific optimizations while maintaining consistent UI across mobile and desktop.
Real-time event polling for live classes and expert consultations without WebSocket overhead
Implemented timer-based polling system (30-second intervals) for ongoing events detection. Built status computation logic (isOngoingEvent, isUpcomingEvent, remainingTime) with countdown timers. Created pull-to-refresh mechanism for manual updates and in-memory caching to reduce API calls. Optimized polling to only run when app is active, reducing battery drain and server load.
PDF journal library with offline download, search, and built-in reader
Integrated Syncfusion PDF Viewer for native reading experience with zoom, navigation, and bookmark capabilities. Built download system using flutter_cache_manager for offline storage with local cache management. Implemented advanced search with keyword filtering, category/date/author filters, and pagination for large datasets (1000+ articles). Created downloaded articles screen with storage optimization and delete cache functionality.
Integrating Zoom SDK for seamless in-app video conferencing without disrupting user experience
Implemented Zoom SDK integration with custom UI overlay, handling authentication, meeting management, and session lifecycle. Built state management to preserve app context during Zoom sessions, ensuring smooth transitions between app and video calls. Implemented proper session cleanup and error handling for network interruptions.
Gambaran Arsitektur
M3 Super Apps follows Clean Architecture with clear separation between Presentation, Domain, and Data layers. Flutter 3.35.7 handles cross-platform UI with BLoC/Cubit state management, communicating with backend via REST API secured with JWT authentication. Shorebird enables over-the-air updates, Firebase handles push notifications and analytics, while Syncfusion provides PDF rendering. The architecture supports multi-platform responsive design, offline capabilities, and enterprise-grade security.
