M Maintenance App
The M Maintenance App is a Flutter-based mobile application built to deliver a secure, stable, and responsive experience for field operations and maintenance management.
It ensures reliability by initializing essential background services—such as Firebase, Crashlytics, and push notifications—at startup, while maintaining smooth performance even under limited connectivity.
Overview
The M Maintenance App is a Flutter-based mobile application built to deliver a secure, stable, and responsive experience for field operations and maintenance management.
It ensures reliability by initializing essential background services—such as Firebase, Crashlytics, and push notifications—at startup, while maintaining smooth performance even under limited connectivity.
Key highlights include:
- Seamless offline support and session management
- Real-time push notification handling
- Background download management
- Fine-grained runtime permission control
- Integrated crash reporting and version validation
The app follows modern architectural best practices, emphasizing modular Firebase setup, clean navigation flow, and consistent UI/UX behavior across devices.
Problem Statement
Field and maintenance teams often face challenges with:
- Unstable Network Environments : Worksites may have intermittent or poor connectivity, causing web or API data to fail loading properly.
- Session & Authentication Issues : Without persistent session handling, users may experience frequent logouts or data revalidation errors.
- Lack of Background Sync : Critical updates (like version checks or push notifications) may not reach users when the app is minimized.
- Crash & Error Visibility : Runtime issues often go unnoticed, making debugging and support difficult.
- Slow App Startup : Default Flutter splash behavior causes a noticeable delay before UI initialization.
These factors collectively affected productivity, reliability, and user confidence in previous app versions.
Solution
The M Maintenance App addresses these issues through a structured, performance-first architecture:
- Unstable Connectivity : Implemented offline-friendly components and retry mechanisms using Dio and SharedPreferences for cached data.
- Session & Authentication : Centralized SessionManager handles secure, persistent storage of tokens and session IDs.
- Background Notifications : Integrated FirebaseMessaging.onBackgroundMessage() for handling push notifications even when the app is closed.
- Crash Reporting : Added firebase_crashlytics for real-time crash tracking and reporting.
- Slow Startup : Adopted flutter_native_splash to preload the native splash screen until Firebase and configurations finish loading.
- Permissions : Managed via permission_handler, requesting camera, microphone, and storage only when required.
- Navigation & Routing : Unified global navigation through MessagingService.navigatorKey to support deep links and FCM-based redirections.
This results in:
- Faster app initialization
- Fewer crashes and better diagnostics
- Continuous user session without disruption
- Smooth routing between splash, login, and dashboard views
- Consistent UX across Android and iOS
