Delayno Driver

Completed

Dec 2025 - Jan 2026 (2 months)

Delayno Driver is a Flutter mobile application for delivery drivers, and this delivery window focused on stabilizing an already-shipped codebase rather than building new greenfield flows.

The work centered on location/map reliability, background trip update behavior, and release-hardening changes across iOS and Android so driver tracking and route visibility stayed predictable in production.

Built with: Flutter, Dart, Provider, bloc/flutter_bloc, Google Maps Flutter, geolocator/location, Firebase Core, Firebase Messaging, Flutter Local Notifications, Android Gradle/Kotlin, iOS native configuration, and FVM.

Recent updates for Delayno Driver. Completed

January 2026

  • Completed the location-update hardening pass by improving map startup responsiveness, adding a Germany fallback when current position is unavailable, and shipping iOS build 1.1.2+18 after map-flow fixes.
  • Standardized local Flutter toolchain management with FVM to keep debugging and release builds aligned across environments.
  • Continued Android-focused refactoring for trip location-update behavior to align map tracking reliability across platforms.
  • Delivered iOS release/branding updates (name normalization, icon refresh, TestFlight build 1.1.2+16) while removing Android flutter_background_geolocation usage and preparing the location-update refactor path.
  • Integrated background trip location updates (including flutter_background_geolocation adoption) and published iOS build 1.1.2+15 after validation.
  • Fixed background location-update regressions to restore consistent trip tracking and map continuity.
  • Addressed black-screen startup instability by patching map/scanner/history flow interactions and related service wiring.

December 2025

  • Mitigated a likely timer-driven black-screen path by adjusting app/map timing behavior during startup.
  • Implemented remember-me persistence (including credential clearing when disabled) and shipped urgent Android-side build/dependency updates to unblock high-priority bug fixes while iOS simulator constraints were present.
  • Applied a broad runtime-fix pass across map and supporting screens, plus iOS/build dependency updates, to stabilize driver flows in release testing.

Objective Link to heading

  • Stabilize an existing production Flutter driver app by fixing location/map reliability gaps and background trip-update behavior across iOS and Android.
  • Ship release-safe iterations by resolving startup/regression bugs, aligning platform-specific dependencies, and maintaining frequent TestFlight build progression.

Delivery scope Link to heading

  • Delivered map and location hardening by reducing delayed initial positioning, adding deterministic fallback coordinates, and improving location-update flow behavior.
  • Implemented and iterated background location update behavior, including plugin integration/removal adjustments and Android parity refactors.
  • Fixed black-screen and runtime regressions affecting startup/navigation confidence in production builds.
  • Maintained release cadence with multiple iOS build bumps and associated platform metadata/config updates.
  • Standardized local environment setup via FVM and synchronized Android/iOS dependency/build configuration as part of bug-fix delivery.

Technical foundation Link to heading

  • Flutter + Dart architecture with mixed provider and bloc/flutter_bloc state patterns.
  • Map and location stack built around Google Maps and device/background location services.
  • Firebase core + messaging integration with local-notification bridging for driver-facing delivery events.
  • Native platform wiring across Android Gradle and iOS Runner/Xcode settings, managed alongside FVM version pinning.
