I have a small Flutter productivity tool focused solely on task management. I need it compiled so that it installs and runs smoothly on Android 4.4.4 (KitKat). There is no user-authentication flow—just the core task-tracking screens—so the scope is limited to making the existing codebase compatible with that operating-system version. What you’ll do: • Resolve any Flutter or Gradle incompatibilities that prevent building for API 19. • Adjust dependencies or SDK settings as needed to target 32-bit devices. • Produce a signed, installable APK and a brief read-me describing the exact build steps I can replicate on my end. I will supply the current source code and keystore. Please test the final APK on an actual or emulated Android 4.4.4 device to confirm launch, navigation, and basic task-creation flow work without crashes.
