Overview
Presensi PKP is the official employee-attendance app for the Pangkalpinang city government, replacing manual fingerprint machines with GPS-verified mobile check-ins. Civil servants (ASN) clock in and out from the field, request leave, and review their attendance history — every action validated against the government's servers in real time.
Built in Flutter on a Clean Architecture + BLoC foundation, it ships to Android and iOS from a single codebase and today serves roughly 7,000 active employees at a 99.9% crash-free rate.

Key features
GPS-verified check-in
Clock in and out only within the office geofence, validated with geolocator over an OpenStreetMap view.
Fake-GPS detection
Mock-location and GPS-spoofing attempts are detected and blocked, so attendance can't be faked.
Photo capture
A camera capture at check-in adds a second layer of identity verification.
Leave requests (Izin)
Submit and track leave and permits with document attachments, end to end.
Attendance history
A calendar view of every past check-in, check-out, and daily status.
Push notifications
Firebase Cloud Messaging delivers reminders and real-time updates.
Server-time sync
Timestamps are locked to server time, not the device clock, to prevent tampering.
Offline-ready
Hive caching keeps the app responsive on unreliable field networks.
