## Overview

This appears to be a Flutter app for Posyandu child-growth monitoring, with role-specific home screens and features for child records, examinations, education, schedules, consultations, reports, and administration. The principal health workflow is entering an examination and classifying measurements; a sampled Firestore trigger calculates status and writes it back. Sampled backend code also sends announcements, education, and schedule notifications. The README is only Flutter boilerplate, and Flutter screen implementations were not sampled, so their internal navigation and Firebase wiring are uncertain and omitted.

Main entry points: [`functions/stunting_calc.py`](https://github.com/tamafawx/stunting-check-app/blob/main/functions/stunting_calc.py) (Growth classification), [`functions/notifikasi_edukasi.py`](https://github.com/tamafawx/stunting-check-app/blob/main/functions/notifikasi_edukasi.py) (Education notifier), [`functions/notifikasi_jadwal.py`](https://github.com/tamafawx/stunting-check-app/blob/main/functions/notifikasi_jadwal.py) (Schedule notifier), [`functions/notifikasi_pengumuman.py`](https://github.com/tamafawx/stunting-check-app/blob/main/functions/notifikasi_pengumuman.py) (Announcement notifier)
