## Overview

This is a Tangail district information and services portal: residents browse local services, filter directories, open detail pages, and use contact links; administrators maintain the directory. The README documents a Flutter mobile app, but the supplied tree exposes only its Android launch shell, so its internal workflow cannot be mapped. Web page excerpts show client-side filtering and homepage navigation, while most data-fetch and persistence code was not sampled; Firebase relationships are therefore documented rather than traced through callers.

Main entry points: [`web/src/app/page.tsx`](https://github.com/monirul1128/tangail-app/blob/main/web/src/app/page.tsx) (Home page), [`web/src/app/hospitals/HospitalsClient.tsx`](https://github.com/monirul1128/tangail-app/blob/main/web/src/app/hospitals/HospitalsClient.tsx) (Hospital directory), [`web/src/app/doctors/DoctorsClient.tsx`](https://github.com/monirul1128/tangail-app/blob/main/web/src/app/doctors/DoctorsClient.tsx) (Doctor directory), [`web/src/app/ambulance/AmbulanceClient.tsx`](https://github.com/monirul1128/tangail-app/blob/main/web/src/app/ambulance/AmbulanceClient.tsx) (Ambulance directory)
