## Overview

This is a Flutter cross-platform eRelax app whose visible product areas cover service discovery, therapist appointment booking, sign-up/login, and administration. The likely user journey is browsing services, selecting a therapist, date and time, then booking; the tree also identifies a booking store and reusable navigation/UI layers. The README is generic and the Dart implementation was not sampled, so screen-to-screen calls and persistence behavior cannot be verified. Native runner components are included because the source index marks them as core modules.
