## Overview

PlantCare AI is a Flask plant-care application with an Expo mobile shell that opens the hosted web app in a WebView. Users reach the Flask server, authenticate, submit plant images for diagnosis, and can use chat and review saved records. The sampled server excerpt shows diagnosis through Gemini and persistence through SQLite; the repository also contains a separate model-based prediction service and image-processing layer, but no sampled evidence connects that service to the Flask request flow. The tree lists page templates and model assets; their internal wiring is not shown.

Main entry points: [`PlantAppFlask/app.py`](https://github.com/kadamyogiraj/crop-disease-detection-app-/blob/main/PlantAppFlask/app.py) (Flask routes), [`PlantAppFlask/database.py`](https://github.com/kadamyogiraj/crop-disease-detection-app-/blob/main/PlantAppFlask/database.py) (SQLite records), [`PlantAppFlask/predict.py`](https://github.com/kadamyogiraj/crop-disease-detection-app-/blob/main/PlantAppFlask/predict.py) (Disease prediction), [`PlantAppMobile/App.js`](https://github.com/kadamyogiraj/crop-disease-detection-app-/blob/main/PlantAppMobile/App.js) (Mobile WebView)
