shilnisid/CangijooApp — reverse-engineered prompt

Build me a Flutter app called Cangijoo for managing inventory and simple CMS tasks. It should help a small business track products, raw materials, and suppliers in an easy mobile friendly interface.

Users should be able to sign up, log in, reset their password, and use Google login with Firebase. After logging in they should see a dashboard with inventory summaries and recent activity. They need screens to add, edit, delete, and monitor product stock, plus separate screens for raw material stock, purchases, and usage. There should also be a supplier database connected to products and materials.

Please include a clean modern UI with bottom navigation, a profile page, responsive layouts, and simple forms that are easy to understand. Add PDF or print report support for inventory reports. Use Firebase Auth and Firestore for the backend, and use GetX style state management and routing since this is a Flutter project. Look up current Flutter and Firebase docs online if you need to.
