yashKappa/gym-management-system ? reverse-engineered prompt

Build me a gym management web app where the owner or admin can log in and manage the whole gym from one place.

I want the admin to be able to add and edit members, generate a unique code for each member, track receipts or payments, create diet plans and supplement plans, and send notifications to members. Members should be able to enter their unique code and see their own details, plans, and any updates meant for them.

Make it clean and easy to use, with a simple dashboard for the admin and a straightforward member view. Use the existing React and Firebase setup in the project, and make sure the data is saved properly so it works like a real management system. If you need to check current Firebase or React docs while building, go ahead and look them up online.
