Additional features to the photo application admin panel made with Flutter

I want to control the user in my application from the admin panel of the photo application made with Flutter. When the user logs into the application, the admin panel will be warned. Let every photo that he takes be forwarded to the admin panel, let the cutting, cropping, brightness, contrast adjustment, photo background deletion (optional, this event will not happen if the user does not say delete the background of the photo) will be applied on this photo in the admin panel, and the template in the application will appear on the photo, then the person in the admin panel will do this. send the edited photo back to the user's device and print it
