ranjith4084/Geo_tag_camera — reverse-engineered prompt

Build me a Flutter package for a geo tagged camera that I can drop into another app.

I want it to open a clean camera screen, ask for camera and location permission, let the user take a photo, then save the photo with a watermark stamped on it. The watermark should include latitude and longitude, street address, date and time, and the compass direction the camera is facing. Please include camera basics like tap to focus, pinch to zoom, a rule of thirds grid, and simple device angle guidance.

Also add a nice settings screen where users can change the look of the watermark, switch light and dark style, choose aspect ratio, hide or show address and GPS, change date and time format, and optionally show a small map using OpenStreetMap or ESRI without needing an API key.

Make it work on Android and iOS, include the needed permission setup notes, and add a small example app that opens the camera and returns the saved image file.
