Why Android Camera Permission Stops Showing After First Denial — A Flutter Deep Dive

About a year ago at my previous company, I got a task from my boss that seemed straightforward at first. Our Flutter app had a structure where all permissions were requested at once during app initialization — handled inside a single service class that ran on startup. The request was simple: if a user denies camera permission at that point, make sure the permission popup shows up again when they navigate to a screen that actually needs the camera.
