What's the "UnsafeOptInUsageError"?

I'm using Google MLKit for barcode scanner. When I use imageProxy.image, IDE shows a warning;

" This declaration is opt-in and its usage should be marked with '@androidx.camera.core.ExperimentalGetImage' or '@OptIn(markerClass = androidx.camera.core.ExperimentalGetImage.class)'"

And it forces to use @SuppressLint("UnsafeOptInUsageError") annotation. I don't know what is it and couldn't find any resource(even official resource) about that. So why should this annotation be used?

This waring is from CameraX library rather ML Kit and you can suppress it by annotating the caller method with @ExperimentalGetImage like this.
