PointAnnotation
import { PointAnnotation } from '@rnmapbox/maps';
PointAnnotation
PointAnnotation represents a one-dimensional shape located at a single geographical coordinate.
Consider using ShapeSource and SymbolLayer instead, if you have many points and static images, they'll offer much better performance.
If you need interactive views please use MarkerView because PointAnnotation will render children onto a bitmap.
Also disable any kind of animations like fadeDuration of Image.
Otherwise, the bitmap might be rendered at an unknown state of the animation.
