wrong react native map boundaries when the map is rotated

Question

Summary

I'm using react-native-maps for the following issue.

I'm trying to get the visible map boundary using mapRef.current?.getMapBoundaries, it returns { northEast: LatLng, southWest: LatLng }, drawing a polyline of those coordinates is fine until you rotate the map, then it's going to give you wrong coordinates,

is there a better way to get visible map boundaries?

I used to get an output like { topLeft: LatLng, topRight: LatLng, bottomRight: LatLng, bottomLeft: LatLng } from other libraries,

is there a way to get four points like those that represent the map bounradaies.

Reproducible sample code

import { useCallback, useMemo, useRef, useState } from 'react';
import MapView, { BoundingBox, Polyline } from 'react-native-maps';

const initialRegion = {
  longitudeDelta: 0.15110325068235397,
  latitudeDelta: 0.1793406486560123,
  longitude: 55.26689613237977,
  latitude: 25.212185223887573,
};

export type ExampleProps = {
  //
};

export const Example: React.FC<ExampleProps> = () => {
  const mapRef = useRef<MapView>(null);

  const [mapBoundaries, setMapBoundaries] = useState<BoundingBox>();

  const handleRegionChangeComplete = useCallback(async () => {
    const mapBoundaries = await mapRef.current?.getMapBoundaries();

    if (!mapBoundaries) return;

    setMapBoundaries(mapBoundaries);
  }, []);

  const polylineCoordinates = useMemo(() => {
    if (!mapBoundaries) return [];

    return [mapBoundaries.northEast, mapBoundaries.southWest];
  }, [mapBoundaries]);

  return (
    <MapView
      ref={mapRef}
      initialRegion={initialRegion}
      onRegionChangeComplete={handleRegionChangeComplete}
    >
      <Polyline coordinates={polylineCoordinates} />
    </MapView>
  );
};

Steps to reproduce

• run the code.
• change the region (by moving in the map).
• a polyline, will be drawn from top right into bottom left.
• now try rotate the map and change the region.
• the polyline will not be drawn properly.

Expected result

the polyline should always be from top right into bottom left, or maybe the lib should give us 4 points instead of 2.

Actual result

the lib will not give me the right boundaries when rotation is applied.
