MapView.getPointInView returns array instead of GeoJSON Point

[brentforder]

Steps to Trigger Behavior

1. Get a reference to a MapView
2. Execute MapView.getPointInView() with a GeoJSON.Position parameter containing geographic coordinates
3. Check the output value with JSON.stringify or Array.isArray

Expected Behavior

Either:

• A) Output is a GeoJSON.Point, as per the getPointInView method signature
• B) The method signature is [number, number] or GeoJSON.Position

Actual Behavior

• Output is an array of view coordinates, in defiance of it's method signature

Environment

• Platform: Android
• OS version: Android 15
• Device type: Pixel 8
• Emulator or Simulator: no
• Development OS: Windows 11
• @maplibre/maplibre-react-native Version: 10.0.0-beta.19
• MapLibre Native Version: default
• react-native Version: 0.76.6
• expo Version: 52.0.25

Notes

I'm not sure yet if this is restricted to Android or due to a recent MLRN change.

In Typescript, a workaround is to cast the output of getPointInView to "unknown as [number, number]", i.e.

const mapViewPoint = mapViewReference.getPointInView(geographicCoordinates);
return mapViewPoint as unknown as [number, number];

... And then just treat it as [number, number] or GeoJSON.Position

GeoJSON implies geographic coordinates, so I think [number, number] makes more sense.
