hitTest method

@override Future<List<ArHitResult>> hitTest(double screenX, double screenY)

Perform a hit test at screen coordinates (normalized 0-1).

Implementation

@override
Future<List<ArHitResult>> hitTest(double screenX, double screenY) async {
  if (_controller == null) return [];

  final results = await _controller!.performHitTest(
    x: screenX,
    y: screenY,
  );

  return results.map((r) {
    ArHitType type;
    switch (r.type) {
      case ARKitHitTestResultType.existingPlaneUsingExtent:
      case ARKitHitTestResultType.existingPlaneUsingGeometry:
        type = ArHitType.existingPlane;
      case ARKitHitTestResultType.estimatedHorizontalPlane:
        type = ArHitType.estimatedPlane;
      case ARKitHitTestResultType.featurePoint:
        type = ArHitType.featurePoint;
      default:
        type = ArHitType.unknown;
    }

    return ArHitResult(
      type: type,
      distance: r.distance,
      pose: ArPose.fromMatrix4(r.worldTransform),
      anchorId: r.anchor?.identifier,
    );
  }).toList();
