Computes the smallest bounding box that contains all points.

Throws if points is empty.

Implementation

static GoogleMapsUtilsLatLngBounds toBoundsFromPoints(
    List<Point<double>> points) {
  if (points.isEmpty) throw ArgumentError('Points cannot be empty');

  double x0 = points.first.x;
  double x1 = points.first.x;
  double y0 = points.first.y;
  double y1 = points.first.y;

  for (final point in points) {
    if (point.x > x1) x1 = point.x;
    if (point.x < x0) x0 = point.x;
    if (point.y > y1) y1 = point.y;
    if (point.y < y0) y0 = point.y;
  }

  return GoogleMapsUtilsLatLngBounds(
    northEast: Point<double>(x1, y1),
    southWest: Point<double>(x0, y0),
  );
}
