getBounds method

@override GRect getBounds([ GRect? out ])

Returns the bounding box of the graphics object.

If out is provided, it sets the bounding box values to the given GRect and returns it. Otherwise, it creates a new GRect.

Implementation

@override
GRect getBounds([GRect? out]) {
  Rect? r;
  for (var e in _drawingQueue) {
    final pathRect = e?.path?.getBounds();
    if (pathRect == null) {
      break;
    }
    if (r == null) {
      r = pathRect;
    } else {
      r = r.expandToInclude(pathRect);
    }
  }
  final result = r ?? Rect.zero;
  if (out == null) {
    out = GRect.fromNative(result);
  } else {
    out.setTo(result.left, result.top, result.width, result.height);
  }
  return out;
}
