Implementation

Offset get center {
  var paintBounds = rect;
  SemanticsNode? current = this;
  while (current != null) {
    final transform = current.transform;
    if (transform != null) {
      paintBounds = MatrixUtils.transformRect(transform, paintBounds);
    }
    current = current.parent;
  }

  final devicePixelRatio =
      WidgetsBinding.instance.platformDispatcher.views.first.devicePixelRatio;
  return MatrixUtils.transformRect(
    Matrix4.diagonal3Values(
      1.0 / devicePixelRatio,
      1.0 / devicePixelRatio,
      1.0 / devicePixelRatio,
    ),
    paintBounds,
  ).center;
