heightOf method

Implementation

double heightOf(RenderObject? node) {
  double? height;
  while (true) {
    if (node == null) break;
    if (node is RenderBox && node.constraints.hasBoundedHeight) {
      height = node.constraints.maxHeight;
      break;
    }
    node = node.parent;
  }
  return height ?? System().screenheight.toDouble();
}
