getIntrinsicHeight method

@override int getIntrinsicHeight(int width)

Computes the intrinsic height of this widget under the given width constraint.

Important: When rendering layered widgets (like in SceneManager using LayerSizing.content), PromptRunner sets its backing buffer size based on the height returned by this method. It is highly recommended that custom widgets which act as root elements in layers override this to return their true height, otherwise the buffer may default to 1 line, causing drawing operations to clip or fail silently.

Implementation

@override
int getIntrinsicHeight(int width) {
  var maxH = 0;
  for (final child in children) {
    final h = child.getIntrinsicHeight(width);
    if (h > maxH) maxH = h;
  }
  return maxH;
}
