Centering node vertically in horizontal ASStackLayout

Question

I'm wonder what is the correct way to center textNode inside vertical ASSStackNode which is inside horizontal ASStackNode without setting any sizes?

I've tried different options with ASCenterLayout / ASRelativeLayout around vertical layout, flewGrow, flexShrink. Only possible way that I see is static layout with minimum height around vertical layout. But wanna find if there are another way.

If your ASTextNode is empty or nil. Isn't mean node not exist. If you want hide node if it empty, you must write a simple logic for it. For exlude it Spec from calculation. What i use on ADK1.9:

- (ASLayoutSpec *)layoutSpecThatFits: (ASSizeRange)constrainedSize
{
  NSMutableArray *arrayOfChildren = [NSMutableArray new];
  [arrayOfChildren insertObject:self.titleNode];
  if (self.textNode.text.length > 0) {
    [arrayOfChildren insertObject:self.textNode];
  }
  ASStackLayoutSpec *verticalElementCoreStack = [ASStackLayoutSpec stackLayoutSpecWithDirection:ASStackLayoutDirectionVertical spacing:8
                                                                                 justifyContent:ASStackLayoutJustifyContentCenter alignItems:ASStackLayoutAlignItemsStretch
                                                                                       children:arrayOfChildren];
  return verticalElementCoreStack;
}
