intrinsicHeight property
If set to true, then this item's height will vary according to its
intrinsic height instead of using height property.
Note: If set to true and there isn't enough vertical room for the menu, there's
no way to know the item's intrinsic height in-advance to properly scroll to
the selected item. Instead, the provided height value will be used, which means
the menu's initial scroll offset may not properly scroll to the selected item.
Implementation
final bool intrinsicHeight;
