ViewLayoutStateGapBoxView implementations
do not use the maximum span of their children
the particular layout state may decide not to cache
the maximum span value and return preferred span instead
to save memory that would otherwise be used for caching variables.
If there is a dedicated variable for this value then
that variable gets updated by ViewLayoutState.updateLayout()
which usually happens once the view
has called View.preferenceChanged()
in the parent.
After the value gets updated the layout state must immediately call
Parent.minorAxisPreferenceChanged()
to notify the parent about the change of minor span.
