How to use ngAfterChanges in AngularDart

ngOnChanges is deprecated in favour of ngAfterChanges, but the former was given a list of properties that changed. The latter gets nothing. How do I know what changed so I can only perform expensive actions if a particular @Input changed?

Calculating the list of changes was actually expensive itself. So it was dropped instead I would suggest having a setter mark if something has changed for just the expensive inputs.
