If all you need to do is compare the index to the currentIndex, you
don't need to define that index property. The ListView attaches a
boolean property to the instantiated delegate that indicates whether
the item is the current item. So you could get rid of that index
property by changing

 scale: (view.currentIndex == index) ? 1.2 : 1

to

 scale: ListView.isCurrentItem ? 1.2 : 1

Note that "ListView" isn't the id of the ListView element, but it's a
prefix for the name of the attached property. Here's a link to an
example in the official docs:
