Widget build(BuildContext context) { final name = context.select((Person p) => p.name); return Text(name); } That is easy to understand. However, there are some examples of context.select() that I don't understand. For example, in the following code:class _AddButton extends StatelessWidget { final Item item; const _AddButton({Key key, @required this.item}) : super(key: key); @override Widget build(BuildContext context) { // The context.select() method will let you listen to changes to // a *part* of a model. You define a function that "selects" (i.e. returns) // the part you're interested in, and the provider package will not rebuild // this widget unless that particular part of the model changes. // // This can lead to significant performance improvements. var isInCart = context.select<CartModel, bool>( // Here, we are only interested whether [item] is inside the cart. (cart) => cart.items.contains(item), ); What change will cause the re-build of the above widget? How does the "provider" detect that change?
