What is the purpose of the optional `child` parameter available in `Consumer`'s builder function, e.g. `Consumer<CartModel>(builder: (context, cart, child) => ..., child: ExpensiveStaticWidget())`?
What is `Provider.value()` (as distinct from the standard `Provider(create: ...)`) used for, and why does its documentation warn against misusing it for object creation?
What does `ChangeNotifierProvider` do, and what is `ChangeNotifier` itself?
What is a `FutureProvider` used for in the Provider package?
What is `Selector<A, S>` used for in Provider, and how does it improve on plain `Consumer<A>` for optimizing rebuilds?
What is a potential downside of directly exposing a mutable `ChangeNotifier` object (as Provider commonly does) compared to BLoC's stricter event-in/state-out architecture?
What is Provider (the Flutter package)?
How does the Provider package relate to Flutter's official Riverpod package, given that both were created by the same author?
What happens if a widget calls `context.watch<T>()` (or `Provider.of<T>(context)` with default `listen: true`) for a type `T` that has NOT actually been provided anywhere higher up in the widget tree?
How does Provider's rebuild optimization work when a `ChangeNotifier`'s `notifyListeners()` is called -- does it rebuild the ENTIRE widget tree, or something more targeted?
Why might using `context.watch<T>()` directly inside a large widget's `build()` method (rather than wrapping just a small part of it in a `Consumer` or `Selector`) be a less optimal performance choice?
What is the purpose of `MultiProvider` in a Flutter app using the Provider package?
