    1. Provider even includes its own BuildContext sub class, which is why we can work with Provider so seamlessly in the widget tree

      (As a Flutter noob,) I don't follow this implication. Why does having a BuildContext subclass mean that Provider behaves seamlessly in a widget tree? It would be able to extract data from BuildContext parameters passed to it, and pass that information to widgets nested in it without having a customized BuildContext subclass, wouldn't it (or is this besides the point)?
