A simple MobX/Provider convience widget.
There are 6 generic variants of Observing so that it's compatible with
Provider's Consumer. Any type may be used, not just mobx stores, as
long as they're provided as an ancestor to the Observing widget of course.
In fact it works with ChangeNotifierProvider as well for some real reactive
programming fun.
Provider(
create: (context) => ViewModel(),
child: Observing<ViewModel>(
builder: (context, viewModel) => GestureDetector(
onTap: viewModel.increment,
child: Text(
viewModel.value.toString(),
key: key,
textDirection: TextDirection.ltr,
),
),
),
);
