ReactiveForm<T> class
This class is responsible for create a FormControlInheritedStreamer for
exposing a FormGroup to all descendants widgets.
It also configures the inner FormControlInheritedStreamer to rebuild
context each time the FormGroup.status changes.
The optional type argument T allows for specifying the type of result that
can be returned when a route associated with this form is popped.
