- Change RouteArguments to pass the route's BuildContext rather than
the Navigator. This caused the bulk of the examples/ and .../test/
changes (those are mostly mechanical changes). It also meant I could
simplify Navigator.of().
- Make initState() actually get called when the State's Element is in
the tree, so you can use Foo.of() functions there. Added a test for
this also.
- Provide a RouteWidget so that routes have a position in the Widget
tree. The bulk of the route logic is still in a longer-lived Route
object for now.
- Make Route.setState() only rebuild the actual route, not the whole
navigator.
- Provided a Route.of().
- Provided a Route.writeState / Route.readState API that tries to
identify the clients by their runtimeType, their key, and their
ancestors keys, up to the nearest ancestor with a GlobalKey.
- Made scrollables hook into this API to track state. Added a test to
make sure this works.
- Fix the debug output of GestureDetector and the hashCode of
MixedViewport.
- Fixed ScrollableWidgetListState<T> to handle infinite lists.
Previous these callbacks were leaking the implementation detail that they were
triggered by taps. In a later patch, we're going to add a parameter to
GestureTapCallback that these callbacks won't have.

(These are changes cherry-picked from in-flight branches since they are
more independent and could be helpful even without those changes.)
- Change RouteBuilder's signature to take a single argument in which the
other fields are placed, so that we can keep iterating on those
arguments without having to break compatibility each time. Also, this
makes defining route builders much simpler (only one argument to
ignore rather than a variable number).
- Expose the next performance to RouteBuilders, since sometimes the
route itself might not be where it's used.
- Allow BuildContext to be used to walk children, just like it can for
ancestors
- Allow BuildContext to be used to get the Widget of the current
BuildContext
- Allow StatefulComponentElement to be referenced with a type
specialisation so that you don't have to cast when you know what the
type you're dealing with actually is.
