- 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.
