This patch introduces the notion of a ModalRoute that puts up a modal barrier
and makes the route invisible to hit testing when its animating out. This patch
also uses this mechanism in a number of places (including PageRoute). There are
still a few more cases to convert, but that's work for a future patch.
Fixes#1684
We were trying to do a hero animation from a page to itself, which doesn't make
any sense. Now we only render the "to" page offstage if it is different from
the "from" page and if its performance isn't already complete.
This patch combines embedder.dart and shell.dart into one thing. We should now
handle a bunch of error cases better.
* embedder.connectToApplication has moved to shell.connectToApplication,
matching the rest of the mojo universe.
* embedder.connecttoService has moved to shell.connnectToService (and merged
with shell.requestService).
* shell.requestService is now shell.connectToService, matching the rest of
the mojo universe.
* serviceRegistry has moved from embedder.serviceRegistry to a top-level
getter.
Fixes#1803
Routes can now create a list of widgets, which can be empty (in the case of
contentless routes) or have multiple entries (in the case of modal routes).
Ephemeral routes are handled by keeping a separate list of modal and ephemeral
routes.
MixedViewport didn't use the building:true flag when locking itself, so
when it caused a rebuild of its children, we assumed that nobody was
allowed to mark things dirty below the list, and things crashed when
Inherited people did in fact rebuild.
Also:
- default offset for MixedViewport
- don't bother rebuilding if the underlying RenderObject is going to
rebuild anyway for some reason
- better docs for the "items must have keys" assert
- keep the FlipComponent stuff together in test_widgets.dart
Material design icons are defined to work at specific sizes: 18, 24, 36, 48.
The current API doesn't reflect that and just takes a size int. If an invalid
size is chosen an error is printed to the console and no icon shows up.
Fixes#1816
- 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.

We don't want to expose these from the gesture package. This patch moves
DoubleTapGestureRecognizer into tap.dart so we can make TapTracker and
TapGesture private to that file.
Instread of an explicit 'enabled' bool, this uses the presence of the
event handler to determine if a widget is enabled or not. This means
that if you've not passed a handler, your widget will be disabled, which
makes sense, since it wouldn't work anyway.
Adds this feature to checkbox, and ports raised button, flat button, and
radio buttons to this new model.
Adds a checkbox to card_collection that can be disabled.
Hide a (basically bogus) hint from the (soon to be disabled) strong hint
mode in the analyzer that this reveals.
We were assuming that the text extended from 0.0 to its max content width.
That's not correct for right-aligned text. Instead, we need to layout the text
again at the width we want it to occupy.
