Each layer is supposed to reexport the parts of the previous layer
that are part of its API.
- In painting.dart, export from dart:ui all the Canvas-related APIs
that make sense to be used at higher levels, e.g. PaintingStyle.
- Delete painting/shadows.dart. It was dead code.
- In rendering/object.dart, export all of painting.dart.
- In widgets/basic.dart, export all of painting.dart and
animation.dart. Some classes in animation/ are renamed to make this
less disruptive and confusing to the namespace.
- Split out Stocks back into an import model rather than a part model,
so that it's easier to manage its dependencies on a per-file basis.
- Move Ticker to scheduler library.
- Remove as many redundant imports as possible now.
- Some minor nit picking cleanup in various files.
Introduces a new Tooltip class.
Adds support for tooltips to IconButton and Scaffold.
Adds some tooltips to various demos.
Also some tweaks to stack.dart that I made before I decided not to go
down a "CustomPositioned" route.
The TabBarSelection change animation needs to start where the fling's drag gesture ended rather than from zero. The intial vlaue of progress for the TabBarSelection's performance is now converted from the range used during an interactive drag, to the range used when animating from the previously selected tab to the new one.
TabBarSelection now requires a maxIndex parameter.
Users of MaterialApp can provide an onLocaleChanged handler that will be
called to asynchronously fetch locale-specific data. MaterialApp will
then instantiate a LocaleQuery that supplies the locale data to its
descendants.
Also:
- minor code reindents in places.
- reset the widget tree between tests.
- once you generate a route, don't let its builder change
(previously it would keep changing as the routes table changed).
- revert the stocks app toolbar-fading-on-forward-transition thing.
This patch restructures how we handle drawer. The drawer is now a child of the
Scaffold, which wraps the Drawer in a DrawerController. The DrawerController
manages the interaction with the navigator as well as the edge swiping. The
DrawerController's state machine is driven almost entirely off its Performance,
which it now owns completely.
Fixes#90Fixes#187Fixes#192Fixes#194Fixes#604
Heroes with the same tag have to have keys that are unique across the
entire subtree. Since we can now show both stock lists, this means we
have to include the tab in the heroes' keys.
Fixes#668.
The TabBar's selection is now represented by a TabBarSelection object which encapsulates both the previous and currently selected indices and the Performance used to animate the selection indicator.
Added a TabBarView class which displays a tab's contents. It uses a shared TabBarSelection to stay in sync with a TabBar. The TabBarView scrolls in sync with the TabBar when the selection changes. Eventually it will allow one to fling the selection forward or backwards.
Added a tabBar property to ToolBar. Typically the corresponding TabBarView will be the body of the toolbar's Scaffold.
Removed TabNavigatorView and TabNavigator.
Added a widget gallery tabs demo page. Removed the old tabs demo.
- `Scaffold.of(context).showBottomSheet(widget);`
- Returns an object with .closed Future and .close() method.
- Uses a StateRoute to handle back button.
- Take the Navigator logic out of the BottomSheet widget.
- Support showing a sheet while an old one is going away.
- Add Navigator.remove().
"showSnackBar()" is now a feature of a Scaffold. To get to a Scaffold
you either use a global key (`scaffoldKey.currentState.showSnackBar(...)`),
or you use `Scaffold.of(context)`.
Snack bars no longer have a route. They are entirely managed by the
Scaffold. Fixes#432.
Snack bars now queue up when you have several of them. Fixes#374.
Snack bars now auto-size themselves around their contents. This is step
one towards implementing multiline snack bars.
Snack bars now self-dismiss after some per-snackbar configurable period.
The self-dismissing pauses while a dialog is up above the snackbar (or
anything that uses ModalRoute). To enable this, there's now a
`ModalRoute.of(context)` API that returns the current ModalRoute, and
you will be rebuilt if you asked for this and the route's "current"
status changes. To implement this, the Navigator now rebuilds
unconditionally any time it pushes or pops a route.
Snack bars now use the curves that Android uses for snack bars.
Snack bar contents now fade in.
Shadows now render as three seprate MaskFilter.blur components per the most recent Material spec.
The shadows Map was replaced by a similar Map called elevationToShadow with entries that match the 10 elevations specifed by http://www.google.com/design/spec/what-is-material/elevation-shadows.html.
The "level" property (many classes) is now called "elevation", to match the Material spec.
BoxShadow now includes a spreadRadius parameter - as in CSS box-shadow. Renamed the BoxShadow blur property to blurRadius to further align BoxShadow with CSS box-shadow.
Factored OverlayRoute out of the modal and persistent bottom sheet clases, since the bottom sheet classes need to drive the performance.
Added a bottom sheet to the stocks demo: long-press on a stock shows a modal bottom sheet.
Made AnimatedModalBarrier public.
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.
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.
If you load the example and immediately switch to the Portfolio tab, you may
see exceptions due to symbols that are in the portfolio list but whose
data is not yet present in the stocks map
Make Radio widgets take a type that describes the type of their value,
so that you can catch when you use the wrong value.
Standardise on ValueChanged<Foo> instead of having a FooValueChanged
for every value of Foo.
Teach dumpRenderTree() to draw actual trees.
Make the TextStyle output terser so it doesn't overflow the output.
Make debugDumpApp() say what mode we're in (checked vs release).
Hide lifecycle state from release mode dumps (since it's checked-only state).
Add type annotations in many places.
Fix some identifiers to have more lint-satisfying names.
Make all operator==s consistent in style.
Reorder some functions for consistency.
Make ParentData no longer dynamic, and fix all the code around that.
