These now have sorter names to make the callers less verbose.

Some folks didn't realize these existed and asked us to add them. By using them in examples, hopefully folks will discover them more easily.

Anywhere that accepted IconData now accepts either an Icon or an ImageIcon. Places that used to take an IconData in an `icon` argument, notably IconButton and DrawerItem, now take a Widget in that slot. You can wrap the value that used to be passed in in an Icon constructor to get the same result. Icon itself now takes the icon as a positional argument, for brevity. ThemeData now has an iconTheme as well as a primaryIconTheme, the same way it has had a textTheme and primaryTextTheme for a while. IconTheme.of() always returns a value now (though that value itself may have nulls in it). It defaults to the ThemeData.iconTheme. IconThemeData.fallback() is a new method that returns an icon theme data structure with all fields filled in. IconTheme.merge() is a new constructor that takes a context and creates a widget that mixes in the new values with the inherited values. Most places that introduced an IconTheme widget now use IconTheme.merge. IconThemeData.merge and IconThemeData.copyWith act in a way analogous to the similarly-named members of TextStyle. ImageIcon is introduced. It acts like Icon but takes an ImageProvider instead of an IconData. Also: Fix the analyzer to actually check the stocks app.

Overview ======== This patch refactors images to achieve the following goals: * it allows references to unresolved assets to be passed around (previously, almost every layer of the system had to know about whether an image came from an asset bundle or the network or elsewhere, and had to manually interact with the image cache). * it allows decorations to use the same API for declaring images as the widget tree. It requires some minor changes to call sites that use images, as discussed below. Widgets ------- Change this: ```dart child: new AssetImage( name: 'my_asset.png', ... ) ``` ...to this: ```dart child: new Image( image: new AssetImage('my_asset.png'), ... ) ``` Decorations ----------- Change this: ```dart child: new DecoratedBox( decoration: new BoxDecoration( backgroundImage: new BackgroundImage( image: DefaultAssetBundle.of(context).loadImage('my_asset.png'), ... ), ... ), child: ... ) ``` ...to this: ```dart child: new DecoratedBox( decoration: new BoxDecoration( backgroundImage: new BackgroundImage( image: new AssetImage('my_asset.png'), ... ), ... ), child: ... ) ``` DETAILED CHANGE LOG =================== The following APIs have been replaced in this patch: * The `AssetImage` and `NetworkImage` widgets have been split in two, with identically-named `ImageProvider` subclasses providing the image-loading logic, and a single `Image` widget providing all the widget tree logic. * `ImageResource` is now `ImageStream`. Rather than configuring it with a `Future<ImageInfo>`, you complete it with an `ImageStreamCompleter`. * `ImageCache.load` and `ImageCache.loadProvider` are replaced by `ImageCache.putIfAbsent`. The following APIs have changed in this patch: * `ImageCache` works in terms of arbitrary keys and caches `ImageStreamCompleter` objects using those keys. With the new model, you should never need to interact with the cache directly. * `Decoration` can now be `const`. The state has moved to the `BoxPainter` class. Instead of a list of listeners, there's now just a single callback and a `dispose()` method on the painter. The callback is passed in to the `createBoxPainter()` method. When invoked, you should repaint the painter. The following new APIs are introduced: * `AssetBundle.loadStructuredData`. * `SynchronousFuture`, a variant of `Future` that calls the `then` callback synchronously. This enables the asynchronous and synchronous (in-the-cache) code paths to look identical yet for the latter to avoid returning to the event loop mid-paint. * `ExactAssetImage`, a variant of `AssetImage` that doesn't do anything clever. * `ImageConfiguration`, a class that describes parameters that configure the `AssetImage` resolver. The following APIs are entirely removed by this patch: * `AssetBundle.loadImage` is gone. Use an `AssetImage` instead. * `AssetVendor` is gone. `AssetImage` handles everything `AssetVendor` used to handle. * `RawImageResource` and `AsyncImage` are gone. The following code-level changes are performed: * `Image`, which replaces `AsyncImage`, `NetworkImage`, `AssetImage`, and `RawResourceImage`, lives in `image.dart`. * `DecoratedBox` and `Container` live in their own file now, `container.dart` (they reference `image.dart`). DIRECTIONS FOR FUTURE RESEARCH ============================== * The `ImageConfiguration` fields are mostly aspirational. Right now only `devicePixelRatio` and `bundle` are implemented. `locale` isn't even plumbed through, it will require work on the localisation logic. * We should go through and make `BoxDecoration`, `AssetImage`, and `NetworkImage` objects `const` where possible. * This patch makes supporting animated GIFs much easier. * This patch makes it possible to create an abstract concept of an "Icon" that could be either an image or a font-based glyph (using `IconData` or similar).

We now use the `@required` annotation to encourage developers to explicitly set onPressed and onChanged callbacks to null when that would disable the widget. Fixes #287
