      Make AppBar a Hero (#5214) · 628884a8
      Adam Barth authored
      This patch improves the Post and Shrine transitions by making the AppBar
      into a Hero and changing the default MaterialPageTransition. Now the
      AppBar transitions smoothly between screens and the
      MaterialPageTransition doesn't involve a fade effect.
      
      Also, rejigger the bounds of the image header in Pesto to avoid the
      "pop" at the end of the animation by laying out the image header at its
      final visual size instead of relying on occlusion to size the image
      header.
      
      Fixes #5202
      Fixes #5204

      Change how navigator prevents redundant operations (#4769) · 2af668f8
      Adam Barth authored
      * Change how navigator prevents redundant operations
      
      Instead of requiring transactions, we now cancel all active pointers that are
      interacting with the navigator and absorb future pointers until we get a chance
      to build. This approach isn't perfect (e.g., events that trigger off the
      cancelled pointers could still interact with the navigator), but it should be
      better than the current transaction-based approach.
      
      Fixes #4716
      
      * Remove openTransaction
      
      * test
      
      * fixup

      ImageIcon (#4649) · e502e9c8
      Ian Hickson authored
      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.

      Pesto: Fix app bar height when returning from recipe page. (#4579) · 02a44839
      Matt Perry authored
      The problem was that the Scaffold was getting a new key each time we
      navigated to the main page. The key influences where page state is
      stored, including the scroll offset. So for a single frame, the Scaffold
      incorrectly thinks the scroll offset is 0 and the app bar should be
      expanded.

      Refactor everything to do with images (#4583) · 2dfdc840
      Ian Hickson authored
      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). (see
        https://github.com/flutter/flutter/issues/4494)
