      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)

      Material Data Tables (#3337) · a91bc0ba
      Ian Hickson authored
      + Add new demo to gallery to show data tables. (This currently doesn't
      use a Card; I'll create a Card version in a subsequent patch.)
      
      + Fix checkbox alignment. It now centers in its box regardless.
      
      + Add Colors.black54.
      
      + Some minor fixes to dartdocs.
      
      + DataTable, DataColumn, DataRow, DataCell
      
      + RowInkWell
      
      + Augment dartdocs of materia/debug.dart.
      
      + DropDownButtonHideUnderline to hide the underline in a drop-down when
        used in a DataTable.
      
      + Add new capabilities to InkResponse to support RowInkWell.
      
      + Augment dartdocs of materia/material.dart.
      
      + Add an assert to catch nested Blocks.
      
      + Fix a crash in RenderBox when you remove an object and an ancestor
        used its baseline. (https://github.com/flutter/flutter/issues/2874)
      
      + Fix (and redocument) RenderBaseline/Baseline.
      
      + Add flex support to IntrinsicColumnWidth.
      
      + Document more stuff on the RenderTable side.
      
      + Fix a bug with parentData handling on RenderTable children.
      
      + Completely rewrite the column width computations. The old logic made
        no sense at all.
      
      + Add dartdocs to widgets/debug.dart.
      
      + Add a toString for TableRow.

      Table widget · baf06515
      Hixie authored
      - Add x and y to the parent data, in case it's useful. In point of fact,
        I ended up not needing it.
      
      - Make columnWidths settable rather than having a setter so that the
        code in the widgets layer is more idiomatic.
      
      - Teach setFlatChildren about avoiding unnecessary drop/adopt loops.
      
      - Assert that the child list length is correct more aggressively so that
        we catch the dumb bug I had more quickly next time.
      
      - Improve the toString() to handle empty tables better.
      
      - Resort the imports in framework.dart.
      
      - Introduce a LocalKey for cases where you don't want to allow use of
        GlobalKey.
      
      - Make inflateWidget and deactivateChild public for subclass use.
      
      - Table widget.
      
      - Cell widget.
      
      - TableRow fake widget.
