/// A widget library for Remote Flutter Widgets that defines widgets that are
/// implemented on the client in terms of Flutter widgets from the `widgets`
/// Dart library.
///
/// The following widgets are implemented:
///
/// * [Align]
/// * [AspectRatio]
/// * [Center]
/// * [ColoredBox]
/// * [Column]
/// * [Container] (actually uses [AnimatedContainer])
/// * [DefaultTextStyle]
/// * [Directionality]
/// * [Expanded]
/// * [FittedBox]
/// * [FractionallySizedBox]
/// * [GestureDetector]
/// * [GridView] (actually uses [GridView.builder])
/// * [Icon]
/// * [IconTheme]
/// * [IntrinsicHeight]
/// * [IntrinsicWidth]
/// * [Image] (see below)
/// * [ListBody]
/// * [ListView] (actually uses [ListView.builder])
/// * [Opacity] (actually uses [AnimatedOpacity])
/// * [Padding] (actually uses [AnimatedPadding])
/// * [Placeholder]
/// * [Positioned] (actually uses [AnimatedPositionedDirectional])
/// * [Rotation] (actually uses [AnimatedRotation])
/// * [Row]
/// * [SafeArea]
/// * [Scale] (actually uses [AnimatedScale])
/// * [SingleChildScrollView]
/// * [SizedBox]
/// * `SizedBoxExpand` (actually [SizedBox.expand])
/// * `SizedBoxShrink` (actually [SizedBox.shrink])
/// * [Spacer]
/// * [Stack]
/// * [Text]
/// * [Wrap]
///
/// For each, every parameter is implemented using the same name. Parameters
/// that take structured types are represented using maps, with each named
/// parameter of that type's default constructor represented by a key, with the
/// following notable caveats and exceptions:
///
/// * Enums are represented as strings with the unqualified name of the value.
/// For example, [MainAxisAlignment.start] is represented as the string
/// `"start"`.
///
/// * Types that have multiple subclasses (or multiple very unrelated
/// constructors, like [ColorFilter]) are represented as maps where the `type`
/// key specifies the type. Typically these have an extension mechanism.
///
/// * Matrices are represented as **column-major** flattened arrays. [Matrix4]
/// values must have exactly 16 doubles in the array.
///
/// * [AlignmentGeometry] values can be represented either as `{x: ..., y:
/// ...}` for a non-directional variant or `{start: ..., y: ...}` for a
/// directional variant.
///
/// * [BoxBorder] instances are defined as arrays of [BorderSide] maps. If the
/// array has length 1, then that value is used for all four sides. Two
/// values become the horizontal and vertical sides respectively. Three
/// values become the start, top-and-bottom, and end respectively. Four
/// values become the start, top, end, and bottom respectively.
///
/// * [BorderRadiusGeometry] values work similarly to [BoxBorder], as an array
/// of [Radius] values. If the array has one value, it's used for all corners.
/// With two values, the first becomes the `topStart` and `bottomStart`
/// corners and the second the `topEnd` and `bottomEnd`. With three, the
/// values are used for `topStart`, `topEnd`-and-`bottomEnd`, and
/// `bottomStart` respectively. Four values map to the `topStart`, `topEnd`,
/// `bottomStart`, and `bottomEnd` respectively.
///
/// * [Color] values are represented as integers. The hex literal values are
/// most convenient for this, the alpha, red, green, and blue channels map to
/// the 32 bit hex integer as 0xAARRGGBB.
///
/// * [ColorFilter] is represented as a map with a `type` key that matches the
/// constructor name (e.g. `linearToSrgbGamma`). The `matrix` version uses
/// the `matrix` key for the matrix, expecting a 20-value array. The `mode`
/// version expects a `color` key for the color (defaults to black) and a
/// `blendMode` key for the blend mode (defaults to [BlendMode.srcOver]).
/// Other types are looked up in [ArgumentDecoders.colorFilterDecoders].
///
/// * [Curve] values are represented as a string giving the kind of curve from
/// the predefined [Curves], e.g. `easeInOutCubicEmphasized`. More types may
/// be added using [ArgumentDecoders.curveDecoders].
///
/// * The types supported for [Decoration] are `box` for [BoxDecoration],
/// `flutterLogo` for [FlutterLogoDecoration], and `shape` for
/// [ShapeDecoration]. More types can be added with [decorationDecoders].
///
/// * [DecorationImage] expects a `source` key that gives either an absolute
/// URL (to use a [NetworkImage]) or the name of an asset in the client
/// binary (to use [AssetImage]). In the case of a URL, the `scale` key gives
/// the scale to pass to the [NetworkImage] constructor.
/// [DecorationImage.onError] is supported as an event handler with arguments
/// giving the stringified exception and stack trace. Values can be added to
/// [ArgumentDecoders.imageProviderDecoders] to override the behavior described here.
///
/// * [Duration] is represented by an integer giving milliseconds.
///
/// * [EdgeInsetsGeometry] values work like [BoxBorder], with each value in the
/// array being a double rather than a map.
///
/// * [FontFeature] values are a map with a `feature` key and a `value` key.
/// The `value` defaults to 1. (Technically the `feature` defaults to `NONE`,
/// too, but that's hardly useful.)
///
/// * The [dart:ui.Gradient] and [painting.Gradient] types are both represented
/// as a map with a type that is either `linear` (for [LinearGradient]),
/// `radial` (for [RadialGradient]), or `sweep` (for [SweepGradient]), using
/// the conventions from the [painting.Gradient] version. The `transform`
/// property on these objects is not currently supported. New gradient types
/// can be implemented using [ArgumentDecoders.gradientDecoders].
///
/// * The [GridDelegate] type is represented as a map with a `type` key that is
/// either `fixedCrossAxisCount` for
/// [SliverGridDelegateWithFixedCrossAxisCount] or `maxCrossAxisExtent` for
/// [SliverGridDelegateWithMaxCrossAxisExtent]. New delegate types can be
/// supported using [ArgumentDecoders.gridDelegateDecoders].
///
/// * [IconData] is represented as a map with an `icon` key giving the
/// [IconData.codePoint] (and corresponding keys for the other parameters of
/// the [IconData] constructor). To determine the values to use for icons in
/// the MaterialIcons font, see how the icons are defined in [Icons]. For
/// example, [Icons.flutter_dash] is `IconData(0xe2a0, fontFamily:
/// 'MaterialIcons')` so it would be represented here as `{ icon: 0xE2A0,
/// fontFamily: "MaterialIcons" }`. (The client must have the font as a
/// defined asset.)
///
/// * [Locale] values are defined as a string in the form `languageCode`,
/// `languageCode-countryCode`, or
/// `languageCode-scriptCode-countryCode-ignoredSubtags`. The string is split
/// on hyphens.
///
/// * [MaskFilter] is represented as a map with a `type` key that must be
/// `blur`; only [MaskFilter.blur] is supported. (The other keys must be
/// `style`, the [BlurStyle], and `sigma`.)
///
/// * [Offset]s are a map with an `x` key and a `y` key.
///
/// * [Paint] objects are represented as maps; each property of [Paint] is a
/// key as if there was a constructor that could set all of [Paint]'s
/// properties with named parameters. In principle all properties are
/// supported, though since [Paint] is only used as part of
/// [painting.TextStyle.background] and [painting.TextStyle.foreground], in
/// practice some of the properties are ignored since they would be no-ops
/// (e.g. `invertColors`).
///
/// * [Radius] is represented as a map with an `x` value and optionally a `y`
/// value; if the `y` value is absent, the `x` value is used for both.
///
/// * [Rect] values are represented as an array with four doubles, giving the
/// x, y, width, and height respectively.
///
/// * [ShapeBorder] values are represented as either maps with a `type` _or_ as
/// an array of [ShapeBorder] values. In the array case, the values are
/// reduced together using [ShapeBorder.+]. When represented as maps, the
/// type must be one of `box` ([BoxBorder]), `beveled`
/// ([BeveledRectangleBorder]), `circle` ([CircleBorder]), `continuous`
/// ([ContinuousRectangleBorder]), `rounded` ([RoundedRectangleBorder]), or
/// `stadium` ([StadiumBorder]). In the case of `box`, there must be a
/// `sides` key whose value is an array that is interpreted as per
/// [BoxBorder] above. Support for new types can be added using the
/// [ArgumentDecoders.shapeBorderDecoders] map.
///
/// * [Shader] values are a map with a `type` that is either `linear`,
/// `radial`, or `sweep`; in each case, the data is interpreted as per the
/// [Gradient] case above, except that the gradient is specifically applied
/// to a [Rect] given by the `rect` key and a [TextDirection] given by the
/// `textDirection` key. New shader types can be added using
/// [ArgumentDecoders.shaderDecoders].
///
/// * [TextDecoration] is represented either as an array of [TextDecoration]
/// values (combined via [TextDecoration.combine]) or a string which matches
/// the name of one of the [TextDecoration] constants (e.g. `underline`).
///
/// * [VisualDensity] is either represented as a string which matches one of the
/// predefined values (`adaptivePlatformDensity`, `comfortable`, etc), or as
/// a map with keys `horizontal` and `vertical` to define a custom density.
///
/// Some of the widgets have special considerations:
///
/// * [Image] does not support the builder callbacks or the [Image.opacity]
/// parameter (because builders are code and code can't be represented in RFW
/// arguments). The map should have a `source` key that is interpreted as
/// described above for [DecorationImage]. If the `source` is omitted, an
/// [AssetImage] with the name `error.png` is used instead (which will likely
/// fail unless such an asset is declared in the client).
///
/// * Parameters of type [ScrollController] and [ScrollPhysics] are not
/// supported, because they can't really be exposed to declarative code (they
/// expect to be configured using code that implements delegates or that
/// interacts with controllers).
///
/// * The [Text] widget's first argument, the string, is represented using the
/// key `text`, which must be either a string or an array of strings to be
/// concatenated.
///
/// One additional widget is defined, [AnimationDefaults]. It has a `duration`
/// argument and `curve` argument. It sets the default animation duration and
/// curve for widgets in the library that use the animated variants. If absent,
/// a default of 200ms and [Curves.fastOutSlowIn] is used.
LocalWidgetLibrary createCoreWidgets() => LocalWidgetLibrary(_coreWidgetsDefinitions);
// In these widgets we make an effort to expose every single argument available.
Map<String, LocalWidgetBuilder> get _coreWidgetsDefinitions => <String, LocalWidgetBuilder>{
// Keep these in alphabetical order and add any new widgets to the list
// in the documentation above.
