<itemvalue="A [Shader] generated from a [FragmentProgram]. Instances of this class can be obtained from the [FragmentProgram.fragmentShader] method. The float uniforms list is initialized to the size expected by the shader and is zero-filled. Uniforms of float type can then be set by calling [setFloat]. Sampler uniforms are set by calling [setImageSampler]. A [FragmentShader] can be re-used, and this is an efficient way to avoid allocating and re-initializing the uniform buffer and samplers. However, if two [FragmentShader] objects with different float uniforms or samplers are required to exist simultaneously, they must be obtained from two different calls to [FragmentProgram.fragmentShader]."/>
<itemvalue="A shader (as used by [Paint.shader]) that tiles an image."/>
<itemvalue="For example, [ShaderMask] can be used to gradually fade out the edge of a child by using a [ui.Gradient.linear] mask."/>
<itemvalue="A widget that applies a mask generated by a [Shader] to its child."/>
<itemvalue="[Opacity], which can apply a uniform alpha effect to its child. [CustomPaint], which lets you draw directly on the canvas. [DecoratedBox], for another approach at decorating child widgets. [BackdropFilter], which applies an image filter to the background."/>
<itemvalue="custom paint"/>
<itemvalue="A filter operation to apply to a raster image. See also: [BackdropFilter], a widget that applies [ImageFilter] to its rendering. [ImageFiltered], a widget that applies [ImageFilter] to its children. [SceneBuilder.pushBackdropFilter], which is the low-level API for using this class as a backdrop filter. [SceneBuilder.pushImageFilter], which is the low-level API for using this class as a child layer filter."/>
<itemvalue="A description of a color filter to apply when drawing a shape or compositing a layer with a particular [Paint]. A color filter is a function that takes two colors, and outputs one color. When applied during compositing, it is independently applied to each pixel of the layer being drawn before the entire layer is merged with the destination. Instances of this class are used with [Paint.colorFilter] on [Paint] objects."/>
<itemvalue="Raw straight RGBA format. Unencoded bytes, in RGBA row-primary form with straight alpha, 8 bits per channel."/>
<itemvalue="Raw RGBA format. Unencoded bytes, in RGBA row-primary form with premultiplied alpha, 8 bits per channel."/>
<itemvalue="PNG format. A loss-less compression format for images. This format is well suited for images with hard edges, such as screenshots or sprites, and images with text. Transparency is supported. The PNG format supports images up to 2,147,483,647 pixels in either dimension, though in practice available memory provides a more immediate limitation on maximum image size."/>
<itemvalue="Registers this plugin as the default instance of VideoPlayerPlatform. Then your [VideoPlayer] will support all platforms. If registerWith is not called, the previous(usually official) implementation will be used when available."/>
<itemvalue="Creates an image from a list of bytes. This function attempts to interpret the given bytes an image. If successful, the returned [Future] resolves to the decoded image. Otherwise, the [Future] resolves to null. If the image is animated, this returns the first frame. Consider [instantiateImageCodec] if support for animated images is necessary. This function differs from [decodeImageFromList] in that it defers to [PaintingBinding.instantiateImageCodecWithSize], and therefore can be mocked in tests."/>
<itemvalue="Draws the subset of the given image described by the `src` argument into the canvas in the axis-aligned rectangle given by the `dst` argument. This might sample from outside the `src` rect by up to half the width of an applied filter. Multiple calls to this method with different arguments (from the same image) can be batched into a single call to [drawAtlas] to improve performance."/>
<itemvalue="A mask filter to apply to shapes as they are painted. A mask filter is a function that takes a bitmap of color pixels, and returns another bitmap of color pixels. Instances of this class are used with [Paint.maskFilter] on [Paint] objects."/>
<itemvalue="The shader to use when stroking or filling a shape. When this is null, the [color] is used instead. See also: [Gradient], a shader that paints a color gradient. [ImageShader], a shader that tiles an [Image]. [colorFilter], which overrides [shader]. [color], which is used if [shader] and [colorFilter] are null."/>
<itemvalue="Composes the `inner` filter with `outer`, to combine their effects. Creates a single [ImageFilter] that when applied, has the same effect as subsequently applying `inner` and `outer`, i.e., result = outer(inner(source))."/>
<itemvalue="[BackdropFilter], a widget that applies [ImageFilter] to its rendering. [ImageFiltered], a widget that applies [ImageFilter] to its children. [SceneBuilder.pushBackdropFilter], which is the low-level API for using this class as a backdrop filter. [SceneBuilder.pushImageFilter], which is the low-level API for using this class as a child layer filter."/>
<itemvalue="The time of the last change to the data or metadata of the file system object. On Windows platforms, this is instead the file creation time."/>
<itemvalue="Called when a pointer enters or exits the ink response area. The value passed to the callback is true if a pointer has entered this part of the material and false if a pointer has exited this part of the material."/>
<itemvalue="The color of the ink response when a pointer is hovering over it. If this property is null then the hover color of the theme, [ThemeData.hoverColor], will be used. See also: [highlightShape], the shape of the focus, hover, and pressed highlights. [highlightColor], the color of the pressed highlight. [focusColor], the color of the focus highlight. [splashColor], the color of the splash. [splashFactory], which defines the appearance of the splash."/>
<itemvalue="`alignment`: How the destination rectangle defined by applying `fit` is aligned within `rect`. For example, if `fit` is [BoxFit.contain] and `alignment` is [Alignment.bottomRight], the image will be as large as possible within `rect` and placed with its bottom right corner at the bottom right corner of `rect`. Defaults to [Alignment.center]."/>
<itemvalue="`fit`: How the image should be inscribed into `rect`. If null, the default behavior depends on `centerSlice`. If `centerSlice` is also null, the default behavior is [BoxFit.scaleDown]. If `centerSlice` is non-null, the default behavior is [BoxFit.fill]. See [BoxFit] for details."/>
<itemvalue="`rect`: The region of the canvas into which the image will be painted. The image might not fill the entire rectangle (e.g., depending on the `fit`). If `rect` is empty, nothing is painted."/>
<itemvalue="The arguments have the following meanings:"/>
<itemvalue="Paints an image into the given rectangle on the canvas."/>
