<itemvalue="Cancels this subscription. After this call, the subscription no longer receives events. The stream may need to shut down the source of events and clean up after the subscription is canceled. Returns a future that is completed once the stream has finished its cleanup. Typically, cleanup happens when the stream needs to release resources. For example, a stream might need to close an open file (as an asynchronous operation). If the listener wants to delete the file after having canceled the subscription, it must wait for the cleanup future to complete. If the cleanup throws, which it really shouldn't, the returned future completes with that error."/>
<itemvalue="The following defines the version and build number for your application. A version number is three numbers separated by dots, like 1.2.43 followed by an optional build number separated by a +. Both the version and the builder number may be overridden in flutter build by specifying --build-name and --build-number, respectively. In Android, build-name is used as versionName while build-number used as versionCode. Read more about Android versioning at https:developer.android.comstudiopublishversioning In iOS, build-name is used as CFBundleShortVersionString while build-number is used as CFBundleVersion. Read more about iOS versioning at https:developer.apple.comlibraryarchivedocumentationGeneralReferenceInfoPlistKeyReferenceArticlesCoreFoundationKeys.html In Windows, build-name is used as the major, minor, and patch parts of the product and file versions while build-number is used as the build suffix."/>
<itemvalue="Fixes the [SnackBar] at the bottom of the [Scaffold]. The exception is that the [SnackBar] will be shown above a [BottomNavigationBar] or a [NavigationBar]. Additionally, the [SnackBar] will cause other non-fixed widgets inside [Scaffold] to be pushed above (for example, the [FloatingActionButton])."/>
<itemvalue="The currently selected value for a group of radio buttons. This radio button is considered selected if its [value] matches the [groupValue]."/>
<itemvalue="A decimal-point string-representation of this number. Converts this number to a [double] before computing the string representation, as by [toDouble]. If the absolute value of `this` is greater than or equal to `10^21`, then this methods returns an exponential representation computed by `this.toStringAsExponential()`. Otherwise the result is the closest string representation with exactly [fractionDigits] digits after the decimal point. If [fractionDigits] equals 0, then the decimal point is omitted. The parameter [fractionDigits] must be an integer satisfying: `0 <= fractionDigits <= 20`."/>
<itemvalue="If `dart:ui` passes an `Image` object and the recipient wishes to share that handle with other callers, [clone] must be called _before_ [dispose]. A handle that has been disposed cannot create new handles anymore."/>
<itemvalue="A class or method that receives an image object must call [dispose] on the handle when it is no longer needed. To create a shareable reference to the underlying image, call [clone]. The method or object that receives the new instance will then be responsible for disposing it, and the underlying image itself will be disposed when all outstanding handles are disposed."/>
<itemvalue="Opaque handle to raw decoded image data (pixels). To obtain an [Image] object, use the [ImageDescriptor] API. To draw an [Image], use one of the methods on the [Canvas] class, such as [Canvas.drawImage]."/>
<itemvalue="All the arguments are required and must not be null, except for [filterQuality]. If [filterQuality] is not specified at construction time it will be deduced from the environment where it is used, such as from [Paint.filterQuality]."/>
<itemvalue="The fourth argument gives the matrix to apply to the effect. The expression `Matrix4.identity().storage` creates a [Float64List] prepopulated with the identity matrix."/>
<itemvalue="The second and third arguments specify the [TileMode] for the x direction and y direction respectively. [TileMode.repeated] can be used for tiling images."/>
<itemvalue="Creates an image-tiling shader. The first argument specifies the image to render. The [decodeImageFromList] function can be used to decode an image from bytes into the form expected here. (In production code, starting from [instantiateImageCodec] may be preferable.)"/>

<itemvalue="On success, [rayNear] and [rayFar] are the points where the screen space [pickX], [pickY] intersect with the near and far planes respectively. The viewport is specified by ([viewportX], [viewportWidth]) and ([viewportY], [viewportHeight]). [cameraMatrix] includes both the projection and view transforms.

<itemvalue="The `blendMode` parameter is used to control how the colors in the `vertices` are combined with the colors in the `paint`. If there are no colors specified in `vertices` then the `blendMode` has no effect. If there are colors in the `vertices`, then the color taken from the [Paint.shader] or [Paint.color] in the `paint` is blended with the colors specified in the `vertices` using the `blendMode` parameter. For the purposes of this blending, the colors from the `paint` parameter are considered the source, and the colors from the `vertices` are considered the destination. [BlendMode.dst] ignores the `paint` and uses only the colors of the `vertices`; [BlendMode.src] ignores the colors of the `vertices` and uses only the colors in the `paint`."/>
<itemvalue="If the `indices` parameter is specified, all values in the list must be valid index values for pairs in `positions`. For example, if there are 12 numbers in `positions` (representing 6 coordinates), the `indicies` must be numbers in the range 0..5 inclusive. The `mode` and `positions` parameters must not be null."/>
<itemvalue="The `positions` parameter provides the points in the canvas space that will be use to draw the triangles. Each point is represented as two numbers in the list, the first giving the x coordinate and the second giving the y coordinate. (As a result, the list must have an even number of entries.)"/>
<itemvalue="Creates a set of vertex data for use with [Canvas.drawVertices], using the encoding expected by the Flutter engine. The `mode` parameter describes how the points should be interpreted: as independent triangles ([VertexMode.triangles]), as a sliding window of points forming a chain of triangles each sharing one side with the next ([VertexMode.triangleStrip]), or as a fan of triangles with a single shared point ([VertexMode.triangleFan])."/>
