<itemvalue="Whether the decoration is the same size as the input field. A collapsed decoration cannot have [labelText], [errorText], an [icon]. To create a collapsed input decoration, use [InputDecoration.collapsed]."/>
<itemvalue="Writes a string to a file. Opens the file, writes the string in the given encoding, and closes the file. Returns a `Future<File>` that completes with this [File] object once the entire operation has completed. By default [writeAsString] creates the file for writing and truncates the file if it already exists. In order to append the bytes to an existing file, pass [FileMode.append] as the optional mode parameter. If the argument [flush] is set to `true`, the data written will be flushed to the file system before the returned future completes."/>
<itemvalue="Window flag: hide all screen decorations (such as the status bar) while this window is displayed. This allows the window to use the entire display space for itself -- the status bar will be hidden when an app window with this flag set is on the top layer. A fullscreen window will ignore a value of SOFT_INPUT_ADJUST_RESIZE for the window's softInputMode field; the window will stay fullscreen and will not resize. This flag can be controlled in your theme through the android. R. attr. windowFullscreen attribute; this attribute is automatically set for you in the standard fullscreen themes such as android. R. style. Theme_NoTitleBar_Fullscreen, android. R. style. Theme_Black_NoTitleBar_Fullscreen, android. R. style. Theme_Light_NoTitleBar_Fullscreen, android. R. style. Theme_Holo_NoActionBar_Fullscreen, android. R. style. Theme_Holo_Light_NoActionBar_Fullscreen, android. R. style. Theme_DeviceDefault_NoActionBar_Fullscreen, and android. R. style. Theme_DeviceDefault_Light_NoActionBar_Fullscreen. Deprecated Use WindowInsetsController. hide(int) with WindowInsets. Type. statusBars() instead."/>
<itemvalue="Gets the headers associated with the request. These are represented as a mapping of header name to header value. Returns: the headers associated with the request."/>
<itemvalue="The default style configures the system bars with a transparent background when contrast can be enforced by the system (API 29 or above). On older platforms (which only have 3-button 2-button navigation modes), an equivalent scrim is applied to ensure contrast with the system bars."/>
<itemvalue="The sewage tank is currently empty, and there is sufficient clean water. Please confirm that the drainage pipe is in the lowered position before starting the self-cleaning of the sewage tank."/>
<itemvalue="Please confirm the drainage pipe is in the lowered position before starting self-cleaning."/>
<itemvalue="Return the presentation of this type as it should appear when presented to users in contexts such as error messages. If [withNullability] is `true`, then [NullabilitySuffix.question] and [NullabilitySuffix.star] will be represented as `?` and ``. [NullabilitySuffix.none] does not have any explicit presentation. If [withNullability] is `false`, nullability suffixes will not be included into the presentation. Clients should not depend on the content of the returned value as it will be changed if doing so would improve the UX."/>
<itemvalue="A [Reflector] implementation that performs no actual reflection, instead returning empty objects on every invocation. Use this in contexts where you know you won't need any reflective capabilities."/>
<itemvalue="A [Reflector] implementation that performs simple [Map] lookups. `package:angel_container_generator` uses this to create reflectors from analysis metadata."/>
<itemvalue="Adds a description of a specific type of widget missing from the current build context's ancestry tree. You can find an example of using this method in [debugCheckHasMaterial]."/>
<itemvalue="Returns the nearest widget of the given type `T` and creates a dependency on it, or null if no appropriate widget is found. The widget found will be a concrete [InheritedWidget] subclass, and calling [dependOnInheritedWidgetOfExactType] registers this build context with the returned widget. When that widget changes (or a new widget of that type is introduced, or the widget goes away), this build context is rebuilt so that it can obtain new values from that widget. {@template flutter.widgets.BuildContext.dependOnInheritedWidgetOfExactType} This is typically called implicitly from `of()` static methods, e.g. [Theme.of]."/>
<itemvalue="This callback shouldn't be used to update the slider [value] (use [onChanged] for that), but rather to be notified when the user has started selecting a new value by starting a drag or with a tap. The value passed will be the last [value] that the slider had before the change began."/>
<itemvalue="Called when the user starts selecting a new value for the slider."/>
<itemvalue="If [exclusive] is `true` and to-be-created file already exists, this operation completes the future with a [FileSystemException]. If [exclusive] is `false`, existing files are left untouched by [createSync]. Calling [createSync] on an existing file still might fail if there are restrictive permissions on the file."/>
<itemvalue="Creates an iOS 14 style selection overlay that highlights the magnified area (or the currently selected item, depending on how you described it elsewhere) of a [CupertinoPicker]. The [background] argument default value is [CupertinoColors.tertiarySystemFill]. It must be non-null. The [capStartEdge] and [capEndEdge] arguments decide whether to add a default margin and use rounded corners on the left and right side of the rectangular overlay. Default to true and must not be null."/>
<itemvalue="A delegate that supplies children for [ListWheelScrollView] using a builder callback. [ListWheelScrollView] lazily constructs its children to avoid creating more children than are visible through the [Viewport]. This delegate provides children using an [IndexedWidgetBuilder] callback, so that the children do not have to be built until they are displayed."/>
<itemvalue="list wheel child builder delegate"/>
<itemvalue="list wheel child looping list delegate"/>
<itemvalue="list wheel child list delegate"/>
<itemvalue="Constructs a list in which children are scrolled a wheel. Its children are managed by a delegate and are lazily built during layout."/>
<itemvalue="A box in which children on a wheel can be scrolled. This widget is similar to a [ListView] but with the restriction that all children must be the same size along the scrolling axis. {@youtube 560 315 https:www.youtube.comwatch?v=dUhmWAz4C7Y} When the list is at the zero scroll offset, the first child is aligned with the middle of the viewport. When the list is at the final scroll offset, the last child is aligned with the middle of the viewport. The children are rendered as if rotating on a wheel instead of scrolling on a plane."/>
<itemvalue="{@macro flutter.rendering.RenderListWheelViewport.squeeze} Defaults to `1.45` to visually mimic iOS."/>
<itemvalue="The uniform height of all children. All children will be given the [BoxConstraints] to match this exact height. Must not be null and must be positive."/>
