<itemvalue="{@template dart.ui.textHeightBehavior} Defines how to apply [TextStyle.height] over and under text. [TextHeightBehavior.applyHeightToFirstAscent] and [TextHeightBehavior.applyHeightToLastDescent] represent whether the [TextStyle.height] modifier will be applied to the corresponding metric. By default both properties are true, and [TextStyle.height] is applied as normal. When set to false, the font's default ascent will be used.

<itemvalue="Whether the collection contains an element equal to [element]. This operation will check each element in order for being equal to [element], unless it has a more efficient way to find an element equal to [element]. The equality used to determine whether [element] is equal to an element of the iterable defaults to the [Object.==] of the element. Some types of iterable may have a different equality used for its elements. For example, a [Set] may have a custom equality (see [Set.identity]) that its `contains` uses. Likewise the `Iterable` returned by a [Map.keys] call should use the same equality that the `Map` uses for keys."/>
<itemvalue="The value for the given [key], or `null` if [key] is not in the map. Some maps allow `null` as a value. For those maps, a lookup using this operator cannot distinguish between a key not being in the map, and the key being there with a `null` value. Methods like [containsKey] or [putIfAbsent] can be used if the distinction is important."/>

<itemvalue="Runtime representation of a type. Type objects represent types. A type object can be created in several ways: By a type literal, a type name occurring as an expression, like `Type type = int;`, or a type variable occurring as an expression, like `Type type = T;`. By reading the run-time type of an object, like `Type type = o.runtimeType;`. Through `dart:mirrors`. A type object is intended as an entry point for using `dart:mirrors`. The only operations supported are comparing to other type objects for equality, and converting it to a string for debugging."/>
<itemvalue="ListFormat specifies the array format (a single parameter with multiple parameter or multiple parameters with the same name) and the separator for array items."/>
<itemvalue="Specifies the [SystemUiMode] to have visible when the application is running. The `overlays` argument is a list of [SystemUiOverlay] enum values denoting the overlays to show when configured with [SystemUiMode.manual]. If a particular mode is unsupported on the platform, enabling or disabling that mode will be ignored. The settings here can be overridden by the platform when System UI becomes necessary for functionality. For example, on Android, when the keyboard becomes visible, it will enable the navigation bar and status bar system UI overlays. When the keyboard is closed, Android will not restore the previous UI visibility settings, and the UI visibility cannot be changed until 1 second after the keyboard is closed to prevent malware locking users from navigation buttons. To regain "fullscreen" after text entry, the UI overlays can be set again after a delay of at least 1 second through [restoreSystemUIOverlays] or calling this again. Otherwise, the original UI overlay settings will be automatically restored only when the application loses and regains focus. Alternatively, a [SystemUiChangeCallback] can be provided to respond to changes in the System UI. This will be called, for example, when in [SystemUiMode.leanBack] and the user taps the screen to bring up the system overlays. The callback provides a boolean to represent if the application is currently in a fullscreen mode or not, so that the application can respond to these changes. When `systemOverlaysAreVisible` is true, the application is not fullscreen. See [SystemChrome.setSystemUIChangeCallback] to respond to these changes in a fullscreen application."/>
<itemvalue="Fullscreen display with status and navigation bars presentable by tapping anywhere on the display. Available starting at SDK 16 or Android J. Earlier versions of Android will not be affected by this setting. For applications running on iOS, the status bar and home indicator will be hidden for a similar fullscreen experience. Tapping on the screen displays overlays, this gesture is not received by the application. See also: [SystemUiChangeCallback], used to listen and respond to the change in system overlays."/>

<itemvalue="Handles errors emitted by this [Future]. This is the asynchronous equivalent of a "catch" block. Returns a new [Future] that will be completed with either the result of this future or the result of calling the `onError` callback. If this future completes with a value, the returned future completes with the same value. If this future completes with an error, then [test] is first called with the error value. If `test` returns false, the exception is not handled by this `catchError`, and the returned future completes with the same error and stack trace as this future. If `test` returns `true`, [onError] is called with the error and possibly stack trace, and the returned future is completed with the result of this call in exactly the same way as for [then]'s `onError`. If `test` is omitted, it defaults to a function that always returns true. The `test` function should not throw, but if it does, it is handled as if the `onError` function had thrown. Note that futures don't delay reporting of errors until listeners are added. If the first `catchError` (or `then`) call happens after this future has completed with an error then the error is reported as unhandled error. See the description on [Future]. Example: ```dart Future.delayed( const Duration(seconds: 1), () => throw 401, ).then((value) { throw 'Unreachable'; }).catchError((err) { print('Error: err'); Prints 401. }, test: (error) { return error is int && error >= 400; }); ``` The `Function` below stands for one of two types: - (dynamic) -> FutureOr<T> - (dynamic, StackTrace) -> FutureOr<T> Given that there is a `test` function that is usually used to do an `is` check, we should also expect functions that take a specific argument."/>
