<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. [TextHeightBehavior.leadingDistribution] determines how the leading is distributed over and under text. This property applies before [TextHeightBehavior.applyHeightToFirstAscent] and [TextHeightBehavior.applyHeightToLastDescent]. {@endtemplate}"/>

<itemvalue="Spacer creates an adjustable, empty spacer that can be used to tune the spacing between widgets in a [Flex] container, like [Row] or [Column]. The [Spacer] widget will take up any available space, so setting the [Flex.mainAxisAlignment] on a flex container that contains a [Spacer] to [MainAxisAlignment.spaceAround], [MainAxisAlignment.spaceBetween], or [MainAxisAlignment.spaceEvenly] will not have any visible effect: the [Spacer] has taken up all of the additional space, therefore there is none left to redistribute."/>

<itemvalue="A widget that controls how a child of a [Row], [Column], or [Flex] flexes. Using a [Flexible] widget gives a child of a [Row], [Column], or [Flex] the flexibility to expand to fill the available space in the main axis (e.g., horizontally for a [Row] or vertically for a [Column]), but, unlike [Expanded], [Flexible] does not require the child to fill the available space. A [Flexible] widget must be a descendant of a [Row], [Column], or [Flex], and the path from the [Flexible] widget to its enclosing [Row], [Column], or [Flex] must contain only [StatelessWidget]s or [StatefulWidget]s (not other kinds of widgets, like [RenderObjectWidget]s)."/>
