<itemvalue="A Material Design linear progress indicator, also known as a progress bar. {@youtube 560 315 https:www.youtube.comwatch?v=O-rhXZLtpv0} A widget that shows progress along a line. There are two kinds of linear progress indicators: _Determinate_. Determinate progress indicators have a specific value at each point in time, and the value should increase monotonically from 0.0 to 1.0, at which time the indicator is complete. To create a determinate progress indicator, use a non-null [value] between 0.0 and 1.0. _Indeterminate_. Indeterminate progress indicators do not have a specific value at each point in time and instead indicate that progress is being made without indicating how much progress remains. To create an indeterminate progress indicator, use a null [value]. The indicator line is displayed with [valueColor], an animated value. To specify a constant color value use: `AlwaysStoppedAnimation<Color>(color)`. The minimum height of the indicator can be specified using [minHeight]. The indicator can be made taller by wrapping the widget with a [SizedBox]. {@tool dartpad} This example shows a [LinearProgressIndicator] with a changing value. See code in examplesapilibmaterialprogress_indicatorlinear_progress_indicator.0.dart {@end-tool} See also: [CircularProgressIndicator], which shows progress along a circular arc. [RefreshIndicator], which automatically displays a [CircularProgressIndicator] when the underlying vertical scrollable is overscrolled. <https:material.iodesigncomponentsprogress-indicators.htmllinear-progress-indicators>"/>
<itemvalue="The handler for [SemanticsAction.tap]. This is the semantic equivalent of a user briefly tapping the screen with the finger without moving it. For example, a button should implement this action. VoiceOver users on iOS and TalkBack users on Android can trigger this action by double-tapping the screen while an element is focused."/>
