Methods
-
animate(
{Key? key, List< Effect> ? effects, AnimateCallback? onInit, AnimateCallback? onPlay, AnimateCallback? onComplete, bool? autoPlay, Duration? delay, AnimationController? controller, Adapter? adapter, double? target, double? value}) → Animate -
Available on Widget, provided by the AnimateWidgetExtensions extension
Wraps the target Widget in an Animate instance, and returns the instance for chaining calls. Ex.myWidget.animate()is equivalent toAnimate(child: myWidget). -

inherited
-
createState(
) → State< ProgressBar> -
Creates the mutable state for this widget at a given location in the tree.
override
-
debugDescribeChildren(
) → List< DiagnosticsNode> -
Returns a list of DiagnosticsNode objects describing this node's
children.
inherited
-
debugFillProperties(
DiagnosticPropertiesBuilder properties) → void -
