ProgressBar class

A progress bar widget to show or set the location of the currently playing audio or video content.

This widget does not itself play audio or video content, but you can use it in conjunction with an audio plugin. It is a more convenient replacement for the Flutter Slider widget.

Constructors

ProgressBar({Key? key, required Duration progress, required Duration total, Duration? buffered, ValueChanged<Duration>? onSeek, ThumbDragStartCallback? onDragStart, ThumbDragUpdateCallback? onDragUpdate, VoidCallback? onDragEnd, double barHeight = 5.0, Color? baseBarColor, Color? progressBarColor, Color? bufferedBarColor, BarCapShape barCapShape = BarCapShape.round, double thumbRadius = 10.0, Color? thumbColor, Color? thumbGlowColor, double thumbGlowRadius = 30.0, bool thumbCanPaintOutsideBar = true, TimeLabelLocation? timeLabelLocation, TimeLabelType? timeLabelType, TextStyle? timeLabelTextStyle, double timeLabelPadding = 0.0})
You must set the current audio or video duration progress and also the total duration. Optionally set the buffered content progress as well.

inherited
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node.
override
didUnmountRenderObject(covariant RenderObject renderObject) → void
A render object previously associated with this widget has been removed from the tree. The given RenderObject will be of the same type as returned by this object's createRenderObject.
