RadialSeekBar #

A RadialSeekBar is a draggable round progress bar.

The following sets up a StatefulWidget that implements dragging of a thumb.

class SimpleDraggingExample extends StatefulWidget {
  _SimpleDraggingExampleState createState() => _SimpleDraggingExampleState();

class _SimpleDraggingExampleState extends State<SimpleDraggingExample> {
  double _thumbPercent = 0.4;

  Widget build(BuildContext context) {
    // A RadialSeekBar is built in a 150x150 square, centered on screen.
    return Center(
      child: SizedBox(
        width: 150.0,
        height: 150.0,
        child: _buildRadialSeekBar(),

  Widget _buildRadialSeekBar() {
    return RadialSeekBar(
      trackColor: Colors.black,
      trackWidth: 4.0,
      progressColor: Colors.red,
      progressWidth: 8.0,
      progress: _thumbPercent,
      thumb: CircleThumb(
        color: Colors.red,
        diameter: 25.0,
      thumbPercent: _thumbPercent,
      onDragUpdate: (double percent) {
        setState(() {
          _thumbPercent = percent;

RadialProgressBar #

A RadialProgressBar is a progress bar that is shaped like a circle. RadialSeekBar is built atop a RadialProgressBar.

The following is a simple example of a RadialProgressBar:

  trackColor: Colors.black,
  trackWidth: 4.0,
  progressColor: Colors.red,
  progressWidth: 8.0,
  progress: 0.6,
