SfRadialGauge class

Create a radial gauge widget to displays numerical values on a circular scale. It has a rich set of features such as axes, ranges, pointers, and annotations that are fully customizable and extendable. Use it to create speedometers, temperature monitors, dashboards, meter gauges, multi axis clocks, watches, activity gauges, compasses, and more.

The radial gauge widget allows customizing its appearance using SfGaugeThemeData available from the SfGaugeTheme widget or the SfTheme with the help of SfThemeData.

Widget build(BuildContext context) {
   return Container(
       child: SfRadialGauge());
}
