radius property

String radius
final

Radius for placing the annotation. The value ranges from 0% to 100% and also if values are mentioned in pixel then the annotation will moved accordingly.

For example, if set 50% means the annotation starting text will be placed from the 50% chart area or we set 50 means the annotation starting text will be placed from 50 pixels.

Defaults to 0%.

Widget build(BuildContext context) {
   return Container(
       child: SfCircularChart(
           annotations: <CircularChartAnnotation>[
               CircularChartAnnotation(
                   radius: '10%'
                   widget: const Text('Circular'),
             ),
          ],
       )
   );
}
