RadialAxis class Null safety

The RadialAxis is a circular arc in which a set of values are displayed along a linear or custom scale based on the design requirements.

Widget build(BuildContext context) {
   return Container(
       child: SfRadialGauge(
         axes:<RadialAxis>[RadialAxis(
           )]
       ));
}
