@override
Widget build(BuildContext context) {
const segments = <GaugeSegment>[
GaugeSegment(from: 0, to: 20.0, color: Colors.transparent, cornerRadius: Radius.circular(10)),
GaugeSegment(from: 20.0, to: 40.0, color: Colors.transparent, cornerRadius: Radius.circular(10)),
GaugeSegment(from: 40.0, to: 60, color: Colors.transparent, cornerRadius: Radius.circular(10)),
GaugeSegment(from: 60.0, to: 80, color: Colors.transparent, cornerRadius: Radius.circular(10)),
GaugeSegment(from: 80.0, to: 100, color: Colors.transparent, cornerRadius: Radius.circular(10)),
