Describe the bug
When the RadialTrack has a end value smaller than 10, the range is not properly renderered and throws an exception
To Reproduce
`import 'package:flutter/material.dart';
import 'package:geekyants_flutter_gauges/geekyants_flutter_gauges.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({super.key});
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Flutter Demo',
home: const MyHomePage(title: 'Flutter Demo Home Page'),
);
}
}
class MyHomePage extends StatelessWidget {
const MyHomePage({super.key, required this.title});
final String title;
@override
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: RadialGauge(
track: RadialTrack(start: 0, end: 1),
needlePointer: [NeedlePointer(value: 0.1)],
),
),
);
}
}
`
Expected behavior
A gauge with a range from 0 to 1, with the needle at value 0.1. And no exception being thrown

This is a virus, at least according to my virusscanner
setting the steps to 1 seems to work :D
PR for the issue is here https://github.com/GeekyAnts/GaugesFlutter/pull/291
the PR still fixes it, but the it appears the number of steps is used as step size.
