Example in pub.dev does not show minimal example

[guyluz11]

As you can se in the image the example page does not show any example

I would suggest something like this

SleekCircularSlider(
  onChangeStart: (double value) {},
  onChange: (value) {},
  onChangeEnd: (double value) {},
  appearance: CircularSliderAppearance(
    infoProperties: InfoProperties(modifier: (double value) {
      final budget = (value * 1000).toInt();
      return '\$ $budget';
    }),
  ),
),
