    margin: EdgeInsets.only(left: 10, right: 10, top: 20),

        slider = value;
      });
    })

Use image to set slider

FutureBuilder(
  future: sliderFuture,
  builder: (BuildContext context, AsyncSnapshot<ui.Image> snapshot) {
    return DHSlider(
      value: slider,
      trackImage: snapshot.data,
      trackHeight: 13,

        color: Colors.red,
      ),
