How to use leaf slider with markercluster in javascript?

Question

I am creating a map that uses a slider to show or hide markers, and I want to add clustering functionality, each of them works fine, but I want the slider to show markers, and in the case of markers very close to use a cluster. the problem is that both individual and marker clusters are displayed, I want the displayed tokens not to cluster all clusters all the time

 <script type="text/javascript">
		var sliderControl = null;
                    //creating layers

Sorry for some comments, some of them are real code made as debug comments

2016:

Leaflet.MarkerCluster.LayerSupport, .

LayerSupport LeafletSlider.

:

var markers = L.layerGroup();

// Add all your markers into `markers` Layer Group.

// Check into MCG Layer Support!
// Add to map first before checking in.
L.markerClusterGroup.layerSupport().addTo(map).checkIn(markers);

var sliderControl = L.control.sliderControl({
  position: "topright",
  layer: markers,
  range: false,
  follow: 3
});

map.addControl(sliderControl);
sliderControl.startSlider();
