Resize Scalebar on Zoomin or Zoom out

[sush123]

I have a scale bar displayed in the ARCGIS map with QML and i need to resize this scale bar when ever i zoom in and zoom out.

This is how i am setting scalebar in Mapview

    ScaleBar{                
        anchors.left: mapView.left
        anchors.bottom: mapView.bottom
        anchors.bottomMargin: 80
        anchors.margins: 10 * scaleFactor
        map:mapView
           }

How can i resize scalebar just like it works in googlemaps.

Got solution by setting map.scale to the width of scale bar
