Rectangle {
    x: (parent.width - width) / 2
    y: (parent.height - height) / 2
    width: 10
    height: 10

} 

// My source
Rectangle {
    x: (parent.width - width) / 2
    y: (parent.height - height) / 2
    width: indicator.control.checked ? 10 : 0 // modified, replaces "visible"
    height: width                             // modified
    radius: width / 2
    color: parent.border.color
    Behavior on width { NumberAnimation { easing.type: Easing.OutBack } } // added
}
