How do I get the map's visible coordinates?

[Mikeeeeee]

Hi!
How do I get the map's visible coordinates?
This my code:

import QtQuick 2.12
import QtQuick.Window 2.12
import QtLocation 5.12
import QtPositioning 5.12

Item {
    visible: true
        width: 480
        height: 720
//    width: Screen.width
//    height: Screen.height

        property double old : 19
        property double now

    Rectangle
    {
        anchors.fill: parent
        color: "#eee"

        Component.onCompleted:
        {
            circle.center = src.position.coordinate
            circle1.center = src.position.coordinate
            circle2.center = src.position.coordinate
            maps.center = src.position.coordinate
        }

        PositionSource
        {
            id: src
            active: true
            updateInterval: 1000
            onPositionChanged:
            {
                circle.center = position.coordinate
                circle1.center = position.coordinate
                circle2.center = position.coordinate
            }
        }

        Plugin
        {
            id: plugin
            name: "osm"
            PluginParameter { name: "osm.useragent"; value: "My great Qt OSM application" }
            PluginParameter { name: "osm.mapping.host"; value: "http://osm.tile.server.address/" }
            PluginParameter { name: "osm.mapping.copyright"; value: "All mine" }
            PluginParameter { name: "osm.routing.host"; value: "http://osrm.server.address/viaroute" }
            PluginParameter { name: "osm.geocoding.host"; value: "http://geocoding.server.address" }
            PluginParameter { name: "osm.places.host"; value: "http://geocoding.server.address" }
        }

        Map
        {
            id: maps
            anchors.fill: parent
            plugin: plugin
            gesture.enabled: true
            gesture.acceptedGestures: MapGestureArea.PinchGesture | MapGestureArea.PanGesture | MapGestureArea.FlickGesture
            gesture.flickDeceleration: 3000
            zoomLevel: 19

            onZoomLevelChanged:
            {

            }

            minimumZoomLevel: 1

            focus: true


        }
    }
}

Tried to do so, but the coordinates are not returned. Please tell me how to do it.

So you can find the center. But how can you determine the size of the visible map?

console.log("coordinate center:" + visibleRegion.center())

[Mikeeeeee]

It's works

                console.log("coordinate ctnter:" + visibleRegion.center())
                console.log("coordinate geoshape:" + visibleRegion.boundingGeoRectangle())
