I am looking for the current coordinates of the vehicle

I am looking for a function that takes the vehicle’s current GPS value as a QGC.
This code seems to be related.

src/FlightMap.qml

   // Update ground station position
    Connections {
        target: QGroundControl.qgcPositionManger

        onLastPositionUpdated: {
            if (valid && lastPosition.latitude && Math.abs(lastPosition.latitude)  > 0.001 && lastPosition.longitude && Math.abs(lastPosition.longitude)  > 0.001) {
                gcsPosition = QtPositioning.coordinate(lastPosition.latitude,lastPosition.longitude)
                if (!firstGCSPositionReceived && !firstVehiclePositionReceived && allowGCSLocationCenter) {
                    firstGCSPositionReceived = true
                    center = gcsPosition
                    zoomLevel = QGroundControl.flightMapInitialZoom
                }
            }
        }
    }

But I do not know where “lastPosition” is set.

Somebody save me
