How do I get if something is near using proximity sensor in android with QML

I'm trying to use the ProximitySensor in QML. I didn't find examples of how to use it. I'm using QtSensors 5.0. I tried get if something is near by calling the reading property, but this property only have this properties: deleteLater, objectName and timestamp. I tried this ProximityReading.near, but it returns undefined. I also tried this proximitySensor.close(), but it returns that proximitySensor was not defined. The proximity sensor is working fine, because I tested in my smartphone the property reading.timestamp and the values was updated properly.

My code is something like this:

import  QtSensors 5.0
ProximitySensor {
    id: proximity
    active: true
    dataRate: 100

    onReadingChanged: {
        // How do I get if something is near?

    }

    onErrorChanged: {

    }
}

The type info may not be property interfaced to be read by Creator, but the properties and methods should be there nonetheless. Try this:

onReadingChanged: {
     if (reading.near) console.log("it is near")
     else console.log("it is far")
}
