Loader {
        id: serportLoader
        active: false
        source: "serialport-view.qml"
    }

On button pressing I push this file to stack:

serportLoader.active = true;
stackView.push(serportLoader.item);

The second qml looks like this:

ColumnLayout {
    SerialPortHandler {
        id: portHandler
        property bool isPortOpened: false
...

So, can I somehow get a value of isPortOpened of the portHandler object?

With console.log(serportLoader.item.portHandler.isPortOpened); I get TypeError: Cannot read property 'isPortOpened' of undefined.

I just want to get result of the work from the second qml file. Perhaps can you advise a better approach?
Thanks in advance!
