How to get value from another qml

[Atr0p0s]

Hello everyone!
I have 2 qml files:
main.qml that contains StackView and loader of another file:

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!

@Atr0p0s I've never tried this with a loader, but you can put a signal in your serialport-view.qml file to return the value of isPortOpened. Maybe someone else can chime in on doing this through a loader...

@mzimmers but I can't connect the signal from serial-port.qml with an object from Main.qml because Loader doesn't create an Object from it at startup...

@mzimmers I don't know how, but Connection with Loader.item works even if the item is null.

Connections {
    target: serialportLoader.item
}

Thank you! :)
