Check the QML component existence. How?

[bogong]

Hello all!

I need to check QML component existence. Something like

Component.onCompleted: {
    if (QmlCustomComponent) {
    
    } else {
    
    }
}

I am downloading *.qrc file from server and need to check if component is into it.

Qt.createComponent from javascript, Loader from QML, and QQmlComponent from C++ all appear to be viable options for the situation described. Loader doesn't appear to allow loading the component without instantiating an instance.
