When writing NumberAnimations, PropertyAnimations and other animations that have "property" or "properties" fields, the first item on the list is the code snippet for creating new dynamic properties, i.e. "property type name: name" is produced.

For almost all of the cases, the user would instead like to write "property: " or "properties:".

    NumberAnimation {
        property: ""
        // Not this:
        property type name: name
        
    }
