How to get value of transitionDuration in C# for Unity UI Toolkit

Question

My existing code for this task is:

private VisualElement _creditSection;

    private void Start()
    {
        var rootElement = uiDocument.rootVisualElement;
        
        _creditSection = rootElement.Q("CreditSection");

        Debug.Log(_creditSection.style.transitionDuration.value);
    }

However, I am receiving null for this in console. I understand it's because the value is of object type, but I don't know how to get the value of the transition duration.

are you maybe getting null for _creditSection due to that query rootElement.Q("CreditSection") failing? Like is it printing out null in the console or do you rather get a NullReferenceException? — derHugo

@derHugo I'm sure It's correct. stackoverflow.com/a/77999961/16948694 — Mfa Xyz

By chance, I discovered that I am able to get the value of transitionDuration using this code:

print(_creditSection.resolvedStyle.transitionDuration.First().value);

It seems that _creditSection.style is used for setting values, whereas resolvedStyle is used for getting values. Utilizing LINQ, we can extract the first value of transitionDuration.
