'unity - how to update an object when a serialized field is changed?

I'm sure the question is already out there but I cannot find it, sorry.

I'm trying to sync a Serialized field of an object with other of its components.

let's say I have a field "size" which should impact the object transform scale:

[SerializeField]
int _size;

I'm looking for an event handler or something that allow me to do:

void onSerializedPropertyChange() {
    transform.localScale = new Vector3(_size,_size,_size);
}

Does a method like that exists ?

In the end the idea would be to work with more than one property and to tweak object properties while preview the result.

 public class UIAnimatorGroup:MonoBehaviour
    {
        public UIAnimatorTransform _animatorTransform;

    }

[System.Serializable]
public class UIAnimatorTransform
{
    [HideInInspector] public Matrix4x4 LocalMatrix4X4; // ??
    [HideInInspector] public Matrix4x4 GobleMatrix4X4;
    [HideInInspector] public UIAnimatorTransform parent;

    [SerializeField] 
    [OnChangedCall("onSerializedPropertyChange","UIAnimatorTransform")]
    private Vector3 position;

    [SerializeField] 
    [OnChangedCall("onSerializedPropertyChange","UIAnimatorTransform")]
    private Vector3 rotation;

    [SerializeField] 
    [OnChangedCall("onSerializedPropertyChange","UIAnimatorTransform")]
    private Vector3 scale;

    public void onSerializedPropertyChange()
    {
        SetLocalMatrixByTransform();
        CalculateGobleTransform();
    }
}

How about [ExecuteInEditMode]?

Then you can use the normal Update() method.
