     */
    children: React.ReactElement;

    /**
     * Base class name for transition states (e.g., 'my-transition' for 'my-transition-enter').
     */
    className: string;

    /**
     * Controls whether the transition is in the entered (true) or exited (false) state.
     */
    in: boolean;

    /**
     * Duration of the transition animation in milliseconds.
     */

     * If true, unmounts the child element when the transition exits. Defaults to false.
     */
