    A control that can be dismissed by dragging in the indicated `dismiss_direction`. When dragged or flung in the
    specified `dismiss_direction`, it's content smoothly slides out of view.

    After completing the sliding animation, if a `resize_duration` is provided, this control further animates its
    height (or width, depending on what is perpendicular to the `dismiss_direction`), gradually reducing it to zero
    over the specified `resize_duration`.
