Flutter slidable package can be closed programatically?

Question

As I've seen in the Slidable package documentation you should, at least in theory, close the ActionPane with the Slidable.of(context).close() function but it returns the following error:

My code:

 onTap: () {
              Slidable.of(context).close();
            },

My error:

The method 'close' was called on null.
Receiver: null
Tried calling: close()
