Stopping a realtime DB query

[MustafaCa]

Hi Eddy,

I need to stop the following query when the user switches to a different tab.

    firebase.query(
      onQueryEvent,
      "/groups/" + groupKey + "/messages/",
      {
        singleEvent: false,
        orderBy: {
          type: firebase.QueryOrderByType.CHILD,
          value: 'createdAt' // mandatory when type is 'child'
        }
      }
    );

I do see an off method in the RT DB source, but not sure how to use it.

Any suggestions?

Thanks, Mustafa.
