/// Calls all the status listeners.

  void notifyStatusListeners(PagingStatus status) {
    assert(_debugAssertNotDisposed());

    if (_statusListeners!.isEmpty) {
      return;
    }

    final localListeners = List<PagingStatusListener>.from(_statusListeners!);
    localListeners.forEach((listener) {
      if (_statusListeners!.contains(listener)) {
        listener(status);
      }
    }

Any reason we should expect _statusListeners to never be null?
In case you dispose the paging_controller and a callback still happens this can be null.

It would be safer to use _statusListeners?without any downside here?

I guess it is similar as in #246

@EdsonBueno I created a PR for your review

was this really fixed ? i'm still having the same issue in my crash analytics even thought i upgraded the package to the last version

Would be good to get @cornetthomas's PR merged in and a fix out for this. Very much a live issue right now @EdsonBueno.

Is this library still maintained? The PR looks very straightforward

Any progress on this fix ?
Is there a chance to get this released ?
