iOS swipe back gesture with Custom page route

i am trying to use Android Page Transition on iOS. i set fullscreenDialog to true this works well but the Swipe back gesture on iOS is disabled. How can i enable it back still using the Android Page Transition.

Navigator.push(
                              context,
                              MaterialPageRoute(
                                builder: (context) => Chat(
                                  peerid: peerid,
                                  userid: widget.matchesId,
                                ),
                                fullscreenDialog: true
                              ),
                            );

Also i have try to use this plugin still yet getting the-same result. The swipe back gesture on iOS still disabled...
