This package works with in Android but not in ios

[ziagit]

I use pusher_client: ^2.0.0 it works without any problem with Android but when run my project on ios simulator I get error in the console.
when I run flutter run I get the following errors.

Xcode's output:

    error: the following command failed with exit code 0 but produced no further output

      channel = pusher?.subscribe("private-chat." + widget.room.id.toString());

      pusher?.onConnectionStateChange((state) {
        print(
            "previousState: ${state?.previousState}, currentState: ${state?.currentState}");
      });

      pusher?.onConnectionError((error) {

      });

      channel?.bind('chat-event', (event) {
        setState(() {});
      });
    } catch (e) {
      print(e.toString());
    }
  }
}

But the moment I comment out the above file and pusher_client: ^2.0.0 in pubspec.yaml and then run flutter run my application gets run on ios simulator.
Can anyone help please
