Getting signal strength on iPhoneX emulator causes crash

This issue occurs on iPhoneX emulator and similar, but it works fine on other emulators such as iPhone7

Calling this

Future<Null> _getWifSignalStrength() async {
    int l = await Wifi.level;
    setState(() {
      _signalStrength = l;
    });
  }

Causes a crash and this stack trace:
