Open the file ../../flutter/.pub-cache/hosted/pub.dartlang.org/custom_radio-0.1.2/lib/custom_radio.dart and override _updateState method:

 void _updateState() {
    setState(() {
      if (widget.checked && _controller.status != AnimationStatus.completed) {
        _controller.forward();
      } else {
        // _controller.reverse().then((Null value) {
        //   setState(() {});
        // });
        _controller.reverse();
      }
    });
  }
