encounter the same issue. I just change line 102 to _controller.reverse(); Thanks

encounter the same issue. I just change line 102 to _controller.reverse(); Thanks

like this (97-108) lines

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

would be nice to have this fixed in a new release
