我要使用FlutterReact按钮插件在新的我的应用程序。
但当我把React按钮，并按下图标，预览图标框显示在右侧和主视图被移动到左侧网站。1
这里是项目代码显示图片和React按钮。

class CommunicationItem extends StatefulWidget {
  const CommunicationItem({@required this.communication});
  final Communication communication;

  @override
  _CommunicationItemState createState() => _CommunicationItemState();
}

class _CommunicationItemState extends State<CommunicationItem> {
  @override
  Widget build(BuildContext context) {
    return Card(
      margin: const EdgeInsets.symmetric(horizontal: 10, vertical: 5),
      elevation: 2,
      child: ClipRRect(
        borderRadius: const BorderRadius.all(Radius.circular(5)),
        child: Column(
          children: [
            Image.asset('assets/images/showImage.png'),
            spaceH8,
            Padding(
              padding: const EdgeInsets.symmetric(horizontal: 20),
              child: Row(
                children: [
                  FlutterReactionButtonCheck(
                    onReactionChanged: (reaction, index, isChecked) {
                      print('reaction selected index test: $index');
                    },
                    reactions: data.reactions,
                    initialReaction: data.defaultInitialReaction,
                    selectedReaction: data.reactions[0],
                  ),
