根据flutter_boost 官网介绍，回传后then 方法回调 支持的是 native 页面退出时，传递参数给上一个flutter页面

// 1. 从Flutter页面打开一个Native页面，并处理返回结果
InkWell(
child: Container(
    padding: const EdgeInsets.all(8.0),
    margin: const EdgeInsets.all(8.0),
    color: Colors.yellow,
    child: Text(
        'open native page',
        style: TextStyle(fontSize: 22.0, color: Colors.black),
    )),
onTap: () => BoostNavigator.instance
    .push("ANativePage") // Native页面路由
    .then((value) => print('retval:$value')),
),

同样的方法 push flutter页面后，发现 then 回调没有执行

 //这样 then 不会执行
                 BoostNavigator.instance.push(
                            "catPluginSettingClockPage",
                            withContainer: false,
                          ).then((value){

                            //进行页面刷新
                            _catDeviceSettingController.getDeviceClock();
                            print("从定时列表返回到设置页");
                          });

于是，直接使用flutter 提供的路由跳转方法，结果then回调可以执行

 //这样 then 才会执行
                          Route route = MaterialPageRoute(builder: (context) => ClockCleanPage());
                          Navigator.push(context, route).then((value){
                              //进行页面刷新
                              _catDeviceSettingController.getDeviceClock();
                              print("从定时列表返回到设置页");
                          });
