Flutter List.map()时获取index

通常使用List渲染，写法如下:

  Widget _medicPlanDisplayContent(BuildContext context, PlanModels planModels) {
    return Container(
      child: Column(
        children: planModels.plan.map((planModel) {
          return _medicPlanDisplayItem(context, planModels, planModel);
        }).toList(),
      ),
    );
  }

但是当需要同时获取index和element的时候，Flutter就比较麻烦了，如下：

      Flex(
          direction: Axis.horizontal,
          children: visitTimeInfoBean.videoAppointmentList
              .asMap()
              .map((index, element) =>
                  MapEntry(index, _voiceVideoInfoItem(index, element)))
              .values
              .toList()),

还是kotlin比较爽,哈哈

 for ((index, value) in array.withIndex()) {
        println("the element at $index is $value")
    }
