android - 如何将文本放入带有 flutter 的滑动器中？

Question

我已经尝试了一段时间将文本放入 flutter 的滑动小部件中，但我不能，我一直在搜索，但我找到的只是图像。这是我的代码

Container(
    padding: EdgeInsets.only(top: 10.0 ),
    color : Colors.black12,
    child: Swiper(
      itemWidth: _screenSize.width *0.7,
      itemHeight: _screenSize.height * 0.5,          
      layout: SwiperLayout.STACK,
      itemBuilder: (BuildContext context, int  index) {
        return ClipRRect(
          borderRadius: BorderRadius.circular(20.0),
          child: Image.network("https://colourlex.com/wp-content/uploads/2017/04/Spinel-black-painted-swatch-47400-opt.jpg",fit: BoxFit.fill),

        );
      },
      itemCount: 3,                    
    ),
  );

您可以复制粘贴运行下面的完整代码
您可以使用 Stack 将文本放在图像上

代码 fragment

itemBuilder: (BuildContext context, int index) {
      return Stack(
        children: <Widget>[
          Center(
            child: Image.network(
              "https://colourlex.com/wp-content/uploads/2017/04/Spinel-black-painted-swatch-47400-opt.jpg",
              fit: BoxFit.fill,
            ),
          ),
          Center(
            child: Container(
              //width: 90,
              //height: 90,
              //color: Colors.white,
              child: Text("Your Text here No ${index}",
                  style: TextStyle(
                    color: Colors.white,
                  )),
            ),
