                children: [

            ),
          ),
        ],
      );
    }

    // 按钮行创建
    Widget buttonSection = Container(
        child: Row(
          mainAxisAlignment: MainAxisAlignment.spaceEvenly,
          children: [
            buildButtonColumn(Icons.call, "打电话"),
            buildButtonColumn(Icons.near_me, "找我"),

      ),
      
      body: ListView (
        
        children: [
          // 图片模块
          imageSection,
          // 标题模块
          titleSection,
          // 按钮模块
          buttonSection,
          // 正文模块
          textSection,
