Flutter如何让Column子组件分别靠顶部底部对齐实现列表项布局

布局修改方案 #

你只需要调整两个Column组件的配置即可实现标题贴顶、副标题贴底的效果，具体修改步骤如下：

• 你的左侧封面图固定高度为85，先给两个Column外层套高度为85的SizedBox，保证列高度和图片高度对齐，避免高度自适应内容导致对齐失效
• 给两个Column添加两个属性：
  1. mainAxisSize: MainAxisSize.max：让Column占满父级SizedBox的全部高度
  2. mainAxisAlignment: MainAxisAlignment.spaceBetween：核心控制属性，自动将Column内部的第一个子元素贴在列顶部，第二个子元素贴在列底部

核心修改后的代码示例 #

Row(
  // 可选添加：保证行内元素垂直居中对齐
  crossAxisAlignment: CrossAxisAlignment.center,
  children: [
    // 左侧图片部分保持不变
    ClipRRect(
      borderRadius: BorderRadius.circular(10.0),
      child: _gameDetails!.locationInfo == null
          ? const SizedBox()
          : CachedNetworkImage(
              imageUrl: _gameDetails!.locationInfo!.pictures.elementAt(0),
              width: 85,
              height: 85,
              fit: BoxFit.cover,
              placeholder: (context, url) => const SizedBox(
                  child: Center(child: CircularProgressIndicator()),
                  width: 10,
                  height: 10),
            ),
    ),
    const SizedBox(width: 10,),
    Expanded(
      flex: 7,
      // 新增固定高度SizedBox
      child: SizedBox(
        height: 85,
        child: Column(
          crossAxisAlignment: CrossAxisAlignment.start,
          // 新增两个属性
