Flutter实现Row行末位置图标文本适配：短文本居右、长文本省略

核心是通过Expanded+Flexible组合分配Row的布局空间，同时控制文本溢出逻辑，调整后代码如下：

locationView() {
    return Padding(
      padding: const EdgeInsets.fromLTRB(16, 20, 16, 0),
      child: Column(
        crossAxisAlignment: CrossAxisAlignment.start,
        children: [
          Row(
            mainAxisAlignment: MainAxisAlignment.spaceBetween,
            children: [
              // 左侧标题区域保持不变
              Row(
                mainAxisAlignment: MainAxisAlignment.start,
                children: [
                  bellazTitle("Hey, Emily", 22),
                ],
              ),
              const SizedBox(width: 10,),
              // 改动1：用Expanded包裹右侧整个位置区域，仅占用左侧标题剩下的可用宽度
              Expanded(
                child: Row(
                  // 改动2：右侧区域内容右对齐，短文本时图标+文本整体靠最右展示
                  mainAxisAlignment: MainAxisAlignment.end,
                  crossAxisAlignment: CrossAxisAlignment.center,
                  children: [
                    Image.asset(
                      "lib/Assets/location.png",
                      height: 22,
                      width: 16,
                    ),
                    if (featureName != null)
                      Padding(
                        padding: const EdgeInsets.only(left: 8.0),
                        // 改动3：用Flexible包裹文本，限制文本最大宽度不超出父容器剩余空间
                        child: Flexible(
                          child: Text(
                            "${featureName}, ${locality}",
                            style: TextStyle(
                              color: apptitleColor,
                              fontSize: t4Size,
                            ),
                            maxLines: 1,
                            overflow: TextOverflow.ellipsis,
                          ),
                        ),
                      )
                  ],
                ),
              )
            ],
          ),
          Padding(
            padding: const EdgeInsets.only(top: 2.0),
            child: Text(
              "Welcome to Bellaz!",
              style: TextStyle(
                color: extraLightColor,
                fontSize: t5Size,
              ),
            ),
          )
        ],
      ),
    );
  }

• 地址较短时：Expanded分配的剩余宽度足够完整展示图标+文本，MainAxisAlignment.end让整体内容靠右侧展示
• 地址较长时：Flexible限制文本最大宽度为Expanded分配宽度减去图标宽度，超出部分自动触发省略号，不会挤压左侧标题区域，也不会出现布局溢出
