嗨，我在颤振方面相对较新。我正在尝试为家务制作一张卡片，而卡片的这个特定部分给我带来了问题。我不知道，为什么每行之间有这么大的垂直空间（每行基本上有两个按钮）。我已经尝试了几件事来解决这个问题，但我现在放弃了，来这里寻求建议。谢谢！布局视图。

试试这个，去掉Sizedbox(height:100)

另外，您可以删除SizedBox(width : 8)行内部并尝试 Row(mainAxisAlignment:MainAxisAlignment.spaceBetween, children:[]); 

Positioned(
          bottom: 15,
          left: 15,
          child:  Column(
              children: [
                Row(
                 mainAxisAlignment:MainAxisAlignment.spaceBetween, 
                  children: [
                    ElevatedButton(
                      style: TextButton.styleFrom(
                        padding: EdgeInsets.zero,
                        minimumSize: Size(40, 20),
                        backgroundColor: colorSet.buttonForeground,
                      ),
                      onPressed: () {},
