我有麻烦的问题，使我的图标按钮对齐到中间的卡。正如你可以看到的图片，图标按钮是在顶部附加到顶部的卡。
我怎样使它在卡片的一半大小处相遇？有什么建议吗？（我希望按钮位于卡片的中间）
尝试过：我尝试过在Row小部件中添加填充或换行，但没有效果。

child: new Container(
            height: 150.0,
            width: MediaQuery.of(context).size.width,
            child: new Card(
              color: Colors.white,
              elevation: 8.0,
              child: Row(
                  mainAxisAlignment: MainAxisAlignment.spaceEvenly,
                  crossAxisAlignment: CrossAxisAlignment.center,
                  children: [
                    Column(
                      children: [
                        IconButton(
                            onPressed: () {},
                            icon: Icon(Icons.sticky_note_2),
                            iconSize: 35,
                            color: Colors.lightBlue),
                        Text(

尝试以下代码并将mainAxisAlignment: MainAxisAlignment.center,设置为每个Column小工具。请参阅layout和Align

Container(
  height: 150.0,
  width: MediaQuery.of(context).size.width,
  child: Card(
    color: Colors.white,
    elevation: 8.0,
    child: Row(
      mainAxisAlignment: MainAxisAlignment.spaceEvenly,
      crossAxisAlignment: CrossAxisAlignment.center,
      children: [
        Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            IconButton(
                onPressed: () {},
                icon: Icon(Icons.sticky_note_2),
                iconSize: 35,
                color: Colors.lightBlue),
            Text(
              "Notes",
              style: TextStyle(
                color: Colors.black,
                fontSize: 15,
              ),
            ),
          ],
        ),
        Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            IconButton(
              onPressed: () {},
              icon: Icon(Icons.quiz),
              iconSize: 35,
            ),
            Text(
              "Quizzes",
              style: TextStyle(
                color: Colors.black,
                fontSize: 15,
              ),
            ),
          ],
        ),
        Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            IconButton(
              onPressed: () {},
              icon: Icon(Icons.auto_stories),
              iconSize: 35,
            ),
            Text(
              "Ebooks",
              style: TextStyle(
                color: Colors.black,
                fontSize: 15,
              ),
            ),

问题是什么？

您在row中使用了居中对齐，但在column内部没有使用。现在column取整行的高度，但column的子代没有对齐center。

溶液：

尝试在每列中添加mainAxisAlignment: MainAxisAlignment.center

当前代码：

Row
mainAxisAlignment:MainAxisAlignment.center
|_Column
|_Column
|_Column

所需代码：

Row
mainAxisAlignment:MainAxisAlignment.center
|_Column
  mainAxisAlignment:MainAxisAlignment.center 👈 Add these to every column
|_Column
  mainAxisAlignment:MainAxisAlignment.center
|_Column
  mainAxisAlignment:MainAxisAlignment.center

用下面的代码替换你的"Row"小部件，这将解决你的问题。
