+## **ListBody**
+
+>
+该控件沿着给定的轴顺序排列子节点
+* ListBody是一个不常直接使用的控件，一般会配合ListView或者Column等控件使用
+* 在主轴上，子节点按照顺序进行布局，在交叉轴上，子节点尺寸会被拉伸，以适应交叉轴的区域
+* 在主轴上，给予子节点的空间必须是不受限制的（unlimited），使得子节点可以全部被容纳,ListBody不会去裁剪或者缩放其子节点
+
+### 构造方法
+``` dart
+ListBody({
+  Key key,
+  this.mainAxis = Axis.vertical,
+  this.reverse = false,
+  List<Widget> children = const <Widget>[],
+})
+```
+
+### 属性介绍
+* mainAxis：排列的主轴方向，Axis.vertical/horizontal
+* reverse：是否反向
+* children：ListBody中的内容Widget
