	## ConstrainedBox

	>
	一个基础布局控件,添加额外的限制条件(constraints)到child上

	### 构造方法
	``` dart
	ConstrainedBox({
	Key key,
	@required this.constraints,
	Widget child
	})
	```

	### 属性介绍
	* constraints: 添加到child上的额外限制条件,其类型为BoxConstraints,限制各种最大最小宽高
	* child: ConstrainedBox中的内容Widget

	### 其他用法
	* constraints值为BoxConstraints.expand时,提供width或者height,那么限制(Constraints)将严格使用给出的width或者height值
