### **简介**
> BoxConstraints为抽象类，我们可以使用BoxConstraints,一个不可边的约束布局，renderBox布局
- 一个尺寸尊重一个BoxConstraints，当且仅当，以下关系式的成立：
minWidth <= Size.width <= maxWidth
minHeight <= Size.height <= maxHeight
约束本身必须满足这些关系：
0.0 <= minWidth <= maxWidth <= double.infinity
0.0 <= minHeight <= maxHeight <= double.infinity
double.infinity是每个约束的合法值。
