|
||
> 一个将child 放置于中心
|
||
- 如果它的尺寸受到外界约束，并且widthFactor和heightFactor 为null，则widget将会尽可能的大。
|
||
- 如果它的尺寸不受外界约束，并且相应的大小为null，则widget将会匹配child widget的大小
|
||
- 如果相应尺寸不为null，则widget的相应尺寸将是child 尺寸和尺寸因子的乘积（例如：widthFactor是2.0,那么widget的宽度始终是其child widget宽度的2倍）

const String Text1 = """
|
||
### **基本用法**
|
||
> widthFacto/heightFactor 非null，将其宽/高度设置为子宽/高度乘以此系数
|
||
- 如果widthFactor是2.0，那么widget的宽度将始终是其子宽度的两倍。
|
||
- 如果heightFactor是2.0，那么widget的高度将始终是其子高度的两倍。
