### **简介**
|
||
> 包含当前ViewPort及滚动位置等信息
|
||
- pixels：当前滚动位置
|
||
- maxScrollExtent：最大可滚动长度。
|
||
- extentBefore：滑出ViewPort顶部的长度；
|
||
- extentInside：ViewPort内部长度；此示例中屏幕显示的列表部分的长度
|
||
- extentAfter：列表中未滑入ViewPort部分的长度；此示例中列表底部未显示到屏幕范围部分的长度
|
||
- atEdge：是否滑到了Scrollable Widget的边界

|
||
### **基本用法**
|
||
> 抽象类，不可被实例化
|
||
- FixedScrollMetrics，它是实现此接口的不可变对象
|
||
- 下方Demo中，在接收到滚动事件时，参数类型为ScrollNotification，它包括一个metrics属性，它的类型是ScrollMetrics
