### **简介**
|
||
> 用于绘制滚动条的CustomPainter。
|
||
- 与CustomPainter子类化的CustomPainters不同，只有当shouldRepaint返回true时才重绘
|
||
- 当滚动条消失和滚动位置发生变化的时候painter需要重绘而不是重新构建

||

|
||
|
||
const String contentText1 = '''
|
||
### **基本使用**
|
||
> 当ScrollbarPainter不再使用的时候，必须在ScrollbarPainter上调用dispose
|
||
- 除非自定制Scrollbar的需求，基本上我们都可以使用Scrollbar
|
||
- Scrollbar的源码其实就是基于ScrollbarPainter封装的
|
||
- demo中将Scrollbar源码进行提取使用
|
||
- CupertinoScrollbar 同样也是使用ScrollbarPainter的最好学习示例
