import { EventEmitter } from './shared-utils/event'

export class MScrollConstructor extends EventEmitter {
  content!: HTMLElement
  options!: OptionsConstructor
  scroller!: Scroller
  constructor(el: HTMLElement, options?: Options) {
    super(['beforeScrollStart', 'scrollStart', 'scroll', 'scrollEnd'])

我自己看到吗没有看到则这个事件的注册和使用，我看的对吗？beforeScrollStart 这个事件是不是从头到尾没有用到过？
