两个Scroll互相监听彼此的滑动-卡顿问题

scroller1: Scroller = new Scroller()
scroller2: Scroller = new Scroller()
flag = true


Scroll(this.scroller1) {}
.onTouch(() => this.flag = true)
.onScroll((x, y) => {
  if (this.flag) this.scroller2.scrollBy(x, y)
})

Scroll(this.scroller2) {}
.onTouch(() => this.flag = false)
.onScroll((x, y) => {
  if (!this.flag) this.scroller1.scrollBy(x, y)
})
