How to use the @better-scroll/shared-utils.Direction.Default function in @better-scroll/shared-utils

move(delta: number) {
    delta = this.hasScroll ? delta : 0
    this.movingDirection =
      delta > 0

        ? Direction.Positive
        : Direction.Default

    let newPos = this.currentPos + delta

    // Slow down or stop if outside of the boundaries
    if (newPos > this.minScrollPos || newPos < this.maxScrollPos) {
      if (
        (newPos > this.minScrollPos && this.options.bounces[0]) ||
        (newPos < this.maxScrollPos && this.options.bounces[1])
      ) {
        newPos = this.currentPos + delta / 3
      } else {
        newPos =
          newPos > this.minScrollPos ? this.minScrollPos : this.maxScrollPos
      }
    }
    return newPos

        ? Direction.Positive
