父控件滑动处理

[zengcanxiang]

private fun scrollParent(deltaX: Float): Offset {
        val parentIsBetweenPages = parentState.isBetweenPages()
        if (!parentIsBetweenPages && !parentState.canScrollInGestureDirection(deltaX)) {
            parentDragActive = false
            return Offset.Zero
        }

        // PagerState.dispatchRawDelta uses pager scroll coordinates. For LTR horizontal pagers,
        // those coordinates are the opposite of the user's drag delta, so invert both input and
        // return value.
        val consumed = -parentState.dispatchRawDelta(-deltaX)
        if (consumed.absoluteValue > 0f) {
            parentDragActive = true
        }
        return Offset(x = consumed, y = 0f)
    }

中使用-parentState.dispatchRawDelta(-deltaX)，会在甩手幅度过大的时候，导致可能滑动很多页

想知道这个思路是为什么？是怕父控件还需要在网上分发吗？
