如何使用cdk-virtual-scroll-viewport检测开始滚动？

Question

I'm looking for an event or any method to detect when the user starts scrolling through the list.

I know the elementScrolled Method, but the Observable emits way too often.

Do you maybe have any workaround for this issue?

I would be very happy about any suggestions :)

Answer 1

Have you tried to use 'auditTimeInMs'

auditTimeInMs? number
Time to throttle the scroll events.
