@yoyo930021 I see there is work in progress regarding this issue. I’m using Vuetify and have the slot type issue with its virtual scroller. Is there any workaround to manually type hint the correct slot type from “any”? I didn’t find a way for that. Wondering if it’s currently even possible (just manual hinting).

It’s a lot of work. It will take a lot of time.

If you know ahead of time something takes a lot of work, then you just implied you know the direction towards the end goal, just think about how to achieve it while your Typescript skill gets better.
