Currently we have canScrollForward / canScrollBackward state in lazy* APIs - this would be generically useful for all scrollable components and would allow developers to more easily implement features such as scroll to top / bottom buttons, indicators to show that there is more scrollable content in a certain direction and buttons (such as arrows in a scroll bar) to manually scroll by a fixed delta.

It would also allow us to make other performance / optimization improvements that would be worth investigating:

Only dispatch scroll deltas if we can scroll in that direction (i.e we are not at the end of the scrollable component)
Not dispatch scroll deltas or overscroll if we can scroll in neither direction (e.g the scrollable bounds are smaller than the viewport)

Is there any update when the alpha04 will be available? We need it to target api 31 because of the PendingIntent mutability flags missing in alpha03.

I'll schedule it for the next release. Note that alpha04 is a complete turn-down of the library where all APIs are marked as Deprecated, so you'll also want to start removing your usages of the library.

Marked as fixed.
