Hi, thanks for reporting.
As a temporary workaround, you can probably:
- unregister your margin transformer
- register a MarginPageTransformer with an offset of 0
- viewpager2.requestTransform()
- viewpager2.adapter.notifyItemInserted()
- revert back to the original transformer
It should be indistinguishible from the user perspective when done while viewPager.getScrollState() == SCROLL_STATE_IDLE (at that stage, there is no visible offset).
If it's not there, OnPageChangeCallback will notify you once the viewpager changes to SCROLL_STATE_IDLE.
Alternatively, if you don't want the animation, a notifyDatasetChanged() should work fine. Especially if you're using Fragments, as they will be kept around.
Apologies for the extra steps. We'll look into it!
