Does this have any updates?

an...@google.com <an...@google.com> #4Feb 9, 2022 02:29PM

Work is in progress, but we can't say right now in what release it will be added. We didn't yet resolve all the api questions we have about this component

Experimental LazyLayout

Promotes LazyLayout api from internal to experimental.

Bug: 197851917
Fixes: 166591700
Test: Added more tests for LazyLayout
Relnote: New experimental LazyLayout API is introduced. This allows to build your own components like LazyColumn of LazyVerticalGrid. Notes that the API is on its early stages and can be changed in the future releases.
