A device that is folded at 90 degrees and in landscape mode could show a keyboard
on the bottom half. Open it all the way and it could show master on one side and details on other.

Start with the Android foldables guide linked in the issue and determine the native APIs and supported platform scope for the proposed package. The issue is complete only when a concrete package, API surface, and behavior for foldable device states are defined for the supported platforms.
