1909333 - Change `AcornWindowSize.getWindowSize` to use `LocalConfiguration.current.smallestScreenWidthDp` instead of `screenWidthDp`

Status: RESOLVED WONTFIX

(Fenix :: Design System and Theming, task, P1)

Description

[Noah Bond [:007]]

LocalConfiguration.current.screenWidthDp gets the app window's current width in the current orientation. Instead, we might want to use smallestScreenWidthDp.

smallestScreenWidthDp functions similarly to the sw600dp, smallest width resource property, where the smallest width possible, regardless of orientation is returned.

smallestScreenWidthDp should be used IFF we want the minimum width used to enforce a screen size minimum AND we don't want to just show a particular layout whenever the width threshold is met.

• In other words, just because a phone may fall into the Medium size category when in landscape, we might still want to show the Small window layout. (Similar to how sw600dp functions today)

Confirm this behavior change/parity with Crystal and Jules first.

I'm integrating this over in Bug 1909554. We should instead have two use paths:

1. Having logic forks for determining when the window size is large enough to branch for UI differences.
2. Having logic forks for determining when the physical hardware is large enough for certain UI or feature differences.
