Is it somehow possible to override the provided WindowInsets for a platform? Id like to mimic the system UI of Android on Desktop for some of my screenshots.

I’d say try to provide a fake inset number for the ModifierLocalConsumedWindowInsets which the inset modifiers seem to be using, but it looks like that’s internal in the foundation.layout library.
But maybe I am missing something and you can create something that is a ModifierLocalProvider<WindowInsets> and provide your own insets in there without having to access the internal value itself.
Maybe can get some inspiration from here https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/[…]PaddingModifier&ss=androidx%2Fplatform%2Fframeworks%2Fsupport and provide just a hardcoded WindowInsets value? 👀
I have no idea how modifier locals work and how similar they are to composition locals, but I assume they work the same way, propagating down the tree of your composables

Ahh, thank you! I wouldnt have thought of that myself. Will try it out later today and share the results 😃

Do tell if it works (or doesn’t), I am curious 👀 😅

The TL;DR; is that I dont think I can make that work because the key for it is marked internal. BUT, I dont think I fully understand how it all mangles together (sorry, I dont have time to look deeper into it right now 😅).
I can for example use Modifier.windowInsetsPadding(bottom=48.dp) which under the hood uses said key to provide some insets, but I think my scaffold eats that up since its just generic insets, and as such not excluded in the scaffold logic? Whereas I would need to specifically use WindowInsets.navigationBar in order for it to pass through to my NavigationBar, etc. Dunno if that makes sense, fwiw the desktop logic: actual val WindowInsets.Companion.navigationBars: WindowInsets get() = ZeroInsets is what Im trying to override, so that my NavigationBar actually has that extra padding, instead of it being added to my entire layout (=system navigation bar doesnt have same color as in app NavigationBar).

It was worth a try 😅

Oh well 😄 I wonder if I can make it work with reflection? This is just used in tests, so performance isnt that big of a deal 🙂
