Is there a way do get some window insets, but in a way which respects the already consumed insets, while not having to go with Modifier.windowInsetsPadding nor Modifier.windowInsetsTopHeight and the equivalents?
My use case is that I got a layout where for one of the items, I want the contentPadding: PaddingValues parameter that it takes to respect insets, but doing something like PaddingValues(horizontal = 16.dp) + WindowInsets.safeDrawing.asPaddingValues() means that it simply gets the insets even if they are consumed, since that’s how asPaddingValues works.
From what I can tell, this functionality hooked together though some ModifierLocals which modifiers like windowInsetsTopHeight respect by being ModifierLocalConsumer themselves, so I don’t see a good entrypoint for my code to get the benefits of the existing functionality there.
Is there some way for me to get access to it in a reasonable non-hacky way since ModifierLocalConsumedWindowInsets is internal in the foundation compose package?

I am sorry for the ping, but this feels right up your alley @Alex Vanyo
The tl;dr is: Can I can the non-consumed insets in a composable without doing it through a Modifier with the current APIs?

And if not, for my use case regarding using non-consumed insets for contentPadding of a composable, is there something else I can do?

[Alex Vanyo]

There’s Modifier.onConsumedWindowInsetsChanged , which allows pulling out the consumed insets and using that in measurement or layout.

Alex, thank you so much! I completely missed this API 🫣

Ended up with something like this for my specific use case

var consumedWindowInsets by remember { mutableStateOf(WindowInsets(0.dp)) }
MyComposable(
  contentPadding = PaddingValues(horizontal = 16.dp) + WindowInsets.safeDrawing.exclude(consumedWindowInsets).only(WindowInsetsSides.Horizontal).asPaddingValues(),
  modifier = Modifier.onConsumedWindowInsetsChanged { consumedWindowInsets = it },
)

I guess that this means that for the first composition I will be wrongly assuming that the consumed window insets are 0.dp, since I need to initialize it with something until the lambda runs for the first time. But it works!! which is the important bit here.

I was looking here https://developer.android.com/jetpack/compose/layouts/insets#padding-modifiers for a solution to my issue, but I couldn’t find anything. Is this function mentioned anywhere else which I may have missed? I would love to read more about it to make sure I am using it correctly too if any such docs exist.

I created an issue to get an easier api to get this notconsumed window insets here: https://issuetracker.google.com/issues/300949347
