How can I build custom UI that works like `Dialog(...

# compose

How can I build custom UI that works like Dialog() -- with a full-screen overlay/scrim in Compose? The source of Dialog does this by using rememberComposeSceneLayer, which is internal.

Or put another way, how can I make a nested composable fill the screen, rather than being constrained to its parents constraints/z-order?

Why not just use Dialog itself?

I'd like to change the scrim color animate the open/close

[Ivan Matkov]

Scrim color is customizable on Multiplatform, but it's not animated yet, true.

Use Popup. You can find similar usage cases in some material3 components

aha, Popup was exactly what I was looking for! Thank you :)

I feel like the docs for Dialog (at least where I am, on compose desktop) should say "you probably want Popup!"
