I was looking through some Compose widgets, and couldn't find where they are literally drawing their contents, is there a good example some where? Does it boil down to a canvas object at some point?

[Francesc]

yes, compose draws straight to Canvas using Skia

[Kirill Grouchnikov]

Yes, go down the source code and you'll eventually get to Canvas composables

[Adam Brown]

great, thanks

[Colton Idle]

Skia everywhere!

Modifier.drawBehind etc is the most typical in-app usage

Anyway, you won't find anything related to Skia or (platform) Canvas in any of the common directories. To find it you'll need too look in Foo.android.kt files

[Kirill Grouchnikov]

The Canvas composables will be in the common directories though
