Multiplatform rectangle drawing (Android, Linux)

Is Android Native capable of using single codebase to have very basic UI (drawing rectangles) on Android and Linux? And maybe iOS?

I found some Android specific examples, text only hello world for multiplatform ones and hopefully outdated claim “no true cross-platform Kotlin GUI” at https://cantina.co/kotlin-native-naughty-or-nice/

I want to simply draw some rectangles, with program running on multiple platforms. Is it feasible? Are there some examples/docs about this?
