compose-samples VS filament

Basic understanding of Jetpack Compose.

The compose-samples repo has a comprehensive list of samples ranging from low to complex projects which might be worth a look.

And what was learned from Flutter has produced something I consider even more interesting: Compose UI (https://developer.android.com/jetpack/compose) and JetBrains' Compose Multiplatform (https://www.jetbrains.com/lp/compose-mpp/)

Now, same story, in the current documentation the list is replaced by a single UserMessage without any explanation of the previous example. It just says "For a more advanced use case, displaying a list of user messages on screen, check out the Jetsnack Compose example." .

As for the strange infix syntax, you're correct - it's not important (for Dart anyway). Kotlin supports writing code that have DSL like syntax making things like typesafe HTML or Jetpack Compose possible.

This is what Jetpack Compose according to the Android Developers team;

Anyone know much about how this compares to Filament by Google?

Have you tried Filament? https://google.github.io/filament/

There are a handful of other examples out there of high-level shading languages - Cg (long deprecated), whatever Filament Material system uses (example), and various GLSL preprocessors (example).

Filament is an option: https://github.com/google/filament

Google Filament is the first thing that comes to mind for me, not sure if that's appropriate for what you're looking for though.

- 3D graphics, i used filament in KMM and it was outstanding, didn't find bindings or similar pub

Google Filament is a C++ engine with Kotlin bindings for Android. Very high quality code on both sides https://github.com/google/filament

You can make a game engine in Java/Kotlin. But, that doesn't mean you should. For professional work, your choices are pretty much C, C++ and Rust. https://stride3d.net/ is a good counter-example to my claim. But, the far more common method is a high-level language interface over a C++ implementation. https://github.com/google/filament is an awesome example of a Kotlin interface over a C++ implementation. Unity is C# over C++.
