We also cover bridging StateFlow and SharedFlow for shared ViewModels, using AI to audit KMP dependency readiness, and highlight useful CMP libraries like Calf and Compose Cupertino. Plus, a look at Super Mario Bros ported to Kotlin and a Senior KMP role at Fanatics. ### **The Log** The only Kotlin Multiplatform and Compose Multiplatform news you actually need to know. ⛱️ [Google Summer of Code 2026 Is Here: Contribute to Kotlin](https://blog.jetbrains.com/kotlin/2026/03/gsoc-2026-contribute-to-kotlin/?ref=commonmain.dev) The Kotlin Foundation is joining [Google Summer of Code (GSoC) 2026](https://summerofcode.withgoogle.com/?ref=commonmain.dev)! If you are a student or an eligible contributor looking to spend your summer working on a real-world open-source project, this is your chance to make a meaningful impact on the Kotlin ecosystem while also benefiting from the mentorship of experienced engineers. ### Expect Actual Technical deep dives, or solving the "how-the-hell-do-I-test-this" problems.

It also makes it easy to write over-specified, flaky tests without realising it. Here's why you should learn coroutine testing without it first. 🏁 [Crossing the Finish Line: StateFlow & SharedFlow in Kotlin Multiplatform](https://www.kmpbits.com/posts/stateflow-kmp?ref=commonmain.dev) In this article, we’ll go from a quick recap of `StateFlow` vs `SharedFlow`, through the KMP bridge problem, all the way to a working shared ViewModel consumed natively on both Android (Jetpack Compose) and iOS (SwiftUI). We’ll also cover the real gotchas that don’t usually make it into the docs. 🤖 [Using AI to Check Your KMP Readiness](https://touchlab.co/using-ai-to-check-your-kmp-readiness?ref=commonmain.dev) Before migrating an Android project to Kotlin Multiplatform, you need to answer one question: are your dependencies ready? Here's how to combine deterministic scripts with AI-powered research to check, without wasting time or money. ### The Dependency Graph Curated libraries, tools and plugins that won't break your Gradle build. - [**Calf**](https://github.com/MohamedRejeb/Calf?ref=commonmain.dev) Calf is a library that allows you to easily create adaptive UIs and access platform specific APIs with Compose Multiplatform (Adaptive UI, File Picker, WebView, Permissions...). - [**Compose Cupertino**](https://github.com/alexzhirkevich/compose-cupertino?ref=commonmain.dev) Compose Cupertino is a Kotlin Multiplatform library for the Compose Multiplatform UI framework. It provides various UI components for making native-looking iOS applications. - [**Kapacity**](https://github.com/DeveloprOfThings/Kapacity?ref=commonmain.dev) Kapacity is a lightweight, zero-allocation Kotlin Multiplatform library for Android and iOS designed to make handling digital data sizes safe, strictly typed, and intuitive. - [**Kotlinx DateTime Fun**](https://github.com/sami-eljabali/kotlinx-datetime-fun?ref=commonmain.dev) Useful extension functions for `kotlinx.datetime` library. ### Target: Production Showcase of real-world apps proving KMP is ready for prime time.
