We explore **Metro DI patterns**, adaptive layout systems that handle everything from phones to foldables with zero hardcoded pixels, and a guide to handling **exceptions in Kotlin Flows**. Plus, we look at how to fix production bugs using **Claude Code** and the **Kotzilla MCP Server**, and feature new roles at Booz Allen and CoreWillSoft. ### **The Log** The only Kotlin Multiplatform and Compose Multiplatform news you actually need to know. 🏅 Kotlin Ecosystem Mentorship Program: Results and Winners In the [Kotlin Ecosystem Mentorship Program](https://blog.jetbrains.com/kotlin/2026/02/kotlin-ecosystem-mentorship/?ref=commonmain.dev) pilot, mentors and mentees worked together on real Kotlin open-source projects to make their first meaningful community contribution. Four pairs successfully completed the two-month program, and one eligible pair was randomly selected in the prize drawing to receive the grand prize – a trip to KotlinConf 2026 in Munich! ### **The Main Thread** Community's most insightful threads, curated from social media platforms and websites. ▶️ [How to Handle Exceptions in Kotlin Flows](https://www.youtube.com/watch?v=tJS7D2cC4eU&ref=commonmain.dev) Exceptions can be thrown from within our flows, just like anywhere else in our Kotlin code. In this video, we'll see the right and wrong places to put your try-catch blocks, and how to use the catch operator. ### Expect Actual Technical deep dives, or solving the "how-the-hell-do-I-test-this" problems. SPONSORED ****Stop treating Kotlin like a black box! 🧠** To build truly performant multiplatform apps, writing code that just "works" isn't enough. We need to understand what the compiler is actually doing under the hood. That’s why I highly recommend [****Practical Kotlin Deep Dive**](https://skydoves.gumroad.com/l/kotlin-deep-dive?a=705284499&ref=commonmain.dev) by skydoves. This isn't a basic syntax guide, it breaks down Kotlin internals, bytecode, and coroutines. It’s been a total game-changer for me when writing and optimizing shared code. If you want to level up your Kotlin and KMP skills to a senior standard, you need this on your desk. [Get the Book ](https://skydoves.gumroad.com/l/kotlin-deep-dive?a=705284499&ref=commonmain.dev) 🏎️ [Drop the Clutch: Three Metro DI Patterns Every KMP Developer Should Know](https://www.kmpbits.com/posts/drop-the-clutch?ref=commonmain.dev) I already covered Koin Annotations in a [previous article](https://www.kmpbits.com/posts/koin-annotations?ref=commonmain.dev). What follows isn’t a migration guide. It’s a look at three specific patterns that come up in every real KMP project and where Metro’s behaviour changed how I think about dependency injection. 🧰 [Fixing production issues in a Kotlin Multiplatform app with Kotzilla MCP Server and Claude Code](https://medium.com/kotzilla/fixing-production-issues-in-a-kotlin-multiplatform-app-with-kotzilla-mcp-server-and-claude-code-62c3305b34ae?ref=commonmain.dev) In this article, I fixed real production issues on a Kotlin Multiplatform app entirely from inside Claude Code using Kotzilla MCP Server. Two things made that loop work. 🔔 [Push Notifications in Mobile Apps Using Kotlin Multiplatform (KMP): A Practical Guide](https://medium.com/@techdynasty/push-notifications-in-mobile-apps-using-kotlin-multiplatform-kmp-a-practical-guide-15bd82b194e8?ref=commonmain.dev) In this article, we’ll walk through how to implement push notifications in a KMP project, share as much logic as possible, and handle the platform-specific parts cleanly using `expect`/`actual`. ### LazyColumn Compose Multiplatform tips, tricks, and code snippets. 🧑‍🎨 [Building a Production-Grade Adaptive Layout System in Kotlin Multiplatform — From Phone to Foldable](https://medium.com/@mr.califer/building-a-production-grade-adaptive-layout-system-in-kotlin-multiplatform-from-phone-to-foldable-26a50f3ba2d2?ref=commonmain.dev) This article is about building a layout system that is **intentionally* adaptive. One that knows what device it’s running on, what orientation it’s in, whether a hinge is separating the screen in two, whether the iPad is in Split View, and makes a precise, correct decision every single time — with zero hardcoded pixel values and zero platform-specific layout code in your feature screens. ✍️ [Jetpack Compose Animations](https://doveletter.dev/docs/compose-animations?ref=commonmain.dev) A growing catalog of self contained Jetpack Compose animation examples by skydoves. Every entry is a single composable file you can read end to end, with the constants you can tweak and a written walkthrough of how the motion is built. ### The Dependency Graph Curated libraries, tools and plugins that won't break your Gradle build. - [**Kmp Resources Unfold**](https://plugins.jetbrains.com/plugin/31310-kmp-resources-unfold/?ref=commonmain.dev) A professional productivity tool designed for **Android Studio** and **IntelliJ IDEA** developers. It bridges a major gap in the IDE by providing visual management and robust import capabilities for assets across all your Kotlin Multiplatform (KMP) modules. - [**Gradle Lighthouse**](https://github.com/dev-vikas-soni/gradle-lighthouse?ref=commonmain.dev) An enterprise-grade build intelligence plugin for Android and Kotlin Multiplatform. Think of it as "Google Lighthouse" for your module graph. - [**FastCollect**](https://github.com/sooniln/fastcollect?ref=commonmain.dev) A library for high-performance primitive collections in the Kotlin ecosystem. As a drop-in replacement for standard Kotlin collections, FastCollect generally reduces memory usage by 4–5× and improves CPU performance by 2-4× (and perhaps >10× on some iteration heavy workloads). - [**native-kt**](https://github.com/husker-dev/native-kt?ref=commonmain.dev) Gradle plugin for convenient C/C++ integration into a Kotlin Multiplatform project. Supports JVM, Android, Native, Wasm and JS targets. ### Careers Kotlin Multiplatform job postings and opportunities.
