jetc.dev Newsletter Issue #323

Published: 2026-07-21

Sorry for a somewhat abbreviated issue this week, as I am “under the weather”… an expression that I have never fully understood. What weather? And, aren’t I usually under whatever the weather is? 🤔

Regardless, this week we see a few new alphas, see how to reorganize your base fragment “junk drawer” for Compose, and see Lottie’s first official Compose support.

Ooooo… What Did We Get?

Reviewing the release notes for the latest Jetpack Compose update!

The alpha Compose BOM is now at 2026.07.00. This adds Material3 1.5.0-alpha24 and Remote Compose 1.0.0-alpha15.

Killing the BaseFragment: How to Build Truly Reusable Screens in Jetpack Compose

For a long time, perhaps even today, your project had some sort of “base Fragment” class, where you stuck all sorts of common behaviors. Praveen Yadati explores where you should put those common behaviors in a Compose-first UI setup, from loading indicators to navigation aids to analytics.

Prashant Panwar (Bluesky) created JellyFab, a very jiggly floating action menu composable. This post explains how the effects were created.

Medium: The Compose Clinic: Three Symptoms, One Patient

Angelina Andronova examines three common symptoms (frozen UI, stutter on scrolling, general sluggishess), and sees what mistakes trigger those in Compose UI development.

Resource Roundup

100% pure code!

GitHub: LottieFiles / dotlottie-android

We have had third-party Lottie libraries for Compose, and now the Lottie team itself joins the party! This library brings us DotLottieController and DotLottieAnimation() to play dotLottie files for Compose for Android. The third-party Compottie is still a good candidate for Compose Multiplatform.

GitHub: 07jasjeet / LazySurface

Jasjeet Singh is building an infinitely-sized container, where items in the container are positioned relative to each other, and the container expands to fit. This is great for diagrams of arbitrary size. The UI includes full gesture support, and it works on all major Compose Multiplatform targets.

GitHub: crowded-libs / artboard

The Crowded Innovations Libs team created a gallery for Compose Multiplatform @Preview-annotated functions. These get rendered on a Kotlin/Wasm UI, with each preview image getting a stable UI (e.g., to pass to designers). See https://crowded-libs.github.io/artboard/ for a demo.

GitHub: jjrodcast / TextKit

Jorge Rodriguez built a rich text editor for Compose Multiplatform, supporting all major targets. In addition to the standard editor features (formatting bar, undo/redo, etc.), TextKit supports triggers (for you to intercept things like @-style mentions or slash commands) and embedded blocks.

GitHub: hajma32 / Tilo.Compose

Petr Heinz is working on a map and GIS library, powered by OpenStreetMap. It supports “tiled raster layers (WMS, XYZ, and custom tile stores), projection-aware rendering, vector geometry and styling, label placement, feature selection, interactive drawing, spatial indexing, and extension points for custom data sources and coordinate transformations”.

GitHub: j-roskopf / Andy

GitHub user j-roskopf offers us a developer desktop companion for controlling devices and emulators. Features range from AVD management and a scrcpy-style mirror to GUIs in front of common adb commands.

Notable Releases

Maps for Android is up to 8.4.0, adding rotation to cluster items, the ability to opt out of keyboard focus traversal, plus bug fixes and dependency updates.

Circuit is out with 0.35.1, introducing CircuitSaver, better Kotlinx Serialization and SavedState support, and more.

Orbit MVI published 12.0.0, with a unified Container/ContainerHost model with configurable defaults, side effect delivery modes, and more!

A Very Particular Set of Skills

Adding Compose capabilities to your coding agents!

Ali Sadeghi created KMPilot, a mix of skills, agents, and what appears to be a project template to help guide agents when building Kotlin Multiplatform projects. See this Medium post for more.

Also, the Code with the Italians team continues working on their skills repository.
