jetc.dev Newsletter Issue #321
Published: 2026-07-07
This week, we start off with some bug fixes to Compose and updates to related libraries. We look at Nav3 migrations, Grid(), and effects. And we see somebody creating an alternative Compose for Desktop renderer, to get away from AWT/Swing.
Ooooo… What Did We Get?
Reviewing the release notes for the latest Jetpack Compose update!
The Compose BOMs are up to 2026.06.01. The production BOM mostly points to 1.11.4. The beta BOM points generally to 1.12.0-beta02. Both appear to be mostly bug fixes.
Compose Material3 is up to 1.5.0-alpha23. They added an expressive timepicker component, not to be confused with a timepicker that be all like 😑. They also added “new non-interactive variants of standard list item and segmented list item which follow Material Expressive specifications” and fixed bugs.
Remote Compose has reached 1.0.0-alpha14. RemoteDocumentPlayer now has a typefaceResolver, and they added RemoteDensityBehavior.
Glance is out with 1.3.0-alpha02 with several additions and changes.
Glance for Wear OS is up to 1.0.0-alpha13, principally about changes to squircle behavior, because of course.
Wear Compose has reached 1.7.0-alpha05, with lots more stuff for one-handed gestures.
Nav3 has 1.1.4 and 1.2.0-alpha05. And we also got these Compose-related updates:

Migrating App to Navigation 3: Pain, Overtimes, and Hotfixes
Tetiana Synytsyna’s team ported 170+ screens from Navigation 2 to Navigation 3. While it went smoothly overall, there were issues along the way, and this post outlines them and how the team addressed them.
Medium: Build Complex 2D Layouts With the New Compose Grid
Reza Ramesh relishes the fact that with the experimental Grid() composable that we finally have a first-class non-lazy 2D layout component. Reza walks through the comparison with CSS Grid, gives us a tour of the track/gap/cell structure, and demonstrates the Grid() DSL.
Medium: Adding Dark Mode to Google Maps in Jetpack Compose
Carlos Mota
(Bluesky)
illustrates how to teach Maps for Compose about your light/dark theme system, given that Maps for Compose wraps a MapView and by default is oblivious to whether your app wants a light or dark set of map tiles.
DrawBox Goes Multiplatform
Akshay Sharma maintains DrawBox, a Compose library for drawing on a canvas. In this post, Akshay explained the migration process from a Compose for Android library to full Compose Multiplatform support, and points out the benefits gained from that work beyond broader platform support.
Fun With Sliders and Compose
Ahmed El-Helw (Mastodon) explores a few options for implementing a particular UI pattern: a slider with adjacent buttons, where those buttons vanish while the slider is being manipulated by the user. As is often the case, the simple solutions do not work quite right and the right solution will require more work to be fully production-ready.
Inside Compose Side Effects: RememberObserver and the Composition Lifecycle
Jaewoong Eum
(Mastodon, Bluesky)
continues his exploration of the innards of Compose, this time explaining how effect handlers work. Along the way, we see how a key affects how we remember and why we pay a coroutine price for these handlers… unless we are careful.
