They most likely added a dependency that transitively depends on Compose, possibly for some prebuilt UI. EDIT: Another possibility is that they started out with some template app that happened to have the Compose dependencies included in the Gradle build script, and with this being a Flutter app, they had no reason to touch the Gradle script beyond just adding the Flutter dependency. Assuming the app doesn't have R8 enabled, all of Compose would remain in the APK unused.

What does gradle mean? I always thought it was a portmanteau of "cradle to grave"

  It’s a build tool for Java, and Android then too, I guess?

    Correct. Gradle is the standard build tool used for Android apps.

Ok, I took a closer look at the analysis page linked to from the main article. There does seem to be a decent amount of Kotlin code written by Rabbit themselves, mostly UI for the settings screens, as well as some networking-related stuff (WebSockets, Wi-Fi, etc), hardware-related things such as the camera, OTA updates, etc. Basically, things that make sense to be handled closer to the operating system itself. Interestingly, as far as I can tell, Compose is only being used for a "hardware test activity". The rest of the Kotlin side of things seems to use the traditional Android UI stack with activities, views and fragments. That makes three distinct UI frameworks in use on the Rabbit R1 - Flutter, Compose and traditional Android.

  Thanks for the thorough lookup, I have worked with launcher, IoT apps on Android. And, Flutter (or any cross platform) would never be an option for this kind of projects. It’s not just because we need easy access to the hardware (camera, Bluetooth, etc) but also the different protocols (MQTT, RTSP, etc) are very complex.
