Inside Jetpack Compose
summary
Describes how Jetpack Compose updates the UI by demonstrating a runnable Kotlin sample that removes a node after 3 seconds from a simple tree and prints changes to the console. The talk covers the Kotlin compiler plugin that rewrites composables into start/end group calls, the slot table that stores the UI structure, state change detection via the snapshot system and read observers, and how the composer/applier applies minimal updates using a gap buffer to efficiently delete and insert nodes.
