Kotlin 2.0 & Jetpack Compose Formatting Reference
Kotlin 2.0 (K2) & Coroutines

Full support for Sealed Interfaces, Value Classes (@JvmInline), Flow<T>, and suspend functions without modifying coroutine scope.

Security Safeguards

Treats Kotlin code strictly as text data for formatting. NEVER compiles, runs kotlinc / ./gradlew CLI commands, or executes binaries on the host machine.

Jetpack Compose & Modifiers

Preserves Jetpack Compose @Composable hierarchy, remember states, and modifier chain order (Modifier.fillMaxWidth().padding()).

Multiline Raw Strings & KDoc

Triple-quoted raw string templates ("""raw string"""), annotations (@JvmStatic), and KDoc documentation (/** */) are preserved verbatim.
