- Bump kotlin-gradle-plugin 1.9.22 -> 2.1.20 (root + buildSrc) - Adopt the new Compose Compiler Gradle plugin (org.jetbrains.kotlin.plugin.compose) in app and convention plugins - Drop composeCompiler version constant and composeOptions blocks - Replace removed -Xopt-in flag with -opt-in - Bump KSP to 2.1.20-1.0.31 to match Kotlin Fixes Gurupreet#182 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
ktfmt-gradle 0.12.0 fails with 'Generic error during file processing' once Kotlin 2.x is on the buildscript classpath. 0.22.0 supports Kotlin 2.x and also formats *.kts build scripts, hence the repo-wide reformat (no functional changes).

- AGP 8.2.2 -> 8.7.3 (compileSdk 35 supported from AGP 8.6) - Gradle wrapper 8.5 -> 8.9 (required by AGP 8.7.x) Fixes Gurupreet#185 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
- Replace compose/material3 version constants with composeBom - Strip explicit versions from BOM-managed artifacts - Import the BOM platform on every configuration that receives Compose artifacts (implementation, debugImplementation, androidTestImplementation, :data) - Migrate API removals that come with Compose 1.7 / Material3 1.3: SmallTopAppBar -> TopAppBar, rememberRipple -> material3 ripple - Update the outdated README Compose badge to the BOM version Fixes Gurupreet#186 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
All lifecycle artifacts (viewmodel-compose, viewmodel-ktx, livedata-ktx, runtime-ktx, viewmodel-savedstate) move together via the shared androidLifecycleGrouped version. Fixes Gurupreet#192 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
- navCompose 2.7.7 -> 2.8.9; add kotlinx-serialization-json 1.8.0 - Apply the Kotlin serialization plugin in gmail and tiktok demos - Gmail: string routes -> @serializable route objects - TikTok: TikTokScreen becomes a serializable sealed interface; the profile route carries a typed userId argument read via toRoute(), bottom bar selection uses NavDestination.hasRoute Fixes Gurupreet#193 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Summary
Upgrades Navigation Compose from 2.7.7 to 2.8.9 and adopts type-safe navigation, as proposed in #193.
Build changes
Versions.kt:navCompose2.7.7 → 2.8.9; newkotlinxSerializationJson = "1.8.0"kotlinx-serialization-jsonadded to the sharedkotlinDependenciesgrouporg.jetbrains.kotlin.plugin.serialization(2.1.20, matching Kotlin) available frombuildSrcand applied in the two demo modules that define routesType-safe route migrations
"home"/"detail"/"create"string routes →@Serializableroute objects (GmailHomeRoute,GmailDetailRoute,GmailCreateRoute)TikTokScreenis now a serializable sealed interface; the profile route carries a typed argument —data class Profile(val userId: String)read viabackStackEntry.toRoute<…>()instead ofarguments?.getString("userId")!!— and the bottom bar selection usesNavDestination.hasRoute(...)instead of comparing route stringsThe Wear OS nav graph in the cryptoapp demo intentionally stays string-based: it uses
androidx.wear.compose:compose-navigation, which has its own API surface.Closes #193
