Enhancement: Upgrade AndroidX Lifecycle to 2.8.x #192

@github-actions

Description

@github-actions

Summary

The project uses androidLifecycleGrouped = "2.7.0" for all lifecycle-related artifacts (lifecycle-viewmodel-compose, lifecycle-runtime-ktx, lifecycle-livedata-ktx, etc.). Lifecycle 2.8.x is now stable and includes important improvements.

Key Improvements in Lifecycle 2.8

  • LifecycleEventEffect and LifecycleStartEffect/LifecycleResumeEffect composables — cleaner replacements for DisposableEffect with LocalLifecycleOwner.
  • collectAsStateWithLifecycle improvements for safer Flow collection tied to UI lifecycle.
  • viewModel() KMP support — multiplatform ViewModel for future KMP migration.
  • Bug fixes and improved SavedState integration.

Proposed Changes

  1. In Versions.kt, update:
    const val androidLifecycleGrouped = "2.8.x"  // e.g. "2.8.7"
  2. All lifecycle artifacts using this version constant update automatically:
    • lifecycle-viewmodel-compose
    • lifecycle-viewmodel-ktx
    • lifecycle-livedata-ktx
    • lifecycle-runtime-ktx
    • lifecycle-viewmodel-savedstate
  3. Review usages of DisposableEffect(lifecycleOwner) in the codebase and consider migrating to the new LifecycleEventEffect API where applicable.
  4. Run all tests to confirm no regressions.
