Kotlin Multiplatform UI state management requires a single source of truth for UiState with predictable lifecycle behavior. You select a pattern like MVI or shared presenters, shape UiState, separate one-time effects, and wire per-platform lifecycles for Android, iOS, desktop, and web targets.

Handling one-time effects in KMP requires separating them from the observable UiState. You enforce a contract where user actions are inputs, the state is a single observable stream, and effects are processed independently to ensure predictable UI behavior across Android and iOS targets.

Yes, Android ViewModel with StateFlow is supported alongside shared presenters and MVI patterns. It provides guidance on KMP ViewModel abstractions to ensure consistent architecture and predictable state delivery across Android, iOS, desktop, and web platforms.

A testable UI state architecture enforces a contract of one observable state, separated effects, and user actions as inputs. It defines UiState shaping and effect handling requirements to ensure consistent, testable behavior across Android, iOS, and desktop targets.

Cross-platform lifecycle behavior complicates state management because differing platform lifecycles disrupt the single source of truth. This requires specific patterns and proper lifecycle handling to maintain predictable UiState delivery across Android, iOS, desktop, and web targets.

Yes, MVI patterns are explicitly supported for shaping shared UI state. It provides a roadmap to align MVI with project needs, enforcing a contract of one observable state, separated effects, and user actions as inputs for consistent architecture across screens and teams.
