Critical Patterns Reference

A. ViewModel Implementation (State-Action-Event Pattern)

All ViewModels follow the State-Action-Event (SAE) pattern via BaseViewModel<State, Event, Action>.

Key Requirements:

• Annotate with @HiltViewModel
• State class MUST be @Parcelize data class : Parcelable
• Implement handleAction(action: A) - MUST be synchronous
• Post internal actions from coroutines using sendAction()
• Save/restore state via SavedStateHandle[KEY_STATE]
• Private action handlers: private fun handle* naming convention
