1. Why would you choose StateFlow over LiveData in 2026?
Answer
StateFlow is Kotlin-first, works naturally with coroutines, supports structured concurrency, and integrates seamlessly with Jetpack Compose.
LiveData still works, but StateFlow has become the preferred choice for modern Android applications.
Example
private val _uiState = MutableStateFlow(HomeUiState()) val uiState: StateFlow<HomeUiState> = _uiState
Compose:
val state by viewModel.uiState.collectAsStateWithLifecycle()
