android-jetpack-compose

Declarative UI toolkit for building native Android interfaces with state management and recomposition optimization. Modern declarative UI toolkit for building native Android interfaces. Compose provides several ways to manage state: Lift state up to make composables stateless and reusable: Bad: Good: Bad: Good: Bad: Good: - Provides state management primitives: remember for recomposition survival, rememberSaveable for configuration changes, mutableStateOf for observable state, and derivedStateOf for computed values - Emphasizes state hoisting to create stateless, reusable composables and integrates with ViewModel and StateFlow for app-level state - Includes efficient recomposition patterns using stable keys for lists, side effect hooks ( LaunchedEffect , DisposableEffect , SideEffect ), and computed state to avoid expensive operations during composition - Covers Material 3 theming, Navigation Compose for routing, and lazy layouts (LazyColumn, LazyVerticalGrid) with sticky headers and adaptive grids - remember : Survives recomposition - rememberSaveable : Survives configuration changes - mutableStateOf : Creates observable state - derivedStateOf : Computed state that updates when dependencies change - android-architecture : MVVM and clean architecture patterns - android-kotlin-coroutines : Async operations in Compose
