Android - Jetpack Compose

Modern declarative UI toolkit for building native Android interfaces.

Key Concepts

State Management

Compose provides several ways to manage state:

• remember: Survives recomposition
• rememberSaveable: Survives configuration changes
• mutableStateOf: Creates observable state
• derivedStateOf: Computed state that updates when dependencies change

@Composable
fun Counter() {
    var count by remember { mutableStateOf(0) }
