Jetpack Compose Standards

Priority: P0

Implementation Guidelines

State Hoisting

  • •Pattern: Screen (Stateful) -> Content (Stateless).
  • •Events: Pass lambda callbacks down (onItemClick: (Id) -> Unit).
  • •Dependencies: NEVER pass ViewModel to stateless composables.

Performance

  • •Recomposition: Use @Stable / @Immutable on UI Models.
  • •Lists: Always use key in LazyColumn / LazyRow.
  • •Modifiers: Reuse Modifier instances or extract to variables if stable.

Theming (Material 3)

  • •Tokens: Use MaterialTheme.colorScheme and MaterialTheme.typography.
  • •Hardcoding: **No Hardcoded Colors**: Use Theme.

Anti-Patterns

  • •Side Effects: **No SideEffects in Composition**: Use LaunchedEffect.
  • •ViewModel pass-through: **No VM deep pass**: Hoist state.
