Android Navigation Standards

Priority: P0

Implementation Guidelines

Type-Safe Navigation

  • •Library: Navigation Compose 2.8.0+.
  • •Routes: Use @Serializable objects/classes instead of String routes.
  • •Arguments: No manual bundle parsing. Use .toRoute<T>().

Structure

  • •Graphs: Split large apps into nested navigation graphs (navigation extension functions).
  • •Hoisting: Hoist navigation events out of Screens. Composable screens should accept callbacks (onNavigateToX).

Anti-Patterns

  • •Hardcoded Strings: **No String Routes**: Use Typed Objects.
  • •Passing NavController: **No NavController in UI**: Hoist events.
