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.
