Set up Flutter routing for deep linking by configuring declarative router patterns with go_router to synchronize page structures with URLs. This approach enables reliable screen transitions and URL-driven navigation for web and mobile applications.

Handle nested navigation in Flutter by building independent sub-flows using Navigator or Router patterns. This manages multi-step journeys like setup wizards or tab stacks without breaking the parent app structure.

Pass data between Flutter screens and receive return values using Navigator push and pop mechanisms. This sends arguments to target routes cleanly and returns results directly to the calling screen.

Use declarative routing in Flutter when your app needs URL synchronization or deep-link support, typically for web platforms. Choose imperative navigation with Navigator for straightforward, linear screen-to-screen push and pop flows.

Manage multi-step checkout as a nested navigator flow in Flutter to isolate the purchase journey. This keeps the sub-flow independent from the main app route stack, ensuring clean back-button handling.

Handle back-button events during nested Flutter navigation by managing independent Navigator stacks within sub-flows. Proper router configuration ensures the back button targets the active nested flow before exiting to the parent route.
