Deep Link and Restoration

When handling deep links or state restoration, ensure predictable redirects and stable app states.

Links and Redirects

• Cold vs Warm Links: A cold link opens the app from closed; a warm link routes within an already running app. Both must reach the correct state.
• Auth Flow: Route unauthenticated requests for protected content to a login screen, passing a redirect target. On success, seamlessly navigate to that target.
• Redirect Loops: Prevent infinite cycles by maintaining clear auth-state boundaries and avoiding circular redirect dependencies.

State Restoration

• RestorationMixin: Use to persist UI state across app restarts. Combine with the router to maintain navigation history.
• Router Integration: Ensure deep links re-hydrate not just the destination, but also essential parent routes or dependencies required by that destination.

Testing

• Verify behavior of both cold and warm deep links.
• Test authentication redirects and loop prevention.
• Assert proper fallback or error handling for invalid paths.
