Answer
Shell's URI routing maps external links to route hierarchies. Register routes, then map incoming platform deep links (Android intent filters, iOS Universal Links) to a GoToAsync call with the corresponding route and parameters. The route path can encode navigation depth like //home/orders/details?id=42.
// From platform deep-link handler
await Shell.Current.GoToAsync($"//home/orders/details?id={orderId}");Real-world example Tapping a push-notification link opens the app directly on order #42's details page by translating the payload into a Shell route.
