How does navigation stack management work in Xamarin.Forms?

Xamarin.Forms maintains a navigation stack where pages are pushed and popped to manage user flow.

Navigation in Xamarin.Forms is stack-based. Each page pushed onto the Navigation stack is stored in memory until popped. NavigationPage manages this stack internally. Developers must handle back navigation, modal pages, and deep linking carefully to avoid memory leaks or navigation inconsistencies. Shell navigation simplifies this further with route-based navigation.
