Preserving and recovering the navigation state in Jetpack Compose involves the following steps:
Define a NavHost component: This component is responsible for managing the navigation state of the application. It should be placed at the root of the application hierarchy.
Create a NavController: This controller is used to navigate between different destinations in the application. It can be created using the NavHost's NavController property.
Declare the destinations: A destination is a screen or a view that the user can navigate to. It should be declared using the NavHost's composable functions.
Declare the navigation routes: A navigation route defines the path to reach a destination. It can be declared using the NavController's composable functions.
Handle back navigation: Back navigation is handled by the NavController automatically. If your app requires additional actions or validation before going back, it can be implemented using the NavController's popBackStack() function.
Save and restore the navigation state: The navigation state can be saved and restored using the NavController's onSaveInstanceState() and onRestoreInstanceState() functions. This ensures that the user can resume the app from where they left off, even if the app is killed or restarted.
These steps ensure that the navigation state is preserved and recovered in Jetpack Compose.
