Can you explain how the Voyager system works?

The Voyager system in the context of Android usually refers to internal navigation mechanisms or custom solutions for managing transitions between screens (Activity, Fragment). Generally, the mechanics of such a system include managing the screen stack, passing data between them, and handling component lifecycle.

For example, the Voyager system can implement navigation through a navigation stack, where each new screen is placed on top of the previous one, and returning is done by removing the top element of the stack. This allows users to move forward and backward through the application's interface.

When talking about the specific Voyager library (for example, in Kotlin Multiplatform), it provides a type-safe and declarative way to describe navigation, where navigation states are represented by objects, and transitions are functions, simplifying navigation management and testing.
