Is it possible to use the same ViewModel for data exchange between two fragments during navigation?

Yes, you can use the same ViewModel for data exchange between two fragments when navigating, provided that the ViewModel is tied to a shared lifecycle owner, such as an Activity. In this case, both fragments access the same ViewModel, allowing them to exchange data without directly linking the fragments.

Example:

// Getting the ViewModel associated with the Activity
val sharedViewModel = ViewModelProvider(requireActivity()).get(SharedViewModel::class.java)

// Fragment A sets data
sharedViewModel.someData.value = "Hello from Fragment A"

// Fragment B observes changes
sharedViewModel.someData.observe(viewLifecycleOwner) { data ->
    // Use the received data
}

Thus, the ViewModel acts as a common data source between fragments, simplifying communication and preserving data during configuration changes.
