@nickstamp93 in new version of navigation you can pass data back to your previous destination this feature added in 2.3.0-alpha03 you can send data from destination B like this: navController.previousBackStackEntry?.savedStateHandle?.set("key", result) and get data in destination A like this:

    navController.currentBackStackEntry?.savedStateHandle?.getLiveData("key")?.observe(
        viewLifecycleOwner) { result ->
        // Do something with the result.
    }
