UserViewModel with LiveData map transformation

UserViewModel.kt

class UserViewModel() : ViewModel() {   
  
    /**
     * The user
     */
    private var user: LiveData<User>
  
    /**
     * Full name of the user
     */
    private var userFullName: LiveData<String>

    init {
        // Update the full name when user is changed
        userFullName = Transformations.map(user) { user -> "$user.firstName $user.lastName" }
    }

    /**
     * Get the data
     */
    fun getUser() = user
}

Could it be, you wanted a setter for user and a getter for userFullName here?
