How to fill the spinner with a custom object with coroutines and implement your onItemSelected logic related to that object?

Question

For example, let's use this class:

data class Person (
    var id : Long,
    var name: String,
    var imageUrl: String
)

I need to fill my spinner with name values from the custom objects of Person, and when some value is selected in spinner, I need to update the image according to the imageUrl in the selected object.

Is there any other way to make that than overriding toString() function in Person? For example, if I have to use Person class somewhere else where I need another toString implementation

Also I'm getting the List of Persons from api/room through kotlin coroutines

private fun collectFlows(){
        lifecycleScope.launchWhenStarted {
            repeatOnLifecycle(Lifecycle.State.STARTED){
                mainViewModel.personStateFlow.collectLatest {
                    // update adapter's list
                }
            }
        }
    }

so how to always update the list in adapter when it changes? I know how to make it with custom adapter for RecyclerView, but I'm confused about how to make such thing with spinner adapter.
