How to deconstruct map to list?
I have a List that contain country, I used groupBy to group them by country and now i would like to get fallowing result (for recycled view):
Country1
Airport1
Airport2
Airport3
Country2
Airport4
Airport5
Airport6

could someone give me a tip on how to do this?
My data class:
data class Airport(
val city: City,
val code: String,
val country: Country,
val name: String,

)
