Excellent video Johan!!! I have struggled with collections in Dart when using a course on Udemy, however, this explanation just makes perfect sense, you need to develop a course and sell on Udemy :-) Thank you so much!

Cool. I've got a question, a confusion actually that I want to clear. I studied List under Dart data type from one source and Collection List from another source after a while so I'm confused now if they're the same thing or there's some difference. I mean Data Type List & Collection List, Is it the same thing?
@JohanJurrius
@JohanJurrius 2 года назад
Yes, same thing. Collections are collections of related data. Lists, Sets and Maps are examples. List, Set and Map are also data types to declare a variable as a List for example. So in List cars = ["Ford", "Honda",...]; cars is a List that contains a collection of String values (cars).

How to replace list item in final ??while integar value is not allowed in final
@JohanJurrius
@JohanJurrius 2 года назад
Pls give me more info on what you want to do. If something is declared final, you cannot change it / replace list item. Not possible.

var newList = [0, '1', '2', '3']; //newList newList.insert(4, 4); //can add if list is object var list2 = ['1', '2', '3']; //list2 list2.insert(0, 0); //will error if list is not string

how can I replace an item in a list with another item in the same index? (ie delete an item and place another item in the same place as it was)

listName[indexOfOldItem] = newItem;
