If a set literal is of type set then what is its class in dart?

Question

So the following code snippet

Set mySet = {1,2,3};

is an instance of type Set which is permissible, however what would the class of the set literal be. I have tried to search for this, however I have found no answer in the dart documentation.

Answer 1

A literal exists only in your source code. Asking for its "class" doesn't make a lot of sense.

Using a Set , Map , or List literal is just syntactic sugar for invoking a corresponding constructor. The Set factory constructor constructs a LinkedHashSet .

However, you'll see that LinkedHashSet is also abstract. Its factory constructor returns an instance of a private, internal class. You can see its typename via print(Set().runtimeType) ; the actual type might be different for different platforms and is unlikely to be useful to you.
