Creates a Set that contains all
elements should be instances of
elements iterable itself can have any type, so this constructor can be used to down-cast a
Set, for example as:
Set<SuperType> superSet = ...; Set<SubType> subSet = new Set<SubType>.from(superSet.where((e) => e is SubType));
The created Set is a LinkedHashSet. As such, it considers elements that are equal (using operator ==) to be indistinguishable, and requires them to have a compatible Object.hashCode implementation.
The set is equivalent to one created by
factory Set.from(Iterable elements) = LinkedHashSet<E>.from;
