Set<E>.unmodifiable constructor Null safety

Set<E>.unmodifiable(
  1. Iterable<E> elements
)

Creates an unmodifiable Set from elements.

The new set behaves like the result of Set.of, except that the set returned by this constructor is not modifiable.

Implementation

factory Set.unmodifiable(Iterable<E> elements) =>
    UnmodifiableSetView<E>(<E>{...elements});
