Set.unmodifiable constructor - Set - dart:core library (original) (raw)

description

1. @Since("2.12")

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.

final characters = <String>{'A', 'B', 'C'};
final unmodifiableSet = Set.unmodifiable(characters);

Implementation

@Since("2.12")
factory Set.unmodifiable(Iterable<E> elements) =>
    UnmodifiableSetView<E>(<E>{...elements});
