List<E>.unmodifiable constructor
- Iterable elements
Creates an unmodifiable list containing all elements
.
The Iterator of elements
provides the order of the elements.
An unmodifiable list cannot have its length or elements changed. If the elements are themselves immutable, then the resulting list is also immutable.
final numbers = <int>[1, 2, 3];
final unmodifiableList = List.unmodifiable(numbers); // [1, 2, 3]
unmodifiableList[1] = 87; // Throws.
Implementation
external factory List.unmodifiable(Iterable elements);
