remove method
Removes the first occurrence of item
from this IList.
IList<String> parts = ["head", "shoulders", "knees", "toes"].lock;
parts.remove("head");
parts.join(", "); // "shoulders, knees, toes"
The method has no effect if item
was not in the list.
Implementation
IList<T> remove(T item) {
final L<T> result = _l.remove(item);
return identical(result, _l) ? this : IList<T>._unsafe(result, config: config);
}
