remove method

bool remove(
  1. Object? element
)
override

Removes the first occurrence of value from this list.

Returns true if value was in the list, false otherwise. The list must be growable.

final parts = <String>['head', 'shoulders', 'knees', 'toes'];
final retVal = parts.remove('head'); // true
print(parts); // [shoulders, knees, toes]

The method has no effect if value was not in the list.

final parts = <String>['shoulders', 'knees', 'toes'];
// Note: 'head' has already been removed.
final retVal = parts.remove('head'); // false
print(parts); // [shoulders, knees, toes]

Implementation

bool remove(final Object? element) {
  int pos = indexOf(element as E);
  bool hasRemoved = _inner.remove(element);
  if (hasRemoved) {
    _changes.add(ListChange<E>.remove(element, pos));
  }
  return hasRemoved;
}
