removeAt method

  1. @override
E removeAt(
  1. int index
)
override

Removes the object at position index from this list.

This method reduces the length of this by one and moves all later objects down by one position.

Returns the removed value.

The index must be in the range 0 ≤ index < length. The list must be growable.

final parts = <String>['head', 'shoulder', 'knees', 'toes'];
final retVal = parts.removeAt(2); // knees
print(parts); // [head, shoulder, toes]

Implementation

@override
E removeAt(int index) {
  E element = _values.removeAt(index);
  // Stop listening to child
  if (_propagateNotification && element != null && element is ChangeNotifier)
    element.removeListener(_propagate);

  notifyListeners();
  return element;
}
