removeWhere method

@override void removeWhere(bool test(T element))

Removes all objects from this list that satisfy test.

An object o satisfies test if test(o) is true.

final numbers = <String>['one', 'two', 'three', 'four'];
numbers.removeWhere((item) => item.length == 3);
print(numbers); // [three, four]

The list must be growable.

Implementation

@override
void removeWhere(bool Function(T element) test) {
  _context.conditionallyRunInAction(() {
    final removedElements = Queue<ElementChange<T>>();
    for (var i = _list.length - 1; i >= 0; --i) {
      final element = _list[i];
      if (test(element)) {
        removedElements.addFirst(
          ElementChange(
            index: i,
            oldValue: element,
            type: OperationType.remove,
          ),
        );
        _list.removeAt(i);
      }
    }
    if (removedElements.isNotEmpty) {
      _notifyElementsUpdate(removedElements.toList(growable: false));
    }
  }, _atom);
}
