# removeWhere method

void removeWhere(

1. bool test(
   1. E value
   )

)
override

Removes all elements of this set that satisfy `test`.

    final characters = <String>{'A', 'B', 'C'};
    characters.removeWhere((element) => element.startsWith('B'));
    print(characters); // {A, C}

## Implementation

    void removeWhere(bool test(E element)) {
      List<Object?> toRemove = [];
      for (E element in this) {
        if (test(element)) toRemove.add(element);
      }
      removeAll(toRemove);
    }
