@override bool remove(Object? value)

Returns true if value was in the set, and false if not. The method has no effect if value was not in the set.

final characters = <String>{'A', 'B', 'C'};
final didRemoveB = characters.remove('B'); // true
final didRemoveD = characters.remove('D'); // false
print(characters); // {A, C}

Implementation

@override
bool remove(Object? value) {
  final bool hasRemoved = this.value.remove(value);
  if (hasRemoved) {
    refresh();
  }
  return hasRemoved;
}
