Implementation

static Future<int?> show({
  required String title,
  String? message,
  required List<CNAlertAction> actions,
  int? preferredActionIndex,
}) async {
  if (actions.isEmpty) {
    throw ArgumentError('Alert must have at least one action');
  }

  if (preferredActionIndex != null &&
      (preferredActionIndex < 0 || preferredActionIndex >= actions.length)) {
    throw ArgumentError('preferredActionIndex out of range');
  }

  try {
    final result = await _channel.invokeMethod<int>('showAlert', {
      'title': title,
      'message': message,
      'actions': actions.map((a) => a.toMap()).toList(),
      'preferredActionIndex': preferredActionIndex,
    });

    // Execute the callback for the selected action
    if (result != null && result >= 0 && result < actions.length) {
      actions[result].onPressed?.call();
    }

    return result;
  } catch (e) {
    print('Error showing alert: $e');
    return null;
  }
}
