Implementation

static Future<Map<String?, String?>?> addMembersToGroup(
    {required String guid,
    required List<GroupMember> groupMembers,
    required Function(Map<String?, String?> result)? onSuccess,
    required Function(CometChatException excep)? onError}) async {
  try {
    // Get SDK instance
    final sdk = SdkRegistry.getInstance();

    // Call repository
    await sdk.groupMembers.addMembers(guid, groupMembers);

    // Create success map (matching Android SDK behavior)
    final res = <String?, String?>{};
    for (final member in groupMembers) {
      res[member.uid] = 'success';
    }

    // Call success callback
    if (onSuccess != null) onSuccess(res);
    return res;
  } on SdkException catch (sdkEx) {
    // Convert SdkException to CometChatException
    final cometChatEx = CometChatException(
      sdkEx.code,
      sdkEx.details ?? sdkEx.message,
      sdkEx.message,
    );
    _errorCallbackHandler(cometChatEx, null, null, onError);
  } catch (e) {
    // Handle unexpected errors
    _errorCallbackHandler(null, null, e, onError);
  }
  return null;
