fetchPrevious method

Future<List<CallLog>> fetchPrevious({ required dynamic onSuccess(List<CallLog> callLogs), required dynamic onError(CometChatCallsException excep), })

Fetches the previous batch of call logs.

The onSuccess function is called with a list of CallLog objects when the call logs are successfully fetched. The onError function is called with a CometChatCallsException object when there is an error while fetching the call logs.

Returns a Future that resolves to a list of CallLog objects.

Example:

fetchPrevious(
  onSuccess: (callLogs) {
    // Process the fetched call logs
  },
  onError: (exception) {
    // Handle the error
  },
);

Implementation

Future<List<CallLog>> fetchPrevious(
    {required Function(List<CallLog> callLogs) onSuccess,
    required Function(CometChatCallsException excep) onError}) async {
  if (!await CometChatCalls.isInitialized()) {
    onError(CometChatCallsException(
        CometChatCallsConstants.codeCometChatCallsSDKInitError,
        CometChatCallsConstants.messageCometChatCallsSDKInit,
        CometChatCallsConstants.messageCometChatCallsSDKInit));
  } else if (authToken == null) {
    onError(CometChatCallsException(
        CometChatCallsConstants.codeUserAuthTokenNull,
        CometChatCallsConstants.messageCodeUserAuthTokenNull,
        CometChatCallsConstants.messageCodeUserAuthTokenNull));
  } else if (authToken!.isEmpty) {
    onError(CometChatCallsException(
        CometChatCallsConstants.codeUserAuthTokenNull,
        CometChatCallsConstants.messageCodeUserAuthTokenBlankOrEmpty,
        CometChatCallsConstants.messageCodeUserAuthTokenBlankOrEmpty));
  }
  if (currentPage == 1) {
    onSuccess(<CallLog>[]);
    return [];
  }
  ApiConnection().getCallLogList(getParams(false), authToken!,
      (String response) {
    getCallLogList(onSuccess, onError, response);
  }, (CometChatCallsException e) {
    CometChatCallsUtils.showLog(_tag, "generateToken onError: ${e.message}");
    onError(e);
  });
  return [];
