fetchPrevious method

Future<List<CallLog>> fetchPrevious(
  1. {required dynamic onSuccess(
    1. List<CallLog> callLogs
    ),
  2. required dynamic onError(
    1. 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 [];
}
