connect method

Future<int> connect(ConnectParams params, { OperationHandler<String>? handler, })

Connects NCEngine and starts accepting session events on success.

Implementation

  ConnectParams params, {
  OperationHandler<String>? handler,
}) async {
  final generation = ++_connectionGeneration;

    if (generation != _connectionGeneration) {
      return;
    }
    final errorCode = error?.code ?? 0;
