        // if null pointer will return
        **if (!createParams->lpcs->lpszClass) {

        if (wcscmp(createParams->lpcs->lpszClass, L"FLUTTER_RUNNER_WIN32_WINDOW") == 0)
        {
            flutter_window = (HWND)wparam;
            SetWindowSubclass(flutter_window, main_window_proc, 1, NULL);
        }
