why allow nullptr by default if it throws if nullptr?

if (textedit != nullptr) {
qtextedit = textedit;
} else {
throw spdlog_ex("Error opening QTextEdit");
}
}

~qtextedit_sink() { flush_(); }

can never be null. why check it?

if(qtextedit == nullptr)
return;
memory_buf_t formatted;
base_sink<Mutex>::formatter_->format(msg, formatted);
string_view_t str = string_view_t(formatted.data(), formatted.size());
