Thanks for the contribution. In general it seems fine, just one minor thing

This was a recent change to the Firebase C++ SDK, so you might just be out of date on that. https://github.com/firebase/firebase-cpp-sdk/pull/1217/files#diff-fa379ca24a0012efe3cc69026f1be97dcba3f5883f45c26cb5314f4b2c3190ee

I see, we need to update subrepo too

But then, are there anyway we could also update subrepo along with the main repo automatically?
