Vito Rizki Imanda No, it's totally okay. I should have uploaded the repo and attached a link from start. Sorry about that. I will do that as soon as I get some time.
Hey Vito Rizki Imanda, I updated the blog and added demo repo. Check it out. Firebase official documentation is misleading. Invites are deprecated but you have to add it to work with react-native-firebase@5.x.x. I forgot to mention this earlier.
