For anyone tries to develop react native with expo first time after me:

• Read this doc: https://rnfirebase.io/#expo-managed-workflow (there is a section about "expo-build-properties" and you need to install it)
• After that, if you didn't enable Google sign-in, you will got another error with REVERSE_CLIENT_ID. Follow this page: https://github.com/invertase/react-native-firebase/issues/7338 (remember to add SHA-1 for android too)
