[FR]: Why require google-services.json, if possible without it?

[maxgmer]

Description

Right now it's pain in the butt to enable one project to work with multiple Firebase environments.

To avoid doing stupid stuff like creating/deleting google-services.json files with pre-build scripts, we just use the AppOptions constructor and manually provide all of the data google-services.json contains.
But iOS has annoying errors about plist missing, which forces us to keep google-services.json mock files for iOS and Android (with fake credentials).

Considering how non-optimal the file configuration UX is, why not make it optional?

P.S.If AppOptions is incomplete, would be great if you make it a complete alternative to config files.
