[google_sign_in] Allow initialization from Dart without adding native config files

[pr-Mais]

Description

In the latest release of FlutterFire plugins, initialization of the DEFAULT Firebase App through Dart has been added, omitting the manual installation step, and enabling flutterfire_cli tool to make this step completely automatic.

Unfortunately, if the app is using google_sign_in, it requires developers to add back the manual installation step even though firebase_auth does support Dart-only initialization, as mentioned here.

Proposal

Allowing google_sign_in to initialize from Dart will make it possible for firebase_auth users to completely migrate to use Dart initialization through flutterfire_cli.

Any update on this?

Hey guys any updates? thanks again.

[crisboarna]

Would be amazing to have this complete !

@darshankawar I am bit confused in documentation. Yes it is mentioned in documentation that dart only initialization is not yet supported for google_sign_in, but it works on android but didn't in ios. I don't remember using google-services.json for android too.
I should have mentioned this before here.

Any updates? It's been 3 months already....

Finished migrating to dart-only initialization just to find out I'll have to rollback :(

I've forked it and fixed: https://github.com/mono0926/plugins/tree/fix-flutterfire/packages/google_sign_in/google_sign_in_ios

Can I ask what's keeping this from being reviewed/merged? Does it depend on this one? flutter/plugins#5250

[blaugold]

@loolooii The PR you linked will fix this issue and is in the process of being landed, it just takes a while because it's a multistep process.

[blaugold]

flutter/plugins#5250 has been merged, so GoogleService-Info.plist is no longer required on iOS.

It is still necessary to register CFBundleURLTypes in Info.plist, but that cannot be done at runtime, so google_sign_in cannot help with that.

Thanks for merging the PR. This a very much need addition to entirely migrate to dart only initialisation.

Question:
Can CFBundleURLTypes list all the urls types of different firebase projects? If we could list there all the different revers google ID belonging to different accounts we could also deal with switching flavours dynamically without having to touch configuration files

[blaugold]

Can CFBundleURLTypes list all the urls types of different firebase projects?

I don't see why not. CFBundleURLSchemes is an array which can contain more than one scheme that the app can handle. With a Xcode build script, you could remove all but one scheme in release builds to be safe.
