Flutterfire: 🐛 [cloud_firestore] When a user is logged in with google and I'm on release mode I can't create documents in firestore. There are no errors thrown

[davidsebastianfp]

Bug report

Describe the bug
When the user signs in with google in my flutter app it signs in successfully, I can see it the console's authentication page. After signing in I search the document with the user's data in firestore, if it is a new user the method returns null and creates a new document with the data. It works fine when I'm working in debug mode but when I'm in release mode the document for new users isn't created in firestore and it doesn't throw any error.

Everything works as it would when I'm in debug mode with the debug SHA certificate. But when I'm in release mode with the release SHA certificate, the user is created in the console's authentication page, but the document in firestore with the user's data isn't created. I've attached a pdf with the code

Steps to reproduce

Steps to reproduce the behavior:

1. Sign in with google in the firebase project
2. await for the credentials
3. with the uid from firebase search for the doc with the user's data
4. As the user is new it'll return null
5. if the data returned is null create a doc with the user's firebase uid as its id
6. assert that the data is set to firestore

Expected behavior

I would spect the doc gets created with the uid as its id in the collection in firestore, however it isn't created.

Hi @davidsebastianfp
Can you please provide a minimal complete reproducible code sample
Thank you

[davidsebastianfp]

Hi @TahaTesser in this link is a project that reproduces the error

Hi @davidsebastianfp
Thanks for providing a code sample, it does create firestore docs in debug mode but the app is stuck on this screen in release mode and firestore docs are not created. Is this the same behaviour experiencing?

Hi @TahaTesser yes it is the behavior I'm experiencing. It gets stuck because the app is waiting the document to be created but for some reason it is not. As you see in debug mode the doc is created and the app continues normally

[davidsebastianfp]

Hello @TahaTesser , do you have any updates about this?

[Adarsh0603]

Does the Google's Authentication Screen comes up in release mode?

[davidsebastianfp]

@Adarsh0603 yes it does, in fact I log in but i can't create a doc in firestore

[Adarsh0603]

Did you downloaded the googleservices.json file again with the release sha1 key in firebase...
In your firebase project settings you have to update the SHA certificated fingerprints with the release SHA 1 key
and redownload the googleservices.json and add it to your app.

[davidsebastianfp]

@Adarsh0603 Yes I did, that is why I can log in. When I try to use the the debug key an error is thrown

[davidsebastianfp]

@Adarsh0603 so what sould I do. Is anybody trying to fix this error?

[Adarsh0603]

@davidsebastianfp okay it worked...actually the problem is with the assert statements...
the assertions only work in debug mode and are disabled in release mode.

You can read more about it here (https://flutter.dev/docs/testing/build-modes).
You need to call the functions without the assert statements..
