问题
I'm building a Flutter app with firebase_auth and google_sign_in.
Everything was working well for a while and all of my existing users on the released product have not experienced any problems, but a while back I started getting reports that new users couldn't log in. I didn't think much of it until the reports started to accumulate. I found that they were getting the error posted in the title. I spent a ton of time investigating...
I've gone through all of the other StackOverflow entries for this issue:
- Unhandled Exception: PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null)
- PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null)
- Exception has occurred. PlatformException (PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null))

- Error with Google_sign_in plugin in flutter
And I've tried all of the solutions:
- Generated debug key
- Entered SHA1 debug key on the Firebase site
- Verified that my email was entered on the Firebase site.
- Downloaded the google-services.json file and put it in the
android/app/directory - Built the flutter app using
flutter build appbundle --debug - PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null)
So I also tried:
- With just the release key on the Firebase site and built with
flutter build appbundle --release - With both the release key and the debug key
- With the SHA256 for each combination above
With each of these combinations, I was sure to
flutter cleanand replace the google-services.json file with the updated oneVerified that
android/build.gradleandandroid/app/build.gradlewere configured properly- Verified that "Google" was enabled as a "Sign-in Method" was enabled on the Firebase site
- I even filled out the OAuth consent screen with my app name, logo, email, homepage, privacy, & terms of service links and saved
Here are the versions that I'm running with:
google_sign_in: ^4.0.7
firebase_auth: ^0.14.0+5

All testing was done on multiple devices using the Robo test lab on Firebase (only to see if the login was successful, not to test the UI).
TLDR;
In the end, I finally figured out that it works if I build the apk using flutter build apk (as opposed to an appbundle). Then I realized that the problem started about the same time that flutter started recommending that I generate appbundles instead of apks.
Has anyone been able to sign in a BRAND NEW USER with flutter using google_sign_in when generating an appbundle? (Keep in mind that existing users who previously signed in to an earlier version of the app work without issue.)
回答1:
If you are using Internal App Sharing to test Flutter builds on actual Android devices (like I am), there is another App Signing certificate fingerprint you need to add.
On the left navigation of Google Play Console go to: Developer Tools -> Internal App Sharing
Select the App Certificate tab. Should look something like this:
Google Play - Internal App Sharing - Certificate
Copy the SHA1 key and add it to the Firebase Console -> Project Settings -> [your Android app] -> SHA certificate fingerprints (use the button to Add fingerprint)
Download your updated google-services.json and update/add it in your android/app folder of your project.
This works with new users and existing users. I built the an appbundle (not APK) using flutter build appbundle
This isn't documented anywhere by Google and I have not seen this solution elsewhere in the Flutter community. I came across this solution while poking around in the Google Play console after trying all of your referenced links and several others.
