Flutter and google_sign_in plugin: PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null)

Question

The dialog (Google form) for the credentials is opened successfully, but after I fill my credentials I'm getting this error. I followed the instructions from here. Created a Firebase project, enabled the Google Drive API (that's what I need for now) from the Google APIs Console.

The code throwing the exception:

final GoogleSignIn _googleSignIn = GoogleSignIn(
  scopes: [
    'https://www.googleapis.com/auth/drive',
  ],
);
await _googleSignIn.signIn();

That's the stack trace:

E/flutter ( 5068): [ERROR:flutter/shell/common/shell.cc(184)] Dart Error: Unhandled exception:

The version of the google_sign_in plugin is 4.0.0.

That's the output of flutter doctot -v:

Any help will be much appreciated. Thanks!

Solution 1

I run into the same issue just now. This might happens if you are running on debug and you did not register a SHA fingerprint in firebase. I solved it by generating a debug.keystore and registering it inside the app on Firebase. Don't forget to download the new google-services.json after that. See also this.

Edit If you are not able to use authenticate in release mode try the following:

-Add the SHA certificate fingerprints of the release key.

keytool -exportcert -list -v \ -alias <your-key-name> -keystore <path-to-production-keystore>

For more details on that see here on the section "get release certificate" https://developers.google.com/android/guides/client-auth

If your authentication is still not working, probably it is because you downloaded the app from Playstore and you enabled the "App Signing by Google Play Feature" Then for this case, go to play store publish console and go to app signing under release management. There you will find the SHA certificate fingerprint to register in Firebase console.

Solution 2

The following solution works in flutter project:

Step 1: Generate SHA1 and SHA256 keys.
Step 2: Add both the SHA1 and SHA256 to firebase. (in you app settings)
Step 3: Download google-services.json to android/app in your project folder.
Step 4: In your terminal run the command flutter clean .
Step 5: Run your flutter app.

For more information visit:
https://developers.google.com/android/guides/client-auth
https://firebase.google.com/docs/flutter/setup

Solution 3

I spent ages trying to fix this.

1. Open grade.properties This file is found under: {{YOUR PROJECT}}/android/gradle.properties

2. Add the following argument to 'org.gradle.jvmargs' as shown in the screenshot.

-XX:MaxHeapSize=256m -Xmx256m

3. Right click on 'gradlew' and go to 'Open in Terminal' This file is found under {{YOUR PROJECT}}/android/gradlew

4. Type in the following command.

gradlew signingReport

If did not work first try second command:

./gradlew signingReport

5. Wait for the compilation to finish and your SHA keys should be printed out for you.

Use these keys to authenticate your app in https://console.firebase.google.com/

Solution 4

Open the Firebase console and click on the settings icon.

You will see the list of the apps connected to your Firebase project

For Android

1. Open terminal inside your flutter project
2. cd android
3. ./gradlew signingReport or gradlew signingReport
4. Paste your SHA1 key
5. Download and replace the google-services.json
6. flutter clean

IOS:

1. Configure your Firebase project
2. Select IOS
3. Enter your Bundle ID
4. Download credetials
5. Download and replace GoogleService-info.plist

Add this to your info.plist

<key>CFBundleURLTypes</key>
<array>
    <dict>
        <key>CFBundleTypeRole</key>
        <string>Editor</string>
        <key>CFBundleURLSchemes</key>
        <array>
            <string>**INSERT HERE YOUR RESERVED_CLIENT_ID FROM GoogleService-Info.plist**</string>
        </array>
    </dict>
</array>

When I came across this problem, I tried all other solutions described in this post. None of these worked. Eventually I figured it out: In my situation I had to make sure to have my "support email" set.

Thanks for this. This helped. Worthwhile noting that both the SHA1 and SHA256 keys had to be added for the auth to work

[Michael Nelson]

FYI, I had the same error even after configuring my sha fingerprints. Turns out i also had to add a support email address per github.com/flutter/flutter/issues/25909#issuecomment-4973786‌​19 .

[mkkhedawat]

clean is very important

[Ahmed Albarody]

where do I enable thant?

[Guy]

@AhmedAlbarody In your firebase console - choose authentication and then you need to enable the services you want to use.

[BHuelse]

gradlew signingReport helps me a lot, because I first I just use the wrong keystore. And with that command, you get definitely the right one.

[greybeard]

I find it difficult to follow your answer: can you get help using English (not my 1st language)?

[PRO GRAMMER]

For me that is the only thing that worked, my keytool generated not working SHA-1 / SHA-256

[Tincho825]

If step 4 didn't work, call gradlew like this instead: ./gradlew signingReport

[Mark Rawlingson]

Chiming in to say this is also the only thing that worked for me. Tried everything else and spent days trying to solve the issue before finding this.

[reverie_ss]

this is the easiest method! this should be accepted.

[Steve Rogers]

The best answer. Perfect.

[ishallwin]

Thanks for the comment. I was finally able to resolve it. :)

[user2897738]

Thank you! This is the missing essential step to putting my app in production that had me trial-and-erroring for hours. Other solutions here were only good for building debug versions.

[adrianvintu]

your edit linking to "If you've published your app using Play App Signing, a requirement when using Android App Bundle, you can get your SHA-1 from the Google Play Console on the Release > Setup > App Integrity page" saved me! thank you!

[efesahin]

solved my problem also

[rahulserver]

you saved my day man!

[ege men]

This is the right solution. Additionally, if Firebase package-name and project package-name (path) do not match, you still get this error code:10.

[Moacir Schmidt]

Removed unused fingerprints and update google-services.json solved for me

[Saugat Thapa]

all the above didnt work but this did... thank u so much!

[Miki]

This was helpful man thanks for sharing!

[Saiful Islam]

You just saved my day.

[C.K.]

By explaining the rootcause, it's much easier to find the correct answer, thank you!
