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

Question

I am getting this exception when I sign in using google. This exception only comes after the apk is uploaded for internal app sharing. If we manually download this apk then every thing works perfectly fine. This works in debug but not in release.

I have tried the below:

1. Settings in firebase console: SHA-1 fingerprint (debug) SHA-256 fingerprint (debug) SHA-1 fingerprint (release) SHA-256 fingerprint (release)
2. replaced the old google-services.json with the updated one
3. Also filled all the required details in the given URL: https://console.developers.google.com/apis/credentials/consent and it is in review state.
   4. Also I have set the support email in firebase

Below gradle code

signingConfigs {
    release {

            keyAlias 'key'
            keyPassword 'pass'
            storePassword 'pass'
            storeFile file('/Users/xyz/file.keystore')

    }
}
buildTypes {
    release {
        signingConfig signingConfigs.release
        minifyEnabled true
        useProguard true

        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
    debug {
        signingConfig signingConfigs.debug
    }
}
dependencies {
 ...

implementation 'com.google.firebase:firebase-auth:19.0.0'
implementation 'com.google.android.gms:play-services-auth:17.0.0'

}

apply plugin: 'com.google.gms.google-services'

Expected: Successful sign in using google. Actual result: Getting exception:PlatformException(sign_in_failed, com.google.android.gms.common.api.ApiException: 10: , null)
