Steps to reproduce

Steps to reproduce the behavior:

1. Run the example on a Huawei device or with com.google.android.gms disabled
2. Doesn't work

The only relevant dependency should be
firebase_auth 0.18.2

However, if necessary, I can provide the rest as well.

Hmm, I'm not sure we can upgrade the SDKs yet due to other packages needing a rework.

[CiriousJoker]

That's unfortunate, is there any timeline?

Right now, my fallback implementation is kind of wonky and only works for email signup using 3 different dependencies, so it's bound to break at some point lol.

I'd rather avoid forking repos (including this one again) for this if I can.

[Ehesp]

No timelines, since we're not sure if the plan will work. It essentially means removing the BoM versioning from some modules and hoping they work standalone. Not ideal news, but it is a known problem right now.

[Salakar]

@CiriousJoker if you don't use any of the following you should be 'ok':

• AdMob
• Dynamic Links
• Remote Config
• ML Kit
• Performance Monitoring

and can just override the version you're using yourself: https://firebase.flutter.dev/docs/overview#overriding-native-sdk-versions

Try adding that with the latest BoM version, and see what happens, if it build then you should be ok.

[orestesgaolin]

I followed the guide and applied following sdk version in my build.gradle:

rootProject.ext {
  set('FlutterFire', [
    FirebaseSDKVersion: '26.0.0'
  ])
}

I also have following dependencies listed in build.gradle:

dependencies {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'
    implementation 'com.google.firebase:firebase-analytics:18.0.0'
    implementation 'com.google.firebase:firebase-crashlytics:17.2.2'
}

It seems that many things related to Firebase work in my app on Huawei Y7p (Android 10, EMUI 10.1.0) device without GMS.

Quick summary

Plugins used

• firebase_admob: ^0.10.1 (doesn't work)
• firebase_analytics: ^6.1.0
• firebase_auth: ^0.18.2
• firebase_core: ^0.5.1
• firebase_crashlytics: ^0.2.2
• firebase_dynamic_links: ^0.6.1 (seems to not work)
• firebase_messaging: ^7.0.3 (not tested)
• firebase_storage: ^5.0.0 (throws some exceptions but saves the data)
• google_sign_in: ^4.5.6 (doesn't work)

Issues

On launch the Dynamic Links threw an expection:

PlatformException (PlatformException(ApiException, 17: API: DynamicLinks.API is not available on this device. Connection failed with: ConnectionResult{statusCode=SERVICE_INVALID, resolution=null, message=null}, null, null))

When saving file to Firebase Storage following exception was thrown. The file was saved though, and url was available afterwards.

Other

This was tested on current stable on Huawei device without GMS. App is heavily based on Firestore and it works more or less correctly. The main issues for now are:

• lack of dynamic links support
• some exceptions thrown now and then related to missing google services
• lack of Google Sign In support
• lack of AdMob support
• lack of In-app purchase support

Btw, I'm also using revenuecat and it also doesn't work if anyone is interested:

[Salakar]

@orestesgaolin I forgot to mention, this page lists which Firebase products require Google Play services: https://firebase.google.com/docs/android/android-play-services

On React Native Firebase we have an API to check for Play Services availability; https://gist.github.com/Salakar/593a6e2082f3ab19cf80ebf877fb5572 - if you could find a plugin in Flutter that has these apis (or make your own based on the RNFB source) you could do either (or both) of;

a) limit the Firebase services your app uses and your app functionality if no GMS is available
b) make an APK variant for non Play Store devices, e.g. using --dart-define to control the build types.
