Description

TL;DR: After running flutterfire configure with this parameter and its value --android-out=android/app/firebase/flavors/staging/google-services.json , running the staging version of my app on an Android emulator gives me the following error:

DETAILED DESCRIPTION:

I have a Flutter project configured with two flavours staging and production that are working well for some time for both Android and iOS
I wanted to add a push notification service through FCM, so I created two Firebase projects, one for the staging version of my app, and the other for the production version of my app
I configured Firebase in my Flutter project by running the following flutterfire command:

        flutterfire configure \
            --project=<redacted> \
            --out=lib/firebase/firebase_options_staging.dart \
            --android-package-name=<redacted> \
            --android-out=android/app/firebase/flavors/staging/google-services.json \
            --ios-bundle-id=<redacted> \
            --ios-out=ios/firebase/flavors/staging/GoogleService-Info.plist \
            --ios-build-config=Debug-staging,Profile-staging,Release-staging

        flutterfire configure \
            --project=<redacted> \
            --out=lib/firebase/firebase_options_production.dart \
            --android-package-name=<redacted> \
            --android-out=android/app/firebase/flavors/production/google-services.json \
            --ios-bundle-id=<redacted> \
            --ios-out=ios/firebase/flavors/production/GoogleService-Info.plist \
            --ios-build-config=Debug-production,Profile-production,Release-production

I changed my main.dart file to load the appropriate FirebaseOptions:

// main.dart file
...
void main() async {
...
WidgetsFlutterBinding.ensureInitialized();
await initializeFirebaseApp();
...
}


// flavor_config.dart file

import 'package:flutter/services.dart'; import 'firebase/firebase_options_production.dart' as production; import 'firebase/firebase_options_staging.dart' as staging; import 'package:firebase_core/firebase_core.dart';

enum Flavor { production(envFilePath: 'env/production.env'), staging(envFilePath: 'env/staging.env');

final String envFilePath;

const Flavor({required this.envFilePath}); }

Flavor getFlavor() => switch (appFlavor) { 'production' => Flavor.production, 'staging' => Flavor.staging, _ => throw UnsupportedError( 'Invalid flavor: "$appFlavor". Please specify one of the following flavors: "production", "staging" (flutter run --flavor staging).'), };

Future initializeFirebaseApp() async { final firebaseOptions = switch (getFlavor()) { Flavor.production => production.DefaultFirebaseOptions.currentPlatform, Flavor.staging => staging.DefaultFirebaseOptions.currentPlatform, }; await Firebase.initializeApp(options: firebaseOptions); }

- Running the `flutterfire configure` commands previously mentioned produced the creation of the following `firebase.json` file:
```json

                        "uploadDebugSymbols": false,
                        "fileOutput": "ios/firebase/flavors/production/GoogleService-Info.plist"
                    },
                    "Profile-production": {
                        "projectId": "<redacted>",
                        "appId": "<redacted>",
                        "uploadDebugSymbols": false,
                        "fileOutput": "ios/firebase/flavors/production/GoogleService-Info.plist"
                    },
                    "Release-production": {
                        "projectId": "<redacted>",
                        "appId": "<redacted>",
                        "uploadDebugSymbols": false,
                        "fileOutput": "ios/firebase/flavors/production/GoogleService-Info.plist"
                    }
                }
            },
            "dart": {
                "lib/firebase/firebase_options_staging.dart": {
                    "projectId": "<redacted>",
                    "configurations": {
                        "android": "<redacted>",
                        "ios": "<redacted>",
                        "web": "<redacted>"
                    }
                },
                "lib/firebase/firebase_options_production.dart": {
                    "projectId": "<redacted>",
                    "configurations": {
                        "android": "<redacted>",
                        "ios": "<redacted>",
                        "web": "<redacted>"
                    }
                }
            }
        }
    }
}

So I can see that the --android-out=android/app/firebase/flavors/staging/google-services.json parameter I specified when running the flutterfire command was taken into account as it has it is mentioned in the firebase.json file.

When I try to run the staging version of my app on an Android emulator, it fails and I get the following error printed:
```
FAILURE: Build failed with an exception.
```
What went wrong: Execution failed for task ':app:processStagingDebugGoogleServices'.

### Steps to reproduce

1. Have a Flutter project configured with flavours (`staging`, `production`) (this step may be optional, but I cannot say for sure, see *"Hypothetical short steps to reproduce"* section below)
2. Have a Firebase project for the `staging` and `production` versions of the Flutter app (you could only do this for the `staging` version to avoid duplicating the work, in this case, remove all the further tasks related to the `production` version of the app)
3. Configure Firebase in the Flutter project for the `staging` and `production` versions of the app:
```shell
        flutterfire configure \
            --project=<redacted> \
            --out=lib/firebase/firebase_options_staging.dart \
            --android-package-name=<redacted> \
            --android-out=android/app/firebase/flavors/staging/google-services.json \
            --ios-bundle-id=<redacted> \
            --ios-out=ios/firebase/flavors/staging/GoogleService-Info.plist \
            --ios-build-config=Debug-staging,Profile-staging,Release-staging

        flutterfire configure \
            --project=<redacted> \
            --out=lib/firebase/firebase_options_production.dart \
            --android-package-name=<redacted> \
            --android-out=android/app/firebase/flavors/production/google-services.json \
            --ios-bundle-id=<redacted> \
            --ios-out=ios/firebase/flavors/production/GoogleService-Info.plist \
            --ios-build-config=Debug-production,Profile-production,Release-production

Change main.dart and add a flavor_config.dart file like so:

// main.dart file
...
void main() async {
...
WidgetsFlutterBinding.ensureInitialized();
await initializeFirebaseApp();
...
}


// flavor_config.dart file

enum Flavor { production, staging }

Flavor getFlavor() => switch (appFlavor) { // This appFlavor variable comes from package:flutter/services.dart 'production' => Flavor.production, 'staging' => Flavor.staging, _ => throw UnsupportedError( 'Invalid flavor: "$appFlavor". Please specify one of the following flavors: "production", "staging" (flutter run --flavor staging).'), };

5. Add `firebase_core` to your project: `flutter pub add firebase_core` (I have version `3.1.0`)
6. Run the staging version of the app on an Android simulator: `flutter run --flavor staging`
7. Notice the run failure and the output log in the console:

FAILURE: Build failed with an exception.

**"Hypothetical short steps to reproduce"**
Flavours may not be required to reproduce this if specifying a location for `google-services.json` file, via the `--android-out` parameter of the `flutterfire command`, is enough to notice if the Gradle task `:app:process(Staging)DebugGoogleServices` does not look for the `google-services.json` file in the location we specified

---

### Expected behavior

When running the staging version of my app on an Android emulator, I expected the `google-services.json` file to be found at the location I specified.

Path I specified:

android/app/firebase/flavors/staging/google-services.json


Path where it was searched for:

Execution failed for task ':app:processStagingDebugGoogleServices'.

File google-services.json is missing. The Google Services Plugin cannot function without it.
