🐛 [FirebaseCore] iOS App Initialization Crashing - Attempting an Android App?

[bretmh]

Bug report

Describe the bug
When using the following API to initialize my DEFAULT app I get a runtime expectation for using an incorrect GOOGLE_APP_ID in my GoogleService-Info.plist. I've added some prints to the library code and it's attempting to initialize two firebase apps.

The first app is my ios Firebase App, which seems to be fine.

Right after, it's trying to initialize an android app as well which is where the error occurs.

If you are using the plist file, use the iOS version of bundle identifier to download the file, and do not manually edit the GOOGLE_APP_ID. You may change your app's bundle identifier to 'com.myapp.ios'. Or you can download a new configuration file that matches your bundle identifier from https://console.firebase.google.com/ and replace the current one.

This seemed to begin happening around the time of using the flutterfire cli to configure and initialize using a generated firebase options class. I've added and removed the plist file many times and

Steps to reproduce

Steps to reproduce the behavior:
I do not have reproducible steps. It might be related to the flutterfire cli and possibly choosing the wrong firebase app at one point.

Expected behavior

Initialization as usual

Sample project

No new app seems to be doing this

---

Additional context

There is a single GoogleService-Info.plist in my Runner folder. I'm really unsure of how it could be seeing any android configuration options.

I've now tried to recreate my app with a fresh flutter create. Copied my lib, assets and pubspec.yaml over.

Following steps were taken:
0. Setup my bundle identifier(ios - Runner.xcworkspace) and applicationId (android - android/app/build.gradle).

1. flutterfire configure. This did not resolve the existing ios (bundle identifier) from step 0. fluttefire decided to register it's own ios app to my firebase project?
2. Ran initialize app with the currentPlatform options.
3. Failed with the OP errors
4. Removed the generated options file
5. Added the GoogleService-Info.plist file from the correct app
6. Failed again with the same error

So, it's reproducible with the steps above.

1. create a flutter project
2. add the dependencies to initialize an app
3. create a firebase project and add an ios app
4. edit the bundle identifier to the correct one you need
5. flutterfire configure for ios
6. it will not resolve the correct app and try to register a new one

Since this issue involves using flutterfire CLI and this behavior seems to be happening due to it, this issue need to be opened in CLI's dedicated repo: https://github.com/invertase/flutterfire_cli/issues

https://firebase.flutter.dev/docs/cli/#reporting-an-issue
Closing from here. If you disagree, or think this is also happening without using the CLI tool, write in comments and I'll reopen it.
Thanks.

Personally, I don't think this is a flutterfire cli only issue. Yes, I am using their tool as explained in their documentation. Although, Firebase is trying to configure itself without me telling it to and with the wrong options.

I agree. Please reopen. I set a breakpoint in main and it isn't hit.

Could we re-open this? I've removed the CLI tool and am still experiencing this issue.

The CLI developers have mentioned this does not look like a problem on their end.

I don't know that I've ever used the flutterfire CLI. This was an existing flutter project. Can you explain why this is supposedly related to the flutterfire CLI?
