Description

After upgrading Firebase Core from version 2.27.0 to version 2.30.1, running the build runner resulted in the following error in the log output.

The error originates from the _flutterfire_internals package v1.3.32. Downgrading the package to v1.3.31 by overriding it, resolved the error. It's noted that the error was addressed in a merged pull request: PR #12698, which was released in version 1.3.32.

Expected Behavior

The build runner should execute without errors.

Current Behavior

The build runner fails with the reported error.

Reproducing the issue

Upgrade Firebase Core to version 2.30.1. Using the latest build_runner: ^2.4.9 Run the build runner dart run build_runner build --delete-conflicting-outputs

Firebase Core version

2.30.1

Flutter Version

3.19.6

Thanks for the report I'm looking into it, have you tried to exclude this particular file in your build.yaml file?

[Lyokone]

I cannot reproduce the issue, could you give a complete sample?

hello @Lyokone ,

my comment not related to mentioned issue, but if I can please ask to do another version release to include 10.11.1 firebase js library https://firebase.google.com/support/release-notes/js to resolve following issue https://github.com/firebase/firebase-js-sdk/pull/8145 which is long running annoying problem for my flutter app, please help 🙏

@Lyokone pinning 2.30.0 solves it.

  firebase_core: 2.30.0
  firebase_messaging: ^14.8.0

I ran into this too. Updating to the latest versions of all the Flutter Firebase packages solved the error for me.

For some reason, updating to the latest Firebase packages worked earlier, but now I'm getting the same error again, even with all the latest packages.

Pinning _flutterfire_internals to 1.3.31 solves the error for me.

Hey @isaacadariku. We need more information to resolve this issue but there hasn't been an update in 7 weekdays. I'm marking the issue as stale and if there are no new updates in the next 7 days I will close it automatically.

If you have more information that will help us get to the bottom of this, just add a comment!

[ciprig]

The issue still happen with firebase_core: 2.31.0

@Lyokone Thanks for the response. I have not tried excluding the file in the build.yaml file. Can you provide an example of excluding the file in the build.yaml file? As this file is part of the _flutterfire_internals package, I am not sure how to exclude it.

I will try to create a sample project to reproduce the issue and share it with you.
