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

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

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
firebase/firebase-js-sdk#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.
