this integration test is cursed :) I triggered a re-run of the job.

[LukeMoody01]

I am not too sure why the callback test is failing in the job. I have tested it a lot locally, even creating new emulators to test on and it seems to work every time.

Any suggestions here would be great 🙂 (As I don't want to bombard the CI workflow by constantly pushing)

FYI @miquelbeltran

Hey! Due to changes in our contributor guidelines, all PRs should now:

• Have a title that follows the Conventional Commits format. e.g. feat(package_name)!: feature description
• DO NOT modify the CHANGELOG.md or the version in the pubspec.yaml. This is going to be an automated process now.

We would ask you kindly to update the PR following these changes.

Thanks!

The test definitely works locally but fails on CI. I think we can merge this, skip the test, and maybe someday go back to it.

Merged, thanks for the work @LukeMoody01 !
