I'm not sure why continuous-integration/travis-ci/pr — The Travis CI build failed is failing. I didn't see it in other merge requests.

Is there something else I should fix?

Thanks for contributing!

To keep the plugins repository scalable we should try to not introduce new features without e2e tests.
The plugins e2e test harness was just recently introduced, and the first e2e test for the connectivity plugin wasn't written yet, I filed flutter/flutter#30210 to setup e2e testing for connectivity, and I think we should wait for that(or alternatively have this PR add the first connectivity feature that's tested e2e). See: https://github.com/flutter/plugins/tree/master/packages/cloud_firestore/example/test_driver for what the e2e tests might look like.

I'm marking this PR as waiting for test harness.

Thank you for providing this PR. The changes look good. We require any new features added to the plugin to have test driver tests. I have created a PR to set up test driver on this plugin. https://github.com/flutter/plugins/pull/1455/files
Could you wait until the PR landed and adding a test for your change? If you don't have time to continue working on this, we can shepherd it from here.
For more details on test driver test, you can refer to https://flutter.dev/docs/cookbook/testing/integration/introduction and our contribution guide here https://github.com/flutter/plugins/blob/master/CONTRIBUTING.md

We found a Contributor License Agreement for you (the sender of this pull request), but were unable to find agreements for all the commit author(s) or Co-authors. If you authored these, maybe you used a different email address in the git commits than was used to sign the CLA (login here to double check)? If these were authored by someone else, then they will need to sign a CLA as well, and confirm that they're okay with these being contributed to Google.
In order to pass this check, please resolve this problem and have the pull request author add another comment and the bot will run again. If the bot doesn't comment, it means it doesn't think anything has changed.

I can resolve the conflicts and add the driver tests this week (though not sure which day).

@cyanglaz I added tests and resolved conflicts, can I get your lgtm to merge this?

[cyanglaz]

LGTM. Just one little thing in the test code.
