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 then comment @googlebot I fixed it.. If the bot doesn't comment, it means it doesn't think anything has changed.

Thanks for the submission! We’re currently working through a large backlog of PRs, and this will require non-trivial review, so it will take a little time before we’re able to review it. As explained in CONTRIBUTING.md, votes for the corresponding issue are the primary way we’re prioritizing non-trivial reviews; this is a fairly highly-rated issue, so we expect to get to this soon after completing the in-progress null-safety migrations.

This will need a test of the code in webview_flutter.dart (that it's sent to the interface); ideally there would native testing as well, but we need infrastructure plumbed up for that for webview_flutter still, and I don't think we need to gate this change on that.

We apologize for the long delay in triaging this PR. We’re in the process of overhauling our PR triage system to respond much more quickly, as well as working through the backlog.

Since #3431 is opened and somebody is handling it, it seems that I can take some rest.
I'm closing this merge request. Guys, please follow #3431 instead.
