Code Review

This pull request correctly refactors error reporting on the web to use console.error() instead of console.log. This is achieved by introducing a platform-specific ErrorToConsoleDumper using conditional imports, which is a solid approach. The related test utilities have also been updated to accommodate this change. My review includes a couple of suggestions to improve code consistency and adherence to the style guide.

This pull request executed golden file tests, but it has not been updated in a while (20+ days). Test results from Gold expire after as many days, so this pull request will need to be updated with a fresh commit in order to get results from Gold.

For more guidance, visit Writing a golden file test for package:flutter.

Reviewers: Read the Tree Hygiene page and make sure this patch meets those guidelines before LGTMing.

Should nothing in foundation be using debugPrint now? If so ideally we could have a lint for that, otherwise maybe just document it somewhere.

Should nothing in foundation be using debugPrint now? If so ideally we could have a lint for that, otherwise maybe just document it somewhere.

Using debugPrint is fine. But to capture errors on the web, one needs to also listen to ErrorToConsoleDumper in addition to debugPrint. I added a breadcrumb that points to ErrorToConsoleDumper in the docs of debugPrint.
