Description
Thank you for taking the time to file an issue!

- Dart core libraries ("dart:async", "dart:io", etc.)
- Dart VM
- dart2js
- dev_compiler
I followed the instructions on https://dart.dev/tutorials/web/get-started, https://dart.dev/web/debugging. And when I opened the configured chrome devtools, refresh the page. Then the console log the following warnings.
