Instructions on releasing Webdev

• Make sure you are on the Dart stable SDK version (check with dart --version)
• Update the DWDS version in /webdev/pubspec.yaml to match the newly released DWDS version, and update the Webdev version to the new version number. Also, comment out the dependency_override so that Webdev is now depending on the version of DWDS on pub (which should have just been published) instead of the local version.
• Update /webdev/CHANGELOG.md to match the new webdev version
• From /webdev, run dart pub upgrade
• From /webdev run dart run build_runner build, this will build and update the version in webdev/lib/src/version.dart
• Before submitting your PR, test that everything is working by following instructions in the webdev/example README to run the example app and connect to Dart DevTools.
• Submit a PR with those changes (example PR: https://github.com/dart-lang/webdev/pull/1498)
• Once the PR is submitted, pull from master and run dart pub publish
• Finally, go to https://github.com/dart-lang/webdev/releases and create a new release, eg https://github.com/dart-lang/webdev/releases/tag/webdev-v2.7.8. You might need to delete some of the content of the autogenerated notes.
