dart-sdk/third_party/devtools

This folder contains a pre-built Dart DevTools instance which can be served
as a web application, as well as the package:devtools_server and package:devtools_shared
from the same revision, used to host and launch DevTools from a Dart process.

First, ensure Flutter is installed and on your path (see https://flutter.dev/docs/get-started/install/linux#install-flutter-manually).

With `flutter` on your path, do the following:

- Run ./update.sh <revision> to build DevTools at a given revision and upload it
  to CIPD. The uploaded CIPD entry will be tagged with `revision:<revision>`
- Update DEPS to point to the newly updated DevTools by providing "revision:<revision>"
  as the version entry for "third_party/devtools"

DevTools CIPD packages are located at https://chrome-infra-packages.appspot.com/p/dart/third_party/flutter/devtools/+/.
