DO Use Flutter TODO format.
From the Flutter docs:
TODOs should include the string TODO in all caps, followed by the GitHub username of the person with the best context about the problem referenced by the TODO in parenthesis. A TODO is not a commitment that the person referenced will fix the problem, it is intended to be the person with enough context to explain the problem. Thus, when you create a TODO, it is almost always your username that is given.
// TODO(username): message. // TODO(username): message, https://URL-to-issue.
