I'm offering a free, virtual code review for all #dart code!(1) Scan your diff for new fields on classes
(2) Play my voice in your mind's ear: "Could that be final?"That's it!
There's even a lint. It won't catch all cases, but it's a good start: https://dart-lang.github.io/linter/lints/prefer_final_fields.html
