Small helper to keep track of Flutter Create requirements. Basically, it yells at you if your Dart code is more than 5KB.
Shows tiny image in status bar indicating amount of bytes your *.dart files are occupying.
Thumbs up if you fit into 5KB Thumbs down otherwise.
Per official rules, unit test that are not executed are not counted towards limit. Honestly, I don't know any good reason not to delete it then.
