This egotistical PR aims to draw attention to a [style guideline](https://github.com/flutter/flutter/blob/master/docs/contributing/Style-guide-for-Flutter-repo.md#use--for-getters-and-callbacks-that-just-return-literals-or-switch-expressions) that I changed: > #### Use `=>` for getters and callbacks that just return literals or switch expressions <br> There was an opportunity for valuable discussion in #154753 about how this structure affects readability, but I shut it down pretty quick since there was a lot of other stuff going on there. Interested to hear thoughts from @Piinks and others.
