There's a check-list item in plugin repo asks contributors to check "I read and followed the Flutter Style Guide and the C++, Objective-C, Java style guides." (https://github.com/flutter/plugins/blame/master/.github/PULL_REQUEST_TEMPLATE.md#L11)

However, the Flutter Style Guide explicitly say the flutter repo does not use dart formatter (https://github.com/flutter/flutter/wiki/Style-guide-for-Flutter-repo#formatting)

This caused some confusions.

We should also not remove this line, because most of the guidelines in Flutter Style Guide are still true for the plugin repo.

Maybe we should update Flutter Style Guide to state the plugin repo does use dart formatter.
