Project line length to 120

[FMorschel]

Hey!
As of Dart 3.7.0, we can now set the line width project wise.

If you want to be sure every place Dart formatter is present that it will consider the length, here is how you do it: dart-lang/dart_style#918 (comment)

Edit: first time opening an issue on my phone so I messed up the title 😅

Hey @FMorschel
This would mean increasing the environment constraints which wouldn’t be necessary right away.
