This tracker is for issues related to:

• Dart analyzer and linter - Yes related to linter 80 is very very small its creates a lot of screen empty space in middle of screens,
  120 or 140 is what that is required to be needed instead of 80. Can we update to 120 or 140 or have linter that supports 120 or 140.
