A Dart style linter.
The easiest way to install the linter is to globally activate it via pub:
$ pub global activate linter
Alternatively, clone the linter repo like this:
$ git clone https://github.com/dart-lang/linter.git
Linter for Dart gives you feedback to help you keep your code in line with the published Dart Style Guide. Currently enforced lint rules (or "lints") are catalogued here. When you run the linter all lints are enabled but don't worry, configuration, wherein you can specifically enable/disable lints, is in the works. While initial focus is on style lints, other lints that catch common programming errors are certainly of interest. If you have ideas, please file a feature request.
Running the linter via pub looks like this:
$ pub global run linter my_project
With example output will looking like this:
my_project/my_library.dart 13:8 [lint] Name non-constant identifiers using lowerCamelCase.
IOSink std_err = stderr;
