Linter for Dart #

A Dart style linter.

Installing #

Clone the linter repo like this:

git clone https://github.com/dart-lang/linter.git

When the source is more mature, we’ll push regular builds to pub.

Usage #

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.

Since we are currently in such active development, running from source is the best way to try the linter out.

Running it looks like this:

dart path_to_lint_clone/bin/linter.dart my_project

With example output looking like this:

my_project/my_library.dart 13:8 [lint] DO name non-constant identifiers using lowerCamelCase.
  IOSink std_err = stderr;

Supported options are

-h, --help            Shows usage information.
-c, --config          Use configuration from this file.
    --dart-sdk        Custom path to a Dart SDK.
-p, --package-root    Custom package root. (Discouraged.) Remove to use package information computed by pub.

Note that you should not need to specify an sdk or package-root. Lint configuration file format is provisional and under active discussion. Other configuration options are on the way.
