Lint for Dart/Flutter #
lint is a hand-picked, open-source, community-driven collection of lint rules for Dart and Flutter projects.
The set of rules follows the Effective Dart: Style Guide.
This package can be used as a replacement for
package:lints or the discontinued
package:pedantic for those who prefer stricter rules.
lint supports 3 different set of rules:
strict: tries to be strict but not annoying. Perfect for production app code
casual: great when prototyping, to be used in code samples, any non-production code
strictbut for dart packages, that have a public API
lint as dependency to your
^1.0.0 means you're automatically getting the latest version for
lint when running
dev_dependencies: lint: ^2.0.0
analysis_options.yaml file in the root of your project with the following content:
# This file configures the analyzer to use the lint rule set from `package:lint` include: package:lint/strict.yaml # For production apps # include: package:lint/casual.yaml # For code samples, hackathons and other non-production code # include: package:lint/package.yaml # Use this for packages with public API # You might want to exclude auto-generated files from dart analysis analyzer: exclude: #- '**.freezed.dart' #- '**.g.dart' # You can customize the lint rules set to your own liking. A list of all rules # can be found at https://dart-lang.github.io/linter/lints/options/options.html linter: rules: # Util classes are awesome! # avoid_classes_with_only_static_members: false # Make constructors the first thing in every class # sort_constructors_first: true # Choose wisely, but you don't have to # prefer_double_quotes: true # prefer_single_quotes: true
Lint badge #
You're using lint in your open-source project?
Add the badge to your
README.md show that you honor strict lint rules
Comparison with other lint packages #
A detailed comparison of all linting packages for dart can be found at https://rydmike.com/blog_flutter_linting.html
lint is among the strictest but not the strictest. It tires to find the right balance between useful and annoying.
Which version to use? #
Generally, you can just put
lint: ^2.0.0 in your
pubspec.yaml and pub get the latest version compatible with your Dart version.
|Dart Version||Lint Version|
Comparison to discontinued package:pedantic #
Google publicly shares their internal rules as
package:pedantic in open-source.
It represents what Google is enforcing internally throughout all Dart code.
For a lint rule to be added to pedantic, Google has to change all code which doesn't follow the style.
This strict practice results in only 27/150+ rules to be enabled. While some are contradictory to each other and can not enabled together, a big chunk of rules isn't enabled because it requires too much work to update all of Googles existing code.
For developers outside Google, it is the norm to have separate lint rules per project. One project might enable more rules then others.
lint enables a majority of lint rules, leaving out contradictory and very opinionated rules.
