Official Dart lint rules. Defines the 'core' and 'recommended' set of lints suggested by the Dart team.
Official Dart lint rules. #
The Dart linter is a static analyzer for identifying possible problems in your Dart source code. More than a hundred linter rules are available, checking anything from potential typing issues, coding style, and formatting.
package:lints contains the official selections of lints that the
Dart team encourages using.
Two sets of lints are available:
Core lints: Lints that help identify critical issues that are likely to lead to problems when running or consuming Dart code. All code should pass these lints.
Recommended lints: Lints that help identify additional issues that may lead to problems when running or consuming Dart code, and lints that enforce writing Dart using a single, idiomatic style and format. All code is encouraged to pass these lints. The recommended lints include all the core lints.
Where these lints are used #
When creating new Dart project using the
dart create command,
the lints from
package:lints are enabled by default.
When uploading a package to the pub.flutter-io.cn package repository, packages are awarded pub points depending on whether they pass at least the 'core' lints (note: the recommended lints automatically include all core lints).
For documentation on the individual lints, see the linter rules page on dart.dev.
How to enable these lints #
For new apps created with
dart create, the lints are enabled by default.
For existing apps or packages, take these steps to enable these lints:
- In a terminal, located at the root of your package, run this command:
dart pub add --dev lints
- Create a new
analysis_options.yamlfile, next to the pubspec, that includes the lints package:
Customizing the pre-defined lint sets #
You can customize the pre-defined lint sets, both to disable one or more of the lints included, or to add additional lints. For details see customizing static analysis.
