Supported Lint Rules

This list is auto-generated from our sources.

Rules are organized into familiar rule groups.

• errors -

  Possible coding errors.

• style -

  Matters of style, largely derived from the official Dart Style Guide.

• pub -

  Pub-related rules.

In addition, rules can be further distinguished by maturity. Unqualified rules are considered stable, while others may be marked experimental to indicate that they are under review. Lints that are marked as deprecated should not be used and are subject to removal in future Linter releases.

Rules can be selectively enabled in the analyzer using analysis options or through an analysis options file.

• An auto-generated list enabling all options is provided here.

As some lints may contradict each other, only a subset of these will be enabled in practice, but this list should provide a convenient jumping-off point.

Many lints are included in various predefined rulesets:

• core for official "core" Dart team lint rules.
• recommended for additional lint rules "recommended" by the Dart team.
• flutter for rules recommended for Flutter projects (flutter create enables these by default).

Rules included in these rulesets are badged in the documentation below.

These rules are under active development. Feedback is welcome!
