dart_code_quality 0.3.0

A collection of analyzer rules for Dart and Flutter development.

Dart Code Quality

Dart code quality (DCQ) is a collection of analyzer rules designed to aid in Dart, and Flutter development. Additionally popular frameworks such as Riverpod have their own rules.

Rules are separated into distinct categories:

• Critical
• Correctness
• Maintainability
• Performance
• Style

Style rules are mostly recommended for ensuring homogeneity when working on a team. The rest can be used anywhere, and it's highly recommended to use the Critical rules.

Usage

Add the plugin and include the recommended preset in your analysis_options.yaml:

include: package:dart_code_quality/recommended.yaml

plugins:
  dart_code_quality: ^0.3.0

Configuring rules

Enable, disable, or configure individual rules via dart_code_quality: rules::

dart_code_quality:
  rules:
    # Disable a recommended rule
    avoid-non-null-assertion: false
    # Enable an opt-in rule
    prefer-conditional-expressions: true
    # Enable with options
    avoid-long-files:
      max-length: 200

Suppressing a diagnostic

// ignore: avoid-dynamic
dynamic x = 1;
