Configuring Metrics

Metrics are one of the core building blocks of DCM. Metrics help you understand the complexity of your code and identify areas that may be difficult to maintain or test.

All metrics are configurable.

Enabling a Metric​

To enable a metric add its id to the metrics entry:

analysis_options.yaml
dart_code_metrics:
  metrics:
    cyclomatic-complexity: 20

Excluding Files for All Metrics​

To exclude files from a metrics report provide a list of regular expressions for ignored files:

analysis_options.yaml
dart_code_metrics:
  metrics-exclude:
    - test/**
    - lib/src/some_file.dart
