How to use a preset #

Take these steps to enable a preset:

1. Install this package as a dev dependency:

   dart pub add --dev dart_code_metrics_presets
   

   or:

   flutter pub add --dev dart_code_metrics_presets
   

2. For DCM configuration add the extents entry:

   dart_code_metrics:
     extends:
       - package:dart_code_metrics_presets/all.yaml
   

Disabling or reconfiguring a rule from the preset #

To disable a rule, simply set its value to false:

dart_code_metrics:
  extends:
    - package:dart_code_metrics_presets/all.yaml
  rules:
    - avoid-banned-imports: false

To reconfigure a rule, that is included into a preset:

dart_code_metrics:
  extends:
    - package:dart_code_metrics_presets/all.yaml
  rules:
    - arguments-ordering:
        child-last: true

Defining a custom preset #

Any other preset can be passed to the extends entry. To create a custom preset create a yaml file with the same structure as for regular DCM configuration.
