use_named_constants

Use predefined named constants.

Where possible, use already defined const values.

BAD:

const Duration(seconds: 0);

GOOD:

Duration.zero;

To enable the use_named_constants rule, add use_named_constants under linter > rules in your analysis_options.yaml file:

linter:
  rules:
    - use_named_constants

If you're instead using the YAML map syntax to configure linter rules, add use_named_constants: true under linter > rules:

linter:
  rules:
    use_named_constants: true
