unnecessary_raw_strings

Learn about the unnecessary_raw_strings linter rule.

Stable

Fix available

Released in Dart 2.8

Unnecessary raw string.

Use raw string only when needed.

BAD:

dart

var s1 = r'a';

GOOD:

dart

var s1 = 'a';
var s2 = r'$a';
var s3 = r'\a';

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

analysis_options.yaml

yaml

linter:
  rules:
    - unnecessary_raw_strings

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

analysis_options.yaml

yaml

linter:
  rules:
    unnecessary_raw_strings: true
