no_adjacent_strings_in_list

Don't use adjacent strings in list.

DON'T use adjacent strings in a list.

This can indicate a forgotten comma.

BAD:

List<String> list = <String>[
  'a'
  'b',
  'c',
];

GOOD:

List<String> list = <String>[
  'a' +
  'b',
  'c',
];

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

linter:
  rules:
    - no_adjacent_strings_in_list

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

linter:
  rules:
    no_adjacent_strings_in_list: true
