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

linter:
  rules:
    - unnecessary_to_list_in_spreads

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

linter:
  rules:
    unnecessary_to_list_in_spreads: true
