Unnecessary toList() in spreads.

Unnecessary toList() in spreads.

BAD:

children: <Widget>[
  ...['foo', 'bar', 'baz'].map((String s) => Text(s)).toList(),
]

GOOD:

children: <Widget>[
  ...['foo', 'bar', 'baz'].map((String s) => Text(s)),
]

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
