prefer_inlined_adds

Inline list item declarations where possible.

Declare elements in list literals inline, rather than using add and addAll methods where possible.

BAD:

var l = ['a']..add('b')..add('c');
var l2 = ['a']..addAll(['b', 'c']);

GOOD:

var l = ['a', 'b', 'c'];
var l2 = ['a', 'b', 'c'];

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

linter:
  rules:
    - prefer_inlined_adds

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

linter:
  rules:
    prefer_inlined_adds: true
