avoid_private_typedef_functions

Avoid private typedef functions.

NOTE: As a private typedef can make some code more readable, this lint rule has been deprecated as of Dart 3.13 and is set to be removed in a future release of the Dart SDK. Remove all inclusions of this lint from your analysis options. If you wish to keep enforcing it, consider implementing the rule with an analyzer plugin.

AVOID private typedef functions used only once. Prefer inline function syntax.

BAD:

typedef void _F();
m(_F f);

GOOD:

m(void Function() f);

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

linter:
  rules:
    - avoid_private_typedef_functions

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

linter:
  rules:
    avoid_private_typedef_functions: true
