avoid_types_on_closure_parameters

Avoid annotating types for function expression parameters.

This rule is available as of Dart 2.0.

This rule has a quick fix available.

Incompatible rules: always_specify_types

AVOID annotating types for function expression parameters.

Annotating types for function expression parameters is usually unnecessary because the parameter types can almost always be inferred from the context, thus making the practice redundant.

BAD:

var names = people.map((Person person) => person.name);

GOOD:

var names = people.map((person) => person.name);

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

linter:
  rules:
    - avoid_types_on_closure_parameters
