BAD:

names.forEach((name) {
  print(name);
});

GOOD:

names.forEach(print);

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

linter:
  rules:
    - unnecessary_lambdas

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

linter:
  rules:
    unnecessary_lambdas: true
