Example:​

custom_lint:
  rules:
    - number_of_parameters:
      max_parameters: 2

BAD:​

void fn(a, b, c) {} // LINT
class C {
  void method(a, b, c) {} // LINT
}

GOOD:​

void fn(a, b) {} // OK
class C {
  void method(a, b) {} // OK
}

Parameters​

max_parameters (int)​

Maximum number of parameters allowed before a warning is triggered.
