use_super_parameters

Use super-initializer parameters where possible.

"Forwarding constructor"s, that do nothing except forward parameters to their superclass constructors should take advantage of super-initializer parameters rather than repeating the names of parameters when passing them to the superclass constructors. This makes the code more concise and easier to read and maintain.

DO use super-initializer parameters where possible.

BAD:

class A {
  A({int? x, int? y});
}
class B extends A {
  B({int? x, int? y}) : super(x: x, y: y);
}

GOOD:

class A {
  A({int? x, int? y});
}
class B extends A {
  B({super.x, super.y});
}

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

linter:
  rules:
    - use_super_parameters

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

linter:
  rules:
    use_super_parameters: true
