Warns when parameter names in function types are omitted.

Parameter names are used by the IDE's code completion instead of default names like p0 and p1. Therefore, providing them can improve the overall developer experience.

Example​

❌ Bad:

class LayoutBuilder {
  LayoutBuilder({this.builder});

  final Widget Function(BuildContext, ConstraintType) builder; // LINT: Prefer declaring names for function type parameters.
}

✅ Good:

class LayoutBuilder {
  LayoutBuilder({this.builder});

  // Correct, have names
  final Widget Function(BuildContext context, ConstraintType constraints) builder;
}
