Parameter names are used by IDEs code completion instead of default names like p0 and p1. Therefore, providing them can improve the overall DX.

Example

❌ Bad:

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

  final Widget Function(BuildContext, ConstraintType) builder; // LINT

class LayoutBuilder {

  final Widget Function(BuildContext context, ConstraintType constraints) builder;
}
