This rule has a quick fix available.

DO use key in widget constructors.

It's a good practice to expose the ability to provide a key when creating public widgets.

BAD:

class MyPublicWidget extends StatelessWidget {
}

GOOD:

class MyPublicWidget extends StatelessWidget {
  MyPublicWidget({super.key});
}

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