use_key_in_widget_constructors

Use key in widget constructors.

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:

linter:
  rules:
    - use_key_in_widget_constructors

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

linter:
  rules:
    use_key_in_widget_constructors: true
