over_react_non_defaulted_prop

This diagnostic detects when a prop that has a default value in a function component is used directly instead of its defaulted equivalent, since this is usually a mistake, and can result in unexpected null errors.

BAD: props.content is used instead of content which defaults the prop.

import 'package:over_react/over_react.dart';

part 'foo.over_react.g.dart';

UiFactory<FooProps> Foo = uiFunction(
  (props) {
    // Default props
    final content = props.content ?? 'abc';

    return Dom.div()(props.content);
  },
  _$FooConfig, // ignore: undefined_identifier
);

mixin FooProps on UiProps {
  String content;
}

GOOD:

    // Default props
    final content = props.content ?? 'abc';

    return Dom.div()(content);

);
