  It works like this...

  Define the component:

  import 'package:react/react.dart' as react;
  
  final SomeWidget = react.registerFunctionComponent(_SomeWidget, displayName: 'SomeWidget');
  
  _SomeWidget(Map props) {
    // You can use hooks in here, too!
    
    return react.div({}, [
      // Some children...
    ]);
  }

  Render the component (exact same consumer API as a class-based component):

  import 'package:react/react_dom.dart' as react_dom;
  import 'some_widget.dart'; // Where your component is defined
  
  main() {
    final renderedWidget = SomeWidget({
      // put some props here
    }, [
      // put some children here!
    ]);
  
    react_dom.render(renderedWidget, querySelector('#idOfSomeNodeInTheDom'));
  }
