It’s time for a challenge on Flutter widget creation. Currently, we have a an app that has lots of different domains. It’d be nice for the user to navigate to a filter page and to filter out all the courses.

class FilterPage extends StatefulWidget {
  const FilterPage({ Key? key }) : super(key: key);

  @override
  _FilterPageState createState() => _FilterPageState();
}

class _FilterPageState extends State<FilterPage> {
  @override
  Widget build(BuildContext context) {
    return Container(

    );
  }
}

class _FilterPageState extends State<FilterPage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(Strings.filter),
      ),
      body: const Text('Filter'),
    );
  }
}

import '../../strings.dart';

  appBar: AppBar(
    title: Text(Strings.appTitle),
    actions: <Widget>[
      IconButton(
        icon: const Icon(Icons.filter_list),
        onPressed: () => Navigator.of(context).push<MaterialPageRoute>(
            MaterialPageRoute(builder: (_) => const FilterPage())),
      )
    ],
  ),

import 'ui/filter/filter_page.dart';
