Dalam tugas ini, saya membuat aplikasi nama random dan fitur favourite kata menggunakan dart dan dibantu dengan Visual Studio Code. Berikut adalah kode program dan hasil pengerjaannya.

Source Code:

main.dart:

import 'package:english_words/english_words.dart';
import 'package:flutter/material.dart';
import 'package:provider/provider.dart';
void main() {
  runApp(MyApp());
}
class MyApp extends StatelessWidget {
  const MyApp({super.key});
  @override
  Widget build(BuildContext context) {
    return ChangeNotifierProvider(
      create: (context) => MyAppState(),
      child: MaterialApp(
        title: 'Namer App',
        theme: ThemeData(
          useMaterial3: true,
          colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepOrange),
        ),
        home: MyHomePage(),
      ),
    );
  }
}
class MyAppState extends ChangeNotifier {
  var current = WordPair.random();
  void getNext() {
    current = WordPair.random();
    notifyListeners();
  }
  var favorites = <WordPair>[];
  void toggleFavorite() {
    if (favorites.contains(current)) {
      favorites.remove(current);
    } else {
      favorites.add(current);
    }
    notifyListeners();
  }
}
class MyHomePage extends StatefulWidget {
  @override
  State<MyHomePage> createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
  var selectedIndex = 0;
  @override
  Widget build(BuildContext context) {
    Widget page;
    switch (selectedIndex) {
      case 0:
        page = GeneratorPage();
        break;
      case 1:
        page = FavoritesPage();
        break;
      default:
        throw UnimplementedError('no widget for $selectedIndex');
    }
