如何在string - flutter中使用列表

void main() {
  List<String> words = ['Hello', 'world', 'from', 'Flutter'];

  // 使用join方法连接列表中的字符串
  String sentence = words.join(' ');
  print(sentence); // 输出: Hello world from Flutter

  // 或者使用字符串插值
  String interpolatedSentence = '${words[0]} ${words[1]} ${words[2]} ${words[3]}';
  print(interpolatedSentence); // 输出: Hello world from Flutter

  // 在Flutter widget中使用
  runApp(MyApp(words: words));
}

class MyApp extends StatelessWidget {
  final List<String> words;

  MyApp({required this.words});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(title: Text('String with List Example')),
        body: Center(
          child: Text('${words.join(' ')}'),
        ),
      ),
    );
  }
}

List<dynamic> mixedList = ['Hello', 123, 'world']; // 包含非字符串元素

// 将所有元素转换为字符串
String mixedSentence = mixedList.map((e) => e.toString()).join(' ');
print(mixedSentence); // 输出: Hello 123 world
