Flutter日文假名转换插件kana_kit的使用

KanaKit (かな・キット)

KanaKit 是一个用于检测和转写平假名、片假名和罗马字的Dart库。它主要移植自WaniKani’s WanaKana JavaScript库。

使用方法

要使用 KanaKit，您需要创建一个 KanaKit 类的实例。这个实例包含了所有可用的方法来检测和转换日语文本。

示例代码

import 'package:kana_kit/kana_kit.dart';

void main() {
  // 创建一个 KanaKit 实例。
  // 您可以提供一个类型为 KanaKitConfig 的配置。
  // 如果没有提供配置，则使用 KanaKitConfig.defaultConfig。
  const kanaKit = KanaKit();

  // 检测方法
  print(kanaKit.isJapanese('泣き虫。！～２￥ｚｅｎｋａｋｕ')); // true
  print(kanaKit.isKana('あーア')); // true
  print(kanaKit.isHiragana('すげー')); // true
  print(kanaKit.isKatakana('ゲーム')); // true
  print(kanaKit.isKanji('切腹')); // true
  print(kanaKit.isKanji('勢い')); // false
  print(kanaKit.isRomaji('Tōkyō and Ōsaka')); // true

  // 转换方法
  print(kanaKit.toKana('ONAJI buttsuuji')); // 'オナジ ぶっつうじ'
  print(kanaKit.toKana('座禅‘zazen’スタイル')); // '座禅「ざぜん」スタイル'
  print(kanaKit.toKana('batsuge-mu')); // 'ばつげーむ'

  print(kanaKit.toHiragana('toukyou, オオサカ')); // 'とうきょう、　おおさか'
  print(kanaKit.toKatakana('toukyou, おおさか')); // 'トウキョウ、　オオサカ'

  print(kanaKit.toRomaji('ひらがな　カタカナ')); // 'hiragana katakana'

  // 使用 upcaseKatakana 来大写从片假名转换过来的字符
  print(
      kanaKit.copyWithConfig(upcaseKatakana: true).toRomaji('ひらがな　カタカナ')
  ); // 'hiragana KATAKANA'
}

完整示例Demo

下面是一个完整的Flutter应用示例，展示了如何在Flutter项目中使用 kana_kit 插件：

import 'package:flutter/material.dart';
import 'package:kana_kit/kana_kit.dart';

void main() {
  runApp(MyApp());
}

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'KanaKit Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(title: 'KanaKit Demo Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  MyHomePage({Key? key, required this.title}) : super(key: key);

  final String title;

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

class _MyHomePageState extends State<MyHomePage> {
  final TextEditingController _controller = TextEditingController();
  final kanaKit = KanaKit();
  String _result = '';

  void _convertText(String text) {
    setState(() {
      _result = kanaKit.toKana(text);
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: Padding(
        padding: const EdgeInsets.all(16.0),
        child: Column(
          children: <Widget>[
            TextField(
              controller: _controller,
              decoration: InputDecoration(labelText: '输入日文'),
            ),
            SizedBox(height: 20),
            ElevatedButton(
              onPressed: () => _convertText(_controller.text),
              child: Text('转换为假名'),
            ),
            SizedBox(height: 20),
            Text('结果：$_result'),
          ],
        ),
      ),
    );
  }
}
