Flutter单词拼写检查插件scrabble_word_checker的使用

描述

Scrabble ODS 单词检查器是一个Flutter包，允许你检查一个单词是否在官方Scrabble字典（ODS）中。该包易于使用，可以在几分钟内集成到你的Flutter应用中。

要使用该包，只需将其导入到项目中并调用isValidWord()方法。该方法接受一个单词作为参数，并返回一个布尔值，表示该单词是否在ODS中。

安装

在pubspec.yaml文件中添加依赖项：

dependencies:
  scrabble_word_checker: ^0.0.4

然后获取依赖项：

$ flutter pub get

支持的语言

• 法语
• 英语

使用

首先，在代码中的任何地方导入该包：

import 'package:scrabble_word_checker/scrabble_word_checker.dart';

初始化单词检查类：

final ScrabbleWordChecker wordChecker = ScrabbleWordChecker(language: ScrabbleLanguage.english);

检查任意单词：

bool isCorrect1 = wordChecker.isValidWord("aa"); // 预期结果: true
bool isCorrect2 = wordChecker.isValidWord("a"); // 预期结果: false

获取单词价值：

int value = wordChecker.getWordValue("black"); // 预期结果: 13

更改语言：

wordChecker.changeLanguage(ScrabbleLanguage.french);

以下是一个完整的示例代码，展示了如何在Flutter应用中使用scrabble_word_checker插件：

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

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

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const MyHomePage(title: 'Scrabble word checker'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key, required this.title});
  final String title;

  [@override](/user/override)
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  final ScrabbleWordChecker wordChecker = ScrabbleWordChecker();
  final GlobalKey<FormState> formKey = GlobalKey<FormState>();
  final TextEditingController controller = TextEditingController();
  String word = "";
  bool valid = false;
  int value = 0;
  ScrabbleLanguage language = ScrabbleLanguage.french;

  [@override](/user/override)
  void dispose() {
    controller.dispose();
    super.dispose();
  }

  [@override](/user/override)
  void initState() {
    wordChecker.changeLanguage(language);
    super.initState();
  }

  void checkWord() {
    word = "";
    valid = false;
    setState(() {});
    if (!formKey.currentState!.validate()) {
      return;
    }
    valid = wordChecker.isValidWord(controller.text.trim());
    value = wordChecker.getWordValue(controller.text.trim());
    word = controller.text.trim();
    setState(() {});
  }

  [@override](/user/override)
