使用方法

导入包

首先，在你的Flutter项目中导入 filter_profanity_flutter 包：

import 'package:filter_profanity_flutter/filter_profanity_flutter.dart';

检查文本中是否包含冒犯性词汇

你可以使用 hasProfanity 函数来检查给定的文本是否包含冒犯性词汇：

bool containsOffensiveWords = hasProfanity('putin'); // 返回 true
bool isClean = hasProfanity('Hello'); // 返回 false

设置语言

你可以指定要检查的语言字典。例如，检查英语中的冒犯性词汇：

bool offensiveInEnglish = hasProfanity('putin', offensiveWords: englishOffensiveWords); // 返回 true

你也可以同时设置多种语言：

bool offensiveInMultipleLanguages = hasProfanity('putin', offensiveWords: ukrainianOffensiveWords + englishOffensiveWords); // 返回 true

示例代码

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

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

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

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

class MyHomePage extends StatefulWidget {
  @override
  _MyHomePageState createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  String _inputText = '';
  bool _containsProfanity = false;

  void _checkProfanity(String text) {
    setState(() {
      _inputText = text;
      _containsProfanity = hasProfanity(text);
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Filter Profanity Example'),
      ),
      body: Padding(
        padding: const EdgeInsets.all(16.0),
        child: Column(
          children: <Widget>[
            TextField(
              onChanged: (value) => _checkProfanity(value),
              decoration: InputDecoration(
                labelText: 'Enter text to check',
                border: OutlineInputBorder(),
              ),
            ),
            SizedBox(height: 20),
            Text(
              _containsProfanity ? 'Contains profanity!' : 'No profanity detected.',
              style: TextStyle(
                color: _containsProfanity ? Colors.red : Colors.green,
                fontSize: 18,
              ),
            ),
