Flutter情绪识别插件plutchik的使用

Plutchik的情绪轮盘

Plutchik的情绪轮盘是一个用于情绪识别和展示的工具，它基于心理学家Robert Plutchik提出的情绪理论。该插件允许用户通过点击情绪轮盘上的不同区域来选择或识别情绪。

使用方法

要使用Plutchik插件，首先需要在你的项目中引入它。你可以通过以下步骤进行设置：

1. 在pubspec.yaml文件中添加依赖：

   dependencies:
     plutchik: ^版本号
   

2. 导入必要的库并在主函数中初始化应用：

   import 'package:flutter/cupertino.dart';
   import 'package:plutchik/l10n/generated/l10n.dart';
   import 'package:plutchik/plutchik.dart';
   import 'package:flutter/material.dart';
   import 'package:flutter_localizations/flutter_localizations.dart';
   
   void main() {
     WidgetsFlutterBinding.ensureInitialized();
     runApp(const MyApp());
   }
   

3. 创建一个主应用程序类，并配置支持的本地化语言：

   class MyApp extends StatelessWidget {
     const MyApp({Key? key}) : super(key: key);
   
     @override
     Widget build(BuildContext context) {
       return MaterialApp(
         title: 'Material App',
         home: const HomeScreen(),
         theme: ThemeData(
           colorScheme: ColorScheme.fromSeed(seedColor: Colors.blue),
           useMaterial3: true,
         ),
         supportedLocales: const [
           Locale("en", "US"),
           Locale("tr", "TR"),
           Locale("de", "DE"),
           Locale("es", "ES"),
           Locale("fr", "FR"),
           Locale("pt", "PT"),
           Locale("ru", "RU"),
         ],
         localizationsDelegates: const [
           LocaleProvider.delegate,
           GlobalMaterialLocalizations.delegate,
           GlobalWidgetsLocalizations.delegate,
           GlobalCupertinoLocalizations.delegate,
           DefaultCupertinoLocalizations.delegate
         ],
         localeResolutionCallback: (locale, supportedLocales) {
           for (var locale in supportedLocales) {
             if (locale.languageCode == locale.languageCode && locale.countryCode == locale.countryCode) {
               return locale;
             }
           }
           return supportedLocales.first;
         },
         debugShowCheckedModeBanner: false,
       );
     }
   }
   

4. 创建一个状态管理类来处理情绪的选择：

   class _HomeScreenState extends State<HomeScreen> {
     EducationCardType? selectedType;
   
     void updateType(EducationCardType? value) {
       if (selectedType != value && value != null) {
         selectedType = value;
         setState(() {});
       }
     }
   
     @override
     Widget build(BuildContext context) {
       return Scaffold(
         appBar: AppBar(
           foregroundColor: Colors.white,
           backgroundColor: Theme.of(context).colorScheme.primary,
           title: const Text('Plutchik Demo'),
         ),
         body: Column(
           children: [
             // 绘制情绪轮盘
             Container(
               color: Colors.transparent,
               transform: Matrix4.translationValues(-27, 0, 0),
               child: CustomPaint(
                 size: Size(
                   MediaQuery.of(context).size.width,
                   MediaQuery.of(context).size.width,
                 ),
                 painter: PlutchikCustomPainter(
                   context: context,
                   onTap: (value) {
                     updateType(value);
                   },
                   textStyle: const TextStyle(color: Colors.black, fontSize: 10),
                 ),
               ),
             ),
   
             // 显示选中的情绪
             if (selectedType != null) ...[
               Padding(
                 padding: const EdgeInsets.only(top: 100),
                 child: Text(
                   selectedType!.xGetName(context),
                 ),
               ),
             ],
           ],
         ),
       );
     }
   }
