Flutter手语翻译插件mobile_sign_language_translation的使用

Flutter手语翻译插件mobile_sign_language_translation的使用

使用方法

要使用 mobile_sign_language_translation 插件，首先需要将其包裹在你的 MaterialApp 中，并传入必要的信息。

示例代码（main.dart）

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

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

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

  @override
  Widget build(BuildContext context) {
    // 包裹 MaterialApp 并传入请求密钥和URL
    return SignForDeaf(
      requestKey: 'YOUR_API_KEY', // 替换为你的API密钥
      requestUrl: 'YOUR_API_URL', // 替换为你的API URL
      child: MaterialApp(
        title: 'Flutter Demo',
        theme: ThemeData(
          colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
          useMaterial3: true,
        ),
        home: const MyHomePage(title: 'Flutter Demo Home Page'),
      ),
    );
  }
}

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

  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  int _counter = 0;

  void _incrementCounter() {
    setState(() {
      _counter++;
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        backgroundColor: Theme.of(context).colorScheme.inversePrimary,
        title: Text(widget.title),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            // 使用 SignForDeafArea 组件来展示手语翻译区域
            const SignForDeafArea(
              requestKey: 'YOUR_API_KEY', // 替换为你的API密钥
              requestUrl: 'YOUR_API_URL', // 替换为你的API URL
              child: Text(
                '你已经按了按钮这么多次：',
              ),
            ),
            Text(
              '$_counter',
              style: Theme.of(context).textTheme.headlineMedium,
            ),
          ],
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: _incrementCounter,
        tooltip: '增加计数',
        child: const Icon(Icons.add),
      ),
    );
  }
}

注意事项

如果你的应用程序使用了多个页面或替代路由结构，确保在每个页面上重建该组件！

示例代码（使用 MaterialApp.builder）

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

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

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

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      builder: (context, child) {
        // 在 builder 中包裹 SignForDeaf 组件
        return SignForDeaf(
          requestKey: 'YOUR_API_KEY', // 替换为你的API密钥
          requestUrl: 'YOUR_API_URL', // 替换为你的API URL
          child: child!,
        );
      },
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: const MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

示例代码（使用 AutoRoute）

路由配置

import 'package:auto_route/auto_route.dart';

@AutoRouterConfig()
class AppRouter extends $AppRouter {
  @override
  List<AutoRoute> get routes => [...routesList];

  static PageRouteBuilder signForDeafBuilder(BuildContext context, Widget child,
      Page<dynamic> page, RouteTransitionsBuilder transitionsBuilder) {
    return PageRouteBuilder(
      settings: page,
      pageBuilder: (_, __, ___) {
        return SignForDeaf(
          requestKey: 'YOUR_API_KEY', // 替换为你的API密钥
          requestUrl: 'YOUR_API_URL', // 替换为你的API URL
          child: child!,
        );
      },
      transitionsBuilder: transitionsBuilder,
    );
  }
}

路由列表

List<AutoRoute> routesList = [
  CustomRoute(
    page: Route.page,
    customRouteBuilder: (context, child, page) => AppRouter.signForDeafBuilder(
        context, child, page, TransitionsBuilders.fadeIn),
  ),
];
