dependencies:
  gtext: ^0.0.3

示例代码

下面是一个完整的示例代码，展示了如何使用 GText 插件进行文本翻译。

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

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

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const MyHomePage(title: 'GText Demo Home Page'),
    );
  }
}

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

  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(
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            const GText("Тест приложения"),
            const GText(
              'You have pushed the button this many times:',
              toLang: 'zh-cn',
            ),
            Text(
              '$_counter',
              style: Theme.of(context).textTheme.headline4,
            ),
          ],
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: _incrementCounter,
        tooltip: 'Increment',
        child: const GText("Increment"),
      ), // This trailing comma makes auto-formatting nicer for build methods.
    );
  }
}

使用说明

1. 本地翻译：

   import 'package:gtext/gtext.dart';
   
   GText("Hello, World!", toLang: 'de')
   

2. 初始化全局语言（无需设置 toLang 参数）：

   import 'package:gtext/gtext.dart';
   
   void main() {
     GText.init(to: 'en', enableCaching: false);
     runApp(App());
     // You can write GText("Привет, мир!")
   }
