我有一个笔记应用程序,允许用户输入笔记 我希望如果用户使用的语言是阿拉伯语,则将文本方向设置为 rtl,否则在文本字段和我使用 listTile 的详细信息屏幕中将其设置为 ltr
我该怎么做?
来自官方文档
默认情况下,Flutter 仅提供美国英语本地化。要添加对其他语言的支持,应用程序必须指定其他 MaterialApp(或 CupertinoApp)属性,并包含一个名为 flutter_localizations 的包。截至 2020 年 11 月,该软件包支持 78 种语言。
要使用 flutter_localizations,请将包作为依赖项添加到 pubspec.yaml 文件中:
dependencies:
flutter:
sdk: flutter
flutter_localizations: # Add this line
sdk: flutter # Add this line
接下来,运行 pub get packages,然后导入 flutter_localizations 库并为 MaterialApp 指定localizationsDelegates 和supportedLocales:
import 'package:flutter_localizations/flutter_localizations.dart';
// TODO: uncomment the line below after codegen
// import 'package:flutter_gen/gen_l10n/app_localizations.dart';
// ...
MaterialApp(
localizationsDelegates: [
// ... app-specific localization delegate[s] here
// TODO: uncomment the line below after codegen
// AppLocalizations.delegate,
GlobalMaterialLocalizations.delegate,
GlobalWidgetsLocalizations.delegate,
GlobalCupertinoLocalizations.delegate,
],
supportedLocales: [
const Locale('en', ''), // English, no country code
const Locale('ar', ''), // Arabic, no country code
const Locale.fromSubtags(languageCode: 'zh'), // Chinese *See Advanced Locales below*
// ... other locales the app supports
],
// ...
)
引入 flutter_localizations 包并添加上面的代码后,Material 和 Cupertino 包现在应该在 78 个受支持的语言环境之一中正确本地化。小部件应适应本地化消息,
along with correct left-to-right and right-to-left layout
。尝试将目标平台的区域设置切换为阿拉伯语 (ar),并注意消息应本地化,并且小部件的布局应考虑从右到左的布局。
dependencies:
flutter:
sdk: flutter
intl: ^0.17.0 # Use the latest version of intl package
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
// Get the locale of the device
Locale deviceLocale = WidgetsBinding.instance!.window.locale;
// Check if the language code of the locale is Arabic
bool isArabic = deviceLocale.languageCode == 'ar';
return MaterialApp(
home: Scaffold(
body: Center(
child: Text(
isArabic ? 'العربية' : 'English',
textDirection: isArabic ? TextDirection.rtl : TextDirection.ltr,
),
),
),
);
}
}
尝试使用 langdetect(如果您使用 tkinter)
from langdetect import detect
from tkinter import *
from tkinter.constants import *
arabictext = "مرحبا"
root = Tk()
text = Text(root)
lang = detect(arabictext)
if lang == "ar":
text.tag_configure('tag-right', justify='right')
text.insert('end', arabictext, 'tag-right')
text.grid()
root.mainloop()
