颤动中的从右到左 (RTL) [英] right-to-left (RTL) in flutter

问题描述

我使用 Flutter 一个多星期，想创建一个阿拉伯语(从右到左)应用.

I was using Flutter more than a week, and wanted to create an Arabic (right-to-left) app.

我正在阅读Internationalizing Flutter Apps，但没有提到如何设置布局方向.

I was reading Internationalizing Flutter Apps, but it didn't mention how to set the layout direction.

那么，如何在 Flutter 中显示从右到左 (RTL) 的布局?

So, how to show right-to-left (RTL) layout in Flutter?

推荐答案

你有两个选择:

1.在所有设备上强制使用区域设置(和方向)

-- 方法一:本地化

-- method 1: with localization

将 flutter_localizations 包添加到您的 pubspec.yml

dependencies:
  flutter:
    sdk: flutter
  flutter_localizations:
    sdk: flutter

然后

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

MaterialApp(
  localizationsDelegates: [
    GlobalCupertinoLocalizations.delegate,
    GlobalMaterialLocalizations.delegate,
    GlobalWidgetsLocalizations.delegate,
  ],
  supportedLocales: [
    Locale("fa", "IR"), // OR Locale('ar', 'AE') OR Other RTL locales
  ],
  locale: Locale("fa", "IR") // OR Locale('ar', 'AE') OR Other RTL locales,
  .
  .
  .
);

-- 方法 2: 没有本地化

-- method 2: without localization

MaterialApp(
  .
  .
  .
  builder: (context, child) {
    return Directionality(
      textDirection: TextDirection.rtl,
      child: child,
    );
  },
  .
  .
  .
);

2.根据设备区域设置布局方向(如果用户手机区域设置是 RTL 语言并且存在于 supportedLocales 中，则您的应用以 RTL 模式运行，否则您的应用是 LTR )

2. set layout direction according to device locale ( if user phone locale is a RTL language and exist in supportedLocales, your app run in RTL mode, otherwise your app is LTR )

将 flutter_localizations 包添加到您的 pubspec.yml

dependencies:
  flutter:
    sdk: flutter
  flutter_localizations:
    sdk: flutter

然后

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

MaterialApp(
  localizationsDelegates: [
    GlobalCupertinoLocalizations.delegate,
    GlobalMaterialLocalizations.delegate,
    GlobalWidgetsLocalizations.delegate,
  ],
  supportedLocales: [
    Locale("en", "US"),
    Locale("fa", "IR"), // OR Locale('ar', 'AE') OR Other RTL locales
  ],
  .
  .
  .
);

注意:flutter 中的 rtl 语言是:

note : rtl languages in flutter are:

[
  'ar', // Arabic
  'fa', // Farsi
  'he', // Hebrew
  'ps', // Pashto
  'ur', // Urdu
];
