right-to-left (RTL) in flutter
you have two choices :
1. force a locale ( and direction ) on all devices
-- method 1: with localization
add flutter_localizations
package to your pubspec.yml
dependencies:
flutter:
sdk: flutter
flutter_localizations:
sdk: flutter
then
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,
.
.
.
);
-- method 2: without localization
MaterialApp(
.
.
.
builder: (context, child) {
return Directionality(
textDirection: TextDirection.rtl,
child: child,
);
},
.
.
.
);
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
)
add flutter_localizations
package to your pubspec.yml
dependencies:
flutter:
sdk: flutter
flutter_localizations:
sdk: flutter
then
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
],
.
.
.
);
note : rtl languages in flutter are:
[
'ar', // Arabic
'fa', // Farsi
'he', // Hebrew
'ps', // Pashto
'ur', // Urdu
];
You need to create a Builder and pass it the layout direction using TextDirection.rtl
new MaterialApp(
title: 'Flutter RTL',
color: Colors.grey,
builder: (BuildContext context, Widget child) {
return new Directionality(
textDirection: TextDirection.rtl,
child: new Builder(
builder: (BuildContext context) {
return new MediaQuery(
data: MediaQuery.of(context).copyWith(
textScaleFactor: 1.0,
),
child: child,
);
},
),
);
},
.
.
.
);
