I was using Flutter more than a week, and wanted to create an Arabic (right-to-left) app.
I was reading Internationalizing Flutter Apps, but it didn't mention how to set the layout direction.
So, how to show right-to-left (RTL) layout 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
];
The best and shortest way to set RTL configuration for the entire app.
void main() {
runApp(
MaterialApp(
home: Directionality( // add this
textDirection: TextDirection.rtl, // set this property
child: HomePage(),
),
),
);
}
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,
);
},
),
);
},
.
.
.
);
If you need to display text in reverse direction then just set it's textdirection property to TextDirection.rtl.
Example code for TextField widget,
TextField(
textDirection: TextDirection.rtl,
decoration: InputDecoration(
labelText: "Enter Pashto Name",
),
),
Example code for Text widget,
Text(
"This text is in the other direction!"
textDirection: TextDirection.rtl,
),
Just append this to your material app:
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,
);
},
),
);
},
if you use flutter_localizations:
sdk: flutter
add these line to change your app direction
supportedLocales: [
Locale("fa", "IR"),
Locale("en", 'US'),
],
locale: Locale("fa", "IR") // this is important line if not add this Apps will not change direction
GetMaterialApp( textDirection: TextDirection.rtl, home: SignUpScreen() // const HomeExpert() );
I'm Using CodeAnywhere as my IDE and I wanted to use testing Environment not development.
how can I do that?
when I try Console.Log(process.env)
this comes out

I if I can add some variables into this environment, then how can I do that?
if I want to create another Environment, then how can I do that?
i try to change the default selected format in ckeditor
i added it in the styles.js
CKEDITOR.stylesSet.add('mystyles', [
{name: 'My styly style', element: 'p', styles: {'color': 'blue'}},
]);
and when my instance of ck loads i would lije to select by default the format when i click in the editor to change the texte .
Anyone has the answer
thanks
Try to add this line in your config.js:
config.format_p = { element: 'p', attributes: { 'class': 'color_blue' } };
** Do not forget to add (in your css)
.color_blue{
color:blue;
}
I'm using the Require Optimizer to combine all of our source files in to a single file. That works great, but when I try to set optimize: 'uglify' or optimze: 'uglify2' I don't get mangled output: everything is combined in to a single line of a single file, but that line is filled with the original variable names.
I've tried setting various uglifyer options like:
uglify: {no_mangle: false}
or:
uglify2: {mangle: true}
but they don't work. Can anyone explain how I can get the optimizer to mangle its output?
EDIT
Here's my build.js file:
({
baseUrl: ".",
paths: {
template: 'ext/require/hbs',
text: 'ext/require/text'
},
name: "main",
optimize: "uglify",
out: "../built/main-built.js",
uglify: {
beautify: false,
space_colon: true,
no_mangle: false,
}
})
I wound up fixing this by updating our copy of Require.
I use the plugin !text, and want that after optimization by r.js, user to edit their own templates. But after optimization I get an error: Dynamic load not allowed.
build.js
{
baseUrl: "f/app",
appDir: "..",
dir: "dist",
modules: [
{
name: "catalog"
}
],
stubModules: ['text'],
optimizeAllPluginResources: false,
inlineText: false,
paths: {
app: '../libs',
jquery: 'empty:',
underscore: 'empty:',
backbone: 'empty:',
marionette: 'empty:',
JSON: 'empty:',
// Plugins
text: '../libs/rjs-text',
},
exclude: ["jquery","underscore","backbone","marionette", 'JSON', 'text']
}
This is generally how it is possible to implement?
Without any example code this is virtually impossible to answer (as I said in my comment). However, just to take a shot in the dark, perhaps your problem is that you're using variables for your require imports, and that is annoying the require optimizer. Using literal arrays should solve that; in other words don't do:
var myDependencies = ['foo', 'bar'];
define(myDependencies, function(...
do:
define(['foo', 'bar'], function(...
