Just starting an Ionic 2 app in Arabic language requires a RTL layout. I decided to go with the side menu template.
Adding the following line for configuring the app to RTL perfectly changed everything's direction, except for the back button which still pointed in the wrong direction:
<ion-nav #content [root]="rootPage" dir="rtl"></ion-nav>
This is how the navbar currently looks:

Is there any workaround until the Ionic team addresses RTL related issues?
If you want to change the alignment of your app from left-to-right (LTR) to right-to-left (RTL), instead of manually setting the dir attribute in the ion-nav, you can use the platform functionality provided by Ionic (docs)
private setProperAligment(): void {
if (this.selectedLanguage.rtl) {
this.platform.setDir('rtl', true);
// ...
} else {
this.platform.setDir('ltr', true);
// ...
}
}
By doing this, the dir="rtl" attribute will be added to the html tag of your application. While the Ionic team is working on resolving the issue related to the back button, you can add a CSS style rule in your app.scss file:
html[dir="rtl"] {
.back-button-icon.icon-md.back-button-icon-md.ion-md-arrow-back {
transform: rotate(180deg);
}
.back-button-icon.icon-ios.back-button-icon-ios.ion-ios-arrow-back {
transform: rotate(180deg);
padding: 0 5px;
}
}
When dealing with Ionic 5, I encountered a similar problem which I was able to resolve by executing:
document.dir = 'rtl';
Prior to this solution, I had followed the documentation's guidance to specify the direction in the app.component.html file as shown below:
<ion-app [dir]='dir'>
In this setup, where 'dir' represented my bound variable, everything functioned properly except for the back button direction. However, after implementing the document.dir = 'rtl' line of code, even that issue was resolved. Now, in my language switcher button code, I exclusively modify the document.dir.
