Take a look at this example that I've pieced together from the Planets-Flutter tutorial along with the code below it. import "package:flutter/material.dart"; class Page extends StatelessWidget { @override Widget build(BuildContext context) { return Column(children : <Widget>[GradientAppBar("Custom Gradient App Bar"), Container()],); } } class GradientAppBar extends StatelessWidget { final String title; final double barHeight = 50.0; GradientAppBar(this.title); @override Widget build(BuildContext context) { final double statusbarHeight = MediaQuery .of(context) .padding .top; return new Container( padding: EdgeInsets.only(top: statusbarHeight), height: statusbarHeight + barHeigh...

Answer : Simply use Directionality: new Directionality( textDirection: TextDirection.rtl, child: TextField( textAlign: TextAlign.right, controller: _textEdittingControler_bookName, autofocus: true, decoration: new InputDecoration( labelText: "افزودن کتاب", hintText: "نام کتاب را وارد کنید" ), ) Directionality's docs Can be used textAlign TextFormField( textAlign: TextAlign.right, decoration: InputDecoration( hintText: 'ادخل تفاصيل الكتابة الخاصة بك', ),
