How to change screen orientation in Flutter

Changing screen orientation and handle orientation related config

The mobile application usually develops to support both in portrait and landscape mode without any issue. But in some special case, you may need to set the orientation of the application to fix direction to get proper real state space to each component

Set the orientation in flutter

First, you have to import the services package.

 import 'package:flutter/services.dart';

Next, you can set orientation by setting the value to setPreferredOrientations method in SystemChrome class. In the Flutter the application entry point is the main method. So you can set orientation before call the runApp method in the main method. But if you need to call a binding before the runApp method, you must call the ensureInitialized method in WidgetsFlutterBinding class.

        void main() {

Set landscape orientation only


You can set either landscapeLeft or landscapeRight to make it work in one way.

Set portrait orientation only


If you set both portraitUp and portraitDown as orientation when you tilt your phone upside down it will rotate the app. If you don’t like to work in upside-down orientation, you can just set only the portraitUp.

Change orientation dynamically

This is the same as above, you just need to use the same method when clicking a button or trigger some action.

              child: Text("Portrait"),
              onPressed: (){
