Lock Device Orientation in Flutter

We may have noticed, in some mobile apps, we just can’t rotate them. Even if auto-rotation (or whatever thing it is) on, we can’t rotate the phone while we’re using those apps. To be honest, I first used this feature, just because I was too lazy to create a UI for landscape mode 😊. So I locked it and people will never be able to on Landscape mode.

In Flutter, It is quite easy to implement this. First of all, we have to import flutter/services.dart

import 'package:flutter/services.dart';

Then, In our Apps main function, just before we call runApp, call the below code,

await SystemChrome.setPreferredOrientations([DeviceOrientation.portraitUp]);

This will lock our app’s orientation to portrait mode. And if you wanna lock the orientation to landscape mode, you can change DeviceOrientation.portraitUp to DeviceOrientation.landscapeLeft or DeviceOrientation.landscapeRight

await SystemChrome.setPreferredOrientations([DeviceOrientation.landscapeLeft]);

await SystemChrome.setPreferredOrientations([DeviceOrientation.landscapeRight]);
