Flutter: How to avoid change orientation?

Question

I have a final user design with landscape orientation. User doesn't want/need portrait and it is needed to avoid automatic orientation change on iOS/Android. How can I achieve that?

Answer 1

SystemChrome is what you want

You can do something like in main.dart (don't forget import 'package:flutter/services.dart')

SystemChrome.setPreferredOrientations([
    DeviceOrientation.landscapeRight,
    DeviceOrientation.landscapeLeft,
]);

Unfortunately, when I do this in my application, the orientation will always be landscapeRight.

To lock the orientation for iOS you need to change the settings for the XCode project (use command 'open ios/Runner.xcworkspace' in terminal to open it)
