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?

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)

void main() {
  SystemChrome.setPreferredOrientations([DeviceOrientation.landscapeLeft])
    .then((_) {
      runApp(new MyApp());
    });
}

SystemChrome.setPreferredOrientations returns a Future. Wait until that’s done and then we can start our app.

Add this line of code in your main.dart file SystemChrome.setPreferredOrientations([DeviceOrientation.portraitUp]);
