Import package:flutter/services.dart
, then
Put the SystemChrome.setPreferredOrientations
inside the Widget build()
method.
Example:
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
SystemChrome.setPreferredOrientations([
DeviceOrientation.portraitUp,
DeviceOrientation.portraitDown,
]);
return new MaterialApp(...);
}
}
Update
This solution mightn’t work for some IOS devices as mentioned in the updated flutter documentation on Oct 2019.
They Advise to fixed the orientation by setting UISupportedInterfaceOrientations in Info.plist like this
<array>
<string>UIInterfaceOrientationPortrait</string>
</array>
