如何在 flutter 上隐藏旋转设备方向的变化？

   class MyApp extends StatelessWidget {
      @override
      Widget build(BuildContext context) {
        SystemChrome.setPreferredOrientations([
           DeviceOrientation.portraitUp,
           DeviceOrientation.portraitDown,
        ]);
        return MaterialApp(...);
     }
   }

Answer 1

//Use this inside main() of main.dart

//make sure that you have an instance of the WidgetsBinding.
WidgetsFlutterBinding.ensureInitialized();

await SystemChrome.setPreferredOrientations(
   [DeviceOrientation.portraitUp],
  ); // To set your device orientation throughout the App.
