Flutter ios16 rotation issue

I have developed with flutter and i have a problem in Device Rotation.

for example, when an user clicked a button, it makes rotate device.(below code)

SystemChrome.setPreferredOrientations(
  _isPortrait
      ? [
          DeviceOrientation.landscapeRight,
        ]
      : [
          DeviceOrientation.portraitUp,
        ],
)

and end of rotation, i will change rotation landscape + portrait(to rotate user device directly)

so i used following code.

SystemChrome.setPreferredOrientations(
  _isPortrait
      ? [
          DeviceOrientation.landscapeRight,
        ]
      : [
          DeviceOrientation.portraitUp,
        ],
).then((value) {
  SystemChrome.setPreferredOrientations([]);
});

It is working under iOS16.

But in iOS16, it is not working.(after change rotation, it is rollback origin rotation with animation)

Who know this problem?

Thanks.

Solution

  • Previously apple was using UIDevice.current.setValue(value, forKey: "orientation") to set the orientation after iOS 16 the mentioned method got deprecated because of some bugs, instead of that they are recommending us to use windowScene.requestGeometryUpdate(.iOS(interfaceOrientations: orientation)) this method. for the further reference https://developer.apple.com/forums/thread/707735?answerId=726322022#726322022
