How to reset the APP orientation after taking a photo?

Question

I'm creating an iOS Landscape app by flutter.
I used image_picker to allow the app to take pictures with the camera.

After launching the camera, I rotated the device vertically and took a picture.
Then closed the camera, the APP SCREEN is still in portrait.
My hope is to automatically return to the landscape when the camera is closed.

info.plist

<key>UISupportedInterfaceOrientations</key>
<array>
    <string>UIInterfaceOrientationLandscapeLeft</string>
    <string>UIInterfaceOrientationLandscapeRight</string>
</array>
<key>UISupportedInterfaceOrientations~ipad</key>
<array>
    <string>UIInterfaceOrientationLandscapeLeft</string>
    <string>UIInterfaceOrientationLandscapeRight</string>
</array>

dart

final XFile? file = await _picker.pickImage(source: ImageSource.camera);

Answer 1

you can do so by adding the following after user finishes picking up image:

SystemChrome.setPreferredOrientations(DeviceOrientation.portraitUp);
