Flutter dynamic screen rotation - flutter

Question

What is the best way to dynamically do screen rotation in Flutter for few of the screens and not affect to other screens?
So i tried two ways, with mixins. (This way stackoverflow ). It works initially, for the first enter and leave screen, but when I do re-run again some of screen which should be landscape again, it's fixed in portrait and thats all, until i re-run the app.
And tried directly, with setting preferred orientation. (This way stackoverflow This way mess-up whole app even if i just unlock rotation on build/initState (tried both) on one screen, and lock it on same screen on dispose.
For example, i need camera screen rotated with whole UI, and i have screen to edit the image, and i need that screen in the portrait, and there problems shows up.
UPDATE: So here is the link with code with mixins try. I created mixin which enables rotation in that screen, and on dispose, lock rotation again. CODE
And code here:
mixin RotationEnabledStatefulModeMixin<T extends StatefulWidget> on
State<T> {
#override
Widget build(BuildContext context) {
_enableRotation();
return null;
}
#override
void dispose() {
_portraitModeOnly();
print("RotationEnabledStatefulModeMixin -> disposed!");
}
}
void _portraitModeOnly() {
SystemChrome.setPreferredOrientations([
DeviceOrientation.portraitUp,
DeviceOrientation.portraitDown,
]);
}
void _enableRotation() {
SystemChrome.setPreferredOrientations([
DeviceOrientation.portraitUp,
DeviceOrientation.portraitDown,
DeviceOrientation.landscapeLeft,
DeviceOrientation.landscapeRight,
]);
}
//this is screen where i need landscape only
class TakePictureScreen extends StatefulWidget {
final CameraDescription camera;
TakePictureScreen(
{Key key, #required this.camera, this.report, this.sectionIndex})
: super(key: key);
#override
TakePictureScreenState createState() => TakePictureScreenState();
}
class TakePictureScreenState extends State<TakePictureScreen> with
RotationEnabledStatefulModeMixin<TakePictureScreen>{
CameraController _controller;
#override
void initState() {
super.initState();
}
#override
Widget build(BuildContext context) {
super.build(context);
}
#override
void dispose() {
_controller.dispose();
super.dispose();
}
}
