title: Flutter camera plugin prevent orientation change?
body: <p>Using the latest version <code>0.8.1</code>, is there a way to prevent orientation change? I have locked the device orientation using <code>SystemChrome.setPreferredOrientations([DeviceOrientation.portraitUp]);</code> but if I rotate the device to landscape, the camera also attempts to rotate and the preview looks compressed. A good example would be the instagram camera, which is locked to portrait mode. If you rotate your device the preview doesn't move at all.</p>
