void onInit()
override

Called immediately after the widget is allocated in memory. You might use this to initialize something for the controller.

Implementation

@override
void onInit() {
  WidgetsBinding.instance.addObserver(this);
  tabController = TabController(length: 3, vsync: this);
  if (cameras.isNotEmpty) {
    onNewCameraSelected(cameras[0]);
  }
  sensorStream = accelerometerEventStream()
      .map<DeviceOrientation>(Utils.getOrientation)
      .distinct();
  sensorStream.listen((event) {
    currentOrientation.value = event;
  });
  super.onInit();
}
