My camera class.

class CameraState extends State<Camera> with WidgetsBindingObserver {
  CameraController controller;
  List<CameraDescription> cameras;

  @override initState() {
    super.initState();
    getCameras();

    cameras.forEach((camera) {
      if (camera.lensDirection == CameraLensDirection.front) {
        onNewCameraSelected(camera);
      }
    });
  }

  /// Returns a suitable camera icon for [direction].
  IconData getCameraLensIcon(CameraLensDirection direction) {
    switch (direction) {
      case CameraLensDirection.back:
        return Icons.camera_rear;
      case CameraLensDirection.front:
        return Icons.camera_front;
      case CameraLensDirection.external:
        return Icons.camera;
    }
    throw ArgumentError('Unknown lens direction');
  }

Also tried almost all solutions on this thread but no luck.

I had crash with camera takepicture function.

For me helped adding
await controller.lockCaptureOrientation() after initialize().
Try this, maybe it will help you

   try {
          ///
          /// APP CRASHES HERE.
          /// 
          await controller.initialize();
          await controller.lockCaptureOrientation();

        }
