Code to reproduce:

  void _initializeController() {
    if (cameras.length == 0) {
      log('No cameras detected');
      return;
    }
    controller = CameraController(cameras[0], ResolutionPreset.max,
        imageFormatGroup: Platform.isIOS ? ImageFormatGroup.bgra8888 : ImageFormatGroup.jpeg);

    controller.initialize().then((_) async {
      if (!mounted) {
        return;
      }
      try {
           await controller.setFlashMode( FlashMode.always);
      } catch (exc, stack) {

      }
      setState(() {});
    });
  }



  Future<String> takePicture() async {
    if (!controller.value.isInitialized) {
       return null;
    }
    if (controller.value.isTakingPicture) {
      return null;
    }
    try {
      final result = await controller.takePicture();
      return result.path;
    } catch (exc) {
      return null;
    }
  }
