Analyzing the image to detect faces

Now, we analyze the image to detect faces. We will create an instance of the FirebaseVision face detector to detect the faces using the following steps:

1. First, we create a global faces variable inside the FaceDetectionState class, as shown in the following code:

List<Face> faces;

2. Now we define a detectFaces() method, inside which we instantiate FaceDetector as follows:

void detectFaces() async{    final FirebaseVisionImage visionImage = FirebaseVisionImage.fromFile(widget.file);    final FaceDetector faceDetector = FirebaseVision.instance.faceDetector(FaceDetectorOptions( mode:     FaceDetectorMode.accurate, enableLandmarks: true, enableClassification: true));    List<Face> detectedFaces = await faceDetector. ...
