# Facematch and Liveness

## Facematch

### The method use to Start Facematch is

```
AccuraFacematch.startFaceMatch(accuraConfs)
```

In above method accuraConfs is an array consist of Face Uri in String Format, value will be provided by MRZ or OCR response.

```
var accuraConfs = [
{"face_uri":faceMatchURL}
];
```

### Methods use to set Facematch configs are as follows

```
    AccuraFacematch.setFaceMatchFeedbackTextSize(18);
    AccuraFacematch.setFaceMatchFeedBackframeMessage("Frame Your Face");
    AccuraFacematch.setFaceMatchFeedBackAwayMessage("Move Phone Away");
    AccuraFacematch.setFaceMatchFeedBackOpenEyesMessage("Keep Your Eyes Open");
    AccuraFacematch.setFaceMatchFeedBackCloserMessage("Move Phone Closer");
    AccuraFacematch.setFaceMatchFeedBackCenterMessage("Move Phone Center");
    AccuraFacematch.setFaceMatchFeedbackMultipleFaceMessage("Multiple Face Detected");
    AccuraFacematch.setFaceMatchFeedBackFaceSteadymessage("Keep Your Head Straight");
    AccuraFacematch.setFaceMatchFeedBackLowLightMessage("Low light detected");
    AccuraFacematch.setFaceMatchFeedBackBlurFaceMessage("Blur Detected Over Face");
    AccuraFacematch.setFaceMatchFeedBackGlareFaceMessage("Glare Detected");
    AccuraFacematch.setFaceMatchBlurPercentage(80);
    AccuraFacematch.setFaceMatchGlarePercentage_0(-1);
    AccuraFacematch.setFaceMatchGlarePercentage_1(-1);
```

### The example function is shown below

```
Future<void> startFaceMatch() async{
SystemChrome.setPreferredOrientations([DeviceOrientation.portraitUp]);
try{
var accuraConfs = {
  "face_uri":this.faceMatchURL
};

   await AccuraFacematch.setFaceMatchFeedbackTextSize(18);
   await AccuraFacematch.setFaceMatchFeedBackframeMessage("Frame Your Face");
   await AccuraFacematch.setFaceMatchFeedBackAwayMessage("Move Phone Away");
   await AccuraFacematch.setFaceMatchFeedBackOpenEyesMessage("Keep Your Eyes Open");
   await AccuraFacematch.setFaceMatchFeedBackCloserMessage("Move Phone Closer");
   await AccuraFacematch.setFaceMatchFeedBackCenterMessage("Move Phone Center");
   await AccuraFacematch.setFaceMatchFeedbackMultipleFaceMessage("Multiple Face Detected");
   await AccuraFacematch.setFaceMatchFeedBackFaceSteadymessage("Keep Your Head Straight");
   await AccuraFacematch.setFaceMatchFeedBackLowLightMessage("Low light detected");
   await AccuraFacematch.setFaceMatchFeedBackBlurFaceMessage("Blur Detected Over Face");
   await AccuraFacematch.setFaceMatchFeedBackGlareFaceMessage("Glare Detected");
   await AccuraFacematch.setFaceMatchBlurPercentage(80);
   await AccuraFacematch.setFaceMatchGlarePercentage_0(-1);
   await AccuraFacematch.setFaceMatchGlarePercentage_1(-1);

   await AccuraFacematch.startFaceMatch([accuraConfs])
    .then((value) => {
  setState((){
    dynamic result = json.decode(value);
        })
      }).onError((error, stackTrace) => {
     });
   }on PlatformException{}
}

## Liveness

### The method use to Start Liveness is

```
AccuraLiveness.startLiveness(accuraConfs)
```

In above method accuraConfs is an array consist of Face Uri in String Format, value will be provided by MRZ or OCR response.

```
var accuraConfs = [
  {"face_uri":faceMatchURL}
];
```

### Methods use to set Liveness configs are as follows

```
