1. Usage of FacesdkPlugin

Activate the FacesdkPlugin

To activate the FacesdkPlugin, use the setActivation method with your activation key:

final _facesdkPlugin = FacesdkPlugin();
...
await _facesdkPlugin
    .setActivation(
        "Os8QQO1k4+7MpzJ00bVHLv3UENK8YEB04ohoJsU29wwW1u4fBzrpF6MYoqxpxXw9m5LGd0fKsuiK"
        "fETuwulmSR/gzdSndn8M/XrEMXnOtUs1W+XmB1SfKlNUkjUApax82KztTASiMsRyJ635xj8C6oE1"
        "gzCe9fN0CT1ysqCQuD3fA66HPZ/Dhpae2GdKIZtZVOK8mXzuWvhnNOPb1lRLg4K1IL95djy0PKTh"
        "BNPKNpI6nfDMnzcbpw0612xwHO3YKKvR7B9iqRbalL0jLblDsmnOqV7u1glLvAfSCL7F5G1grwxL"
        "Yo1VrNPVGDWA/Qj6Z2tPC0ENQaB4u/vXAS0ipg==")
    .then((value) => facepluginState = value ?? -1);  

---

Initialize FacesdkPlugin

Before using the SDK, initialize it with the init method:

await _facesdkPlugin
    .init()
    .then((value) => facepluginState = value ?? -1);

---

Set Parameters

Configure the SDK settings using setParam:

await _facesdkPlugin
    .setParam({'check_liveness_level': livenessLevel ?? 0});

---

Extract Face Features

Use the extractFaces method to detect and extract face features from an image:

final faces = await _facesdkPlugin.extractFaces(image.path);

---

Calculate Face Similarity

Compare two face templates and calculate their similarity score:

double similarity = await _facesdkPlugin.similarityCalculation(
    face['templates'], person.templates) ?? -1;

2. Working with camera stream
