Utilização

FaceLiveness faceLiveness =
        FaceLiveness(mobileToken: mobileToken, peopleId: personId);

// Your SDK customization parameters

final stream = faceLiveness.start();

    stream.listen((event) {

      if (event is FaceLivenessEventConnecting) {
        // The SDK is connecting to the server. You should provide an indeterminate progress indicator
        // to let the user know that the connection is taking place.
      } else if (event is FaceLivenessEventConnected) {
        // The SDK has connected, and the iProov user interface will now be displayed. You should hide
        // any progress indication at this point.
      } else if (event is FaceLivenessEventClosed) {
        // The user canceled face verification, either by pressing the close button at the top of the screen, or sending
        // the app to the background.
      } else if (event is FaceLivenessEventSuccess) {
        // The user was successfully verified/enrolled and the token has been validated.
        // You can access the following properties:
        final signedResponse = event.signedResponse;
      } else if (event is FaceLivenessEventFailure) {
        // The user was not successfully verified/enrolled, as their identity could not be verified,
        // or there was another issue with their verification/enrollment (e.g. lost internet connection).
        // You can access the following properties:
        final errorType = event.errorType
        final errorMessage = event.errorMessage
        final code = event.code
        final signedResponse = event.signedResponse
      }
    });
