retry method

Implementation

Future<void> retry() async {
  _pendingCaptureRequest = false;

  state = state.copyWith(
    state: LivenessState.initial,
    sessionState: LivenessSessionState.initializing,
    errorMessage: null,
    session: null,
  );

  await Future.delayed(const Duration(milliseconds: 100));
  await startLivenessCapture();
}
