void launchSNSMobileSDK() async {

  final String apiUrl = "https://test-api.sumsub.com"; // https://api.sumsub.com
  final String accessToken = "your access token";

  final onTokenExpiration = () async {
    // call your backend to fetch a new access token (this is just an example)
    Future<String>.delayed(Duration(seconds: 2), () {
      return "_act-66d142f3-88c1-4af6-ae6e-38578cc21c97";

  final SNSStatusChangedHandler onStatusChanged = (SNSMobileSDKStatus newStatus, SNSMobileSDKStatus prevStatus) {
    print("The SDK status was changed: $prevStatus -> $newStatus");

  final snsMobileSDK = SNSMobileSDK.Builder(apiUrl)
    .withAccessToken(accessToken, onTokenExpiration)
    .withHandlers(onStatusChanged: onStatusChanged)

  final SNSMobileSDKResult result = await snsMobileSDK.launch();

  print("Completed with result: ${result}");

The return type of the snsMobileSDK.launch() method is the Future of SNSMobileSDKResult type. Use it to determine the sdk status at the moment it has been closed.

Here is an example of the result:

  success: false,
  status: SNSMobileSDKStatus.Failed,
  errorType: SNSMobileSDKErrorType.Unauthorized,
  errorMsg: "Unauthorized access with accessToken=[your access token]"
