Frontend callback feature is released on May 26, 2022.

Introduction

Our SDK provides a callback after closing or submitting the survey by the user. For that you just need to add listener for oneFlowSurveyFinishNotification event which will get triggered as soon a user will submit the survey. In the below code, you will see how to implement a 1Flow survey callback in Flutter.

dart
void main() {
  runApp(MyApp());
  // Add this line to configure 1Flow
  OneFlow.configure('<1flow_project_key>',true); // true if want to enable surveys otherwise false.
 /* Adding 'oneFlowSurveyFinishNotificationHandler' event listener. 
	     This event will be triggered as soon as user will submit the survey. */
  OneFlow.methodchannel.setMethodCallHandler(oneFlowSurveyFinishNotificationHandler);
}


/* Event listener function which will be called 
   as soon as 'oneFlowSurveyFinishNotification' will be triggered. */
Future<void> oneFlowSurveyFinishNotificationHandler(MethodCall call) async {
    final String method = call.method;
    dynamic argument = call.arguments;
    switch (method) {
      case "oneFlowSurveyFinishNotification":
        {
          print("oneFlowSurveyFinishNotification: $argument");
        }
        break;
      default:
        {
          print("Invalid choice");
        }
        break;
    }
  }
