Initialize SDK and get device details
To initialise the SDK add the below line of code with the public key you retrieved from Sense client panel. If you don't have a public key create new one and call that below function.
1. Signal SDK
The Signal SDK collects device and browser information and sends it to the Sense Server for risk analysis. It also generates a unique sense_id for device identification and tracking.
2. Behaviour SDK
The Behaviour SDK analyzes user interactions such as keystrokes, touch events,scrolling patterns, and more. The collected behaviour data is sent to the Sense Server to receive behaviour analysis results and risk insights.
How to Install
1.1. Add Dependency in pubspec.yaml
Add both Device Security and Behaviour Dependency in pubspec.yaml
sense_flutter_plugin : 2.0.1 // signal
sense_behaviour_flutter_plugin : 0.0.1 //Behaviour1.2. Import Package
import 'package:sense_flutter_plugin/sense_flutter_plugin.dart';
import 'package:sense_behaviour_flutter_plugin/sense_behaviour_flutter_plugin.dart';1.3. Initialize SDK
Add the following line of code to initialize it with the api key you obtained from the Sense Client panel.
//For Device Security
Sense.initSDK({
"publicKey": "YOUR_PUBLIC_KEY",
"senseInfo": true,
"allowGeoLocation": false,
"tag": "HomeFlutter"
});
Sense.getSenseDetails();
//For Behavior SDK
SenseBehaviourRoot(
child: MyApp(), // Your App Widget
),
SenseBehaviourFlutter.initSDK(
apiKey: 'YOUR_PUBLIC_KEY',
sense_request_id : "SENSE_REQUEST_ID", // Your request id you get from the Sense Device Security SDK
context: context,
inputControllers: [ // Your input controllers
nameController,
colorController,
],
);1.4. Sample Program
Here you can find the demonstration to do the integration.
//For Behavior SDK - App Widget
SenseBehaviourRoot(
child: MyApp(), // Your App Widget
),
