SDK API reference

The SDK API provides the following methods with their signatures, parameters, and usage examples.

Get user consent. Calling this API generates a user ID and initiates tracking.

Call optIn after start.

await CSQ().optIn();

No parameters.

Revoke user consent, remove stored userID. Stop CSQ SDK, flush, and clear all data.

await CSQ().optOut();

No parameters.

Product Analytics | Ajouté à la version : 1.0.0

Assigns an identity to be associated with the current user.

This assigns the identity to all events for the user ID and lets the analysis module merge multiple user IDs with the same identity.

This should be called only after Product Analytics is configured and the SDK started. It's safe to call multiple times with the same value. Always provide a value that will be unique to this user. Setting values like "guest", "anonymous", "unauthenticated" or similar will merge all those users into a single user profile.

await CSQ().identify(userIdentifier: 'userIdentity');

• userIdentifier   String (<= 100 chars)  

  Identity to be associated with the current user.

If the user was previously identified with identify(), this creates a new unidentified user and session. This is technically similar to calling optOut() then optIn().

This should be called only after Product Analytics is configured and the SDK started.

await CSQ().resetIdentity();

No parameters.

Get all the information related to the user and project.

Identifier of the current user.

final userId = CSQ().metadata.userId;

Session identifier. This is an identifier from Experience Analytics by default or Product Analytics if Experience Analytics is not active.

final sessionId = CSQ().metadata.sessionId;

Project identifier for Experience Analytics.

final projectId = CSQ().metadata.projectId;

Environment identifier for Product Analytics.

final environmentId = CSQ().metadata.environmentId;

URL of current Session Replay.

final sessionReplayUrl = CSQ().metadata.sessionReplayUrl;

Identity associated with the user by calling identify().

final identity = CSQ().metadata.identity;

Listen for changes to user metadata. For example when sessionReplayUrl becomes available or userId updates.

final subscription = CSQ().metadata.onChange((metadata) {
  // Handle information change
});

// Cancel when no longer needed
subscription.cancel();

• handler   void Function(Metadata metadata)  

  Callback triggered whenever metadata changes. Called immediately with current metadata if available.

Sets the current log level.

await CSQ().debug.setLogLevel(LogLevel.debug);

• logLevel   Enum (LogLevel)  

  Possible values: all, trace, debug, info, warning, error, important, or none.

Experience Analytics | Ajouté à la version : 1.0.0

Adds dynamic variables to the session properties. This method allows you to pass DynamicVar objects, representing key-value pairs that are scoped to the session.

final var1 = DynamicVar.fromString(key: 'key1', value: 'value1');
final var2 = DynamicVar.fromInt(key: 'key2', value: 2);

await CSQ().addDynamicVar(var1);
await CSQ().addDynamicVar(var2);

• dynamicVar   DynamicVar  

  The dynamic variable

  key   String (<= 50 chars)  

  Dynamic variable key

  value   int or String  

  Dynamic variable value. Use DynamicVar.fromInt for integer values (0 to 2³² - 1) or DynamicVar.fromString for string values (<= 255 chars).

Product Analytics | Ajouté à la version : 1.0.0

Add a collection of properties to be associated with the current user.

await CSQ().addUserProperties(properties: {'propertyKey': 'propertyValue'});

• properties   Map<String, dynamic>  

  A map of user properties. Supported value types: String, num, bool. All other types will be ignored.

Product Analytics | Ajouté à la version : 1.0.0

Add a collection of properties to be associated with all future events.

await CSQ().addEventProperties(properties: {'propertyKey': 'propertyValue'});

• properties   Map<String, dynamic>  

  A map of event properties. Supported value types: String, num, bool. All other types will be ignored.

Product Analytics | Ajouté à la version : 1.0.0

Removes a single property from the collection of event-wide properties.

await CSQ().removeEventProperty(name: 'propertyKey');

• name   String  

  The key of the property to remove.

Product Analytics | Ajouté à la version : 1.0.0

Removes all event-wide properties.

await CSQ().clearEventProperties();

Experience Analytics | Ajouté à la version : 1.0.0

Widget that enables CSQ tracking inside a WebView. Wrap your WebView widget with CSQWebViewWrapper and pass a delegate that supplies the WebView.

To enable WebView support, you must also implement the CSQ WebView JavaScript Tracking Tag in the web pages loaded by the WebView.

Two delegate types are available depending on your WebView package:

• UserScriptWebViewWrapperDelegate — for packages like flutter_inappwebview that support user scripts
• JSChannelWebViewWrapperDelegate — for packages like webview_flutter that use JavaScript channels

// Using UserScriptWebViewWrapperDelegate (for example flutter_inappwebview)
CSQWebViewWrapper(
  delegate: UserScriptWebViewWrapperDelegate(
    builder: (context, userScript) {
      return InAppWebView(
        initialUserScripts: UnmodifiableListView([
          UserScript(
            source: userScript,
            injectionTime: UserScriptInjectionTime.AT_DOCUMENT_START,
          ),
        ]),
      );
    },
  ),
)

// Using JSChannelWebViewWrapperDelegate (for example webview_flutter)
CSQWebViewWrapper(
  delegate: JSChannelWebViewWrapperDelegate(
    addJavaScriptChannel: (handler) {
      webViewController.addJavaScriptChannel(
        handler.channelName,
        onMessageReceived: (jsMessage) {
          handler.onMessageReceived(jsMessage.message);
        },
      );
    },
    builder: (context) => WebViewWidget(controller: webViewController),
  ),
)

• delegate   WebViewWrapperDelegate  

  The delegate that supplies the WebView widget to be wrapped.
