设置通知侦听器

介绍如何使用云眼灰度发布(特性标帜)AB实验Flutter SDK 设置和删除通知侦听器。

通知侦听器会触发您在 SDK 基于某些操作触发时定义的回调函数。

最常见的用例是将所有灰度发布(特性标帜)决策的流发送到分析提供商或内部数据仓库,以将其与您拥有的有关用户的其他数据联接。

通知侦听器类型

有关通知侦听器类型和用例的更多信息,请参阅通知侦听器

有关代码示例,请参阅以下部分。

添加或删除所有通知侦听器

下面的示例代码演示如何添加侦听器和删除侦听器。

Dart

// Add Notification Listener (LogEvent) var logEventListenerId = await flutterSDK.addLogEventNotificationListener((logEvent) { print(logEvent.url); print(logEvent.params); }); // Remove Notification Listener await flutterSDK.removeNotificationListener(logEventListenerId); // Clear all notification listeners of a certain type await flutterSDK.clearNotificationsListeners(ListenerType.logEvent); // Clear all notifications await flutterSDK.clearAllNotificationListeners();

设置每种类型的通知侦听器

下面的示例代码演示如何设置每种类型的通知侦听器。

Dart

// SET UP DECISION NOTIFICATION LISTENER var decisionEventListenerId = await flutterSDK.addDecisionNotificationListener((notification) { // Access type on decisionObject to get type of decision var decisionType = notification.type; if (decisionType == "flag") { var flagDecisionInfo = notification.decisionInfo; var flagKey = flagDecisionInfo["flagKey"]; var enabled = flagDecisionInfo["enabled"]; var decisionEventDispatched = flagDecisionInfo["decisionEventDispatched"]; } // Send data to analytics provider here }); // SET UP LOG EVENT NOTIFICATION LISTENER var logEventListenerId = await flutterSDK.addLogEventNotificationListener((logEvent) { // process the logEvent object here (send to analytics provider, audit/inspect data) }); // SET UP EYEOFCLOUD CONFIG NOTIFICATION LISTENER var updateConfigListenerId = await flutterSDK.addConfigUpdateNotificationListener((configNotification) { var eyeofcloudConfig = flutterSDK.getEyeofcloudConfig(); }); // SET UP TRACK LISTENER var trackNotificationListenerId = await flutterSDK.addTrackNotificationListener((trackNotification) { // process the event here (send to analytics provider, audit/inspect data) });
