设置通知侦听器

介绍如何使用云眼灰度实验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) });
