How do I implement an opt-in consent system for push notifications and tracking in my Flutter app?

To comply with privacy regulations such as GDPR, you can start the Pushwoosh SDK in a disabled state and only enable communication and tracking after the user gives explicit consent. This requires pushwoosh_flutter version 2.3.14 or newer (the version that added the server-communication methods).

1. Disable server communication by default

Prevent the SDK from talking to Pushwoosh servers at app start by adding a native configuration flag.

Android — in AndroidManifest.xml, inside the <application> tag:

<meta-data android:name="com.pushwoosh.allow_server_communication" android:value="false" />

iOS — in Info.plist:

• Key: Pushwoosh_ALLOW_SERVER_COMMUNICATION
• Type: Boolean
• Value: NO

2. Enable communication after consent (opt-in)

In Dart, Pushwoosh.getInstance is a getter, not a method — do not write getInstance().

// When the user opts in
// 1. Start communication with Pushwoosh servers
Pushwoosh.getInstance.startServerCommunication();

// 2. Register the device for push notifications
await Pushwoosh.getInstance.registerForPushNotifications();

3. Disable communication if consent is revoked (opt-out)

Unregister the device before stopping communication, otherwise the unregistration request never reaches Pushwoosh. unregisterForPushNotifications() returns a Future, so await it.

// When the user opts out
// 1. Unregister the device from push notifications
await Pushwoosh.getInstance.unregisterForPushNotifications();

// 2. Only then stop all communication
Pushwoosh.getInstance.stopServerCommunication();

Keeping the plugin on a current release is recommended; check pub.dev for the latest pushwoosh_flutter version.
