Receive a device token
Push notifications are delivered to your user's devices through a device token which uniquely identifies your app. Although Amplify will automatically register this token with Amazon Pinpoint, it can still be useful to have access to this token for your app's use cases (e.g. to send direct notifications to a specific device).
onTokenReceived
Add onTokenReceived
listeners to respond to a token being received by your app.
A token will be received by your app:
- On every app launch, including the first install
- When a token changes (this may happen if the service invalidates the token for any reason)
void myTokenReceivedHandler(String token) { // Do something with the received token}
final subscription = Amplify.Notifications.Push.onTokenReceived .listen(myTokenReceivedHandler);
// Remember to cancel the subscription when it is no longer neededsubscription.cancel();
