Onesignal-flutter-sdk: How to wait for player ID to initialize?

Created on 28 Aug 2020 · 8Comments · Source: OneSignal/OneSignal-Flutter-SDK

Description:

Good day! A situation has arisen when the playerID does not have time to be initialized at the moment when it is already needed. How to wait for its initialization?

Environment

Flutter 1.20.2 • channel stable • https://github.com/flutter/flutter.git
Framework • revision bbfbf1770c (2 weeks ago) • 2020-08-13 08:33:09 -0700
Engine • revision 9d5b21729f
Tools • Dart 2.9.1

Steps to Reproduce Issue:

Install the OneSignal Flutter SDK using pub into your project.
Initialize the SDK using OneSignal.shared.init(your_app_id).
Try to get playerID right away:

final status = await _oneSignal.getPermissionSubscriptionState();
final playerId = status.subscriptionStatus?.userId;

PlayerID will be NULL until a request is sent to https://api.onesignal.com/players

Howdy,
The best way to do this is to wait until the subscription observer fires.

Hope that helps!

And how do I wait for the subscription observer to fire?

@rgomezp, this didn't solve my problem. I want to keep the application at the moment of showing the splash screen, waiting for the playerId to be initialized. It works correctly on Android, the problem is only on iOS.

Nothing prevents me from using a listener, but just initializing the OneSignal instance works differently depending on the platform. On Android, playerId is waiting for initialization, but not on iOS.

@Holofox I am wondering how were you able to fix this issue?
