Can I check if user is subscribed on flutter web app?

Hey @Mike Jones ,

If your users have the same user ID, then the subscriptions will be shared across multiple platforms and all you will need to do is call getCustomerInfo() to access if they have a subscription or not. 

More information on checking if they have an active subscription can be found here: https://www.revenuecat.com/docs/customer-info#get-user-information

 @Mike Jones: Below is a code snippet that I am using on web, which simply goes via the API rather than the Flutter SDK.

  Future<bool> _getSubscriptionStatusWeb(User user) async {
    bool hasActiveSubscription = false;
    try {
      Uri uri = Uri.https('api.revenuecat.com', '/v1/subscribers/${user.id!}');
      await http.get(uri, headers: {
        'Content-Type': 'application/json',
        'Authorization': 'Bearer $revenueCatApiKey',
      }).then((response) {
        if (response.statusCode == 200) {
          Map<String, dynamic> customerInfo = json.decode(response.body);
          Map<String, dynamic> entitlements =
              customerInfo['subscriber']['entitlements'];
          if (entitlements.isNotEmpty) {
            List<DateTime?> expiryDates = entitlements.values
                .map((entitlement) =>
                    DateTime.tryParse(entitlement['expires_date']))
                .toList();
            hasActiveSubscription = expiryDates.firstWhereOrNull(
                    (element) => element!.isAfter(DateTime.now())) !=
                null;
          }
        }
      });
    } catch (e) {
      debugPrint("Unable to retrieve subscriber status from Revenuecat");
    }
    return hasActiveSubscription;
  }

@Mike Jones - I’m not sure I understand the issue. The code snippet is written in dart and simply queries a web api. This will work regardless of any platform, as long as you have an internet connection.

@Matt I went to implement this today and got these errors:

Undefined name 'http'.

and

The method 'firstWhereOrNull' isn't defined for the type 'List'.
Try correcting the name to the name of an existing method, or defining a method named 'firstWhereOrNull'.

Assuming $revenueCatApiKey I just replace with my api key? And User user I can change to a string to my user ids?
