Object.noSuchMethod getOfferings

[tecbot]

Hey,

if there are no offerings available the current parsing of getOfferings will throw an exception.
We found also that this can happen in production, why we are not sure, possible network issue? If a network error could lead to this as well then this is a second issue because I expect that the native plugin throws a PlatformException with NetworkError code.

Non-fatal Exception: dart:core-patch/object_patch.dart 53 in Object.noSuchMethod
0  ???                            0x0 Object.noSuchMethod + 53 (object_patch.dart:53)
1  ???                            0x0 new Offering.fromJson + 37 (offering_wrapper.dart:37)
2  ???                            0x0 new Offerings.fromJson + 13 (offerings_wrapper.dart:13)
3  ???                            0x0 Purchases.getOfferings + 108 (purchases_flutter.dart:108)

We use version: 1.0.1 of the plugin and Flutter (Channel beta, v1.12.13+hotfix.6)

Thanks for reporting this. I just released https://github.com/RevenueCat/purchases-flutter/releases/tag/1.0.3 which should address this issue.

I wasn't able to reproduce it when not having connectivity, and it still reported a PlatformException with a NetworkError but hopefully you stop seeing it in production too, not sure how it could happen though...

@vegaro thx for the quick fix. We had added in production a retry mechanism if we get empty offerings, unfortunately without luck. We get also after 10 attempts with backoff empty offerings. It doesn't happen often comparing to our user base but the root cause would be good to figure out. Network connection is working on the device. What could lead to this behavior?
