Polygon property returned as Null for the Flutter SDK

[alexvenom]

Issue Description

For any given Class containing a Polygon type property correctly set with GeoPoints, when queried through the Flutter SDK the property will be retrieved as null. Other SDKs will retrieve the property correctly displaying all GeoPoints that form the Polygon.

Steps to reproduce

• Create a Class with a Polygon property
• Add valid GeoPoints to the Polygon property (at least 3 GeoPoints)
• Query the created Class using the Flutter SDK
• Observe the Polygon property is returned as null

Actual Outcome

Actual print of the ParseObject containing a valid Polygon property named "square", returned as Null by the Flutter SDK:

{"className":"Georef","objectId":"HjR3l1cHV4","createdAt":"2022-07-25T17:04:15.276Z","updatedAt":"2022-07-25T17:29:33.128Z","square":null,"name":"Test"}

Here the output of the same object using the JS SDK:

{"square":{"__type":"Polygon","coordinates":[[0,0],[0,1],[1,1],[1,0],[0,0]]},"createdAt":"2022-07-25T17:04:15.276Z","updatedAt":"2022-07-25T17:29:33.128Z","name":"Test","objectId":"HjR3l1cHV4"}

Expected Outcome

The "square" property on the output above should contain a List<ParseGeoPoint> or similar data representing the Polygon

I tested your instructions, there was no problem in terms of getting Polygon. Did you include it?

I'll go ahead and close this as it wasn't reproducible. @alexvenom We can reopen this issue if you could post a sample code to reproduce it.
