Firestore GeoPoint Type

[pauldemarco]

Similar to issue #12437, the Firestore plugin should convert GeoPoint data types from the store to an official Dart type, if one exists.

GeoPoint Reference Firestore Data Types

I don't think we have a defined type for this yet, but we could create one.

Is this a request for the Dart team? Should we move it over to the Dart SDK?

This would just be a trivial type (class with two final doubles) in the plugin.

Ah, I see. Thanks. Would we accept a PR for it?

Looks like this issue will cause the app to crash with the following exception:

Unsupported value: <FIRGeoPoint: (59.583559, 11.167059)> of type FIRGeoPoint
*** Assertion failure in -[FlutterStandardWriter writeValue:], ../../flutter/shell/platform/darwin/ios/framework/Source/FlutterStandardCodec.mm:321

(just some added context in case anyone is Googling for a solution to the above error)

The fork mentioned in this PR https://github.com/flutter/plugins/pull/343 works for me for now :) seems close to merging

Can be closed, via flutter/plugins#429
