Calling listUsers throws "Cannot be converted to a deep immutable object: Instance of 'GoogleCloudIdentitytoolkitV1ProviderUserInfo’"

[livtanong]

Running under Windows.

The class definition for GoogleCloudIdentitytoolkitV1ProviderUserInfo cannot be found in firebase_admin. Instead it can be found in a dependency: https://github.com/invertase/dart_firebase_apis/blob/541a555ac378f7fadfdd404f5de04e6898da9523/generated/firebaseapis/lib/identitytoolkit/v1.dart#L3996

Seems like firebase_admin is unexpectedly getting this class rather than raw json data for deserialization.

I think I've found the root cause, and it's an incomplete implementation of GoogleCloudIdentitytoolkitV1UserInfo.toJson. I have filed an issue in the library.

invertase/dart_firebase_apis#6

Turns out that this is by design. The workaround would be for firebase_admin to replace the .toJson() call with: jsonDecode(jsonEncode(u))
This is of course less efficient, but at least it will be "correct".

Context: dart_firebase_apis is based on googleapis.dart.
google/googleapis.dart#438
