Does this package work on Flutter Web

[tomrobinsonv]

Hi, we're trying to implement GCloud Pubsub on Web but running into an issue on initialisation where it is trying to find the Platform._environment which is unsupported on Web. Just wanted some clarification on this as I can't find much information on this anywhere.

Dart Version: 2.18.6
Flutter Version: 3.3.10
GCloud Version: ^0.8.7
Google APIS Auth: ^1.3.1

This is the error I get when trying to create PubSub Instance.

I have managed to get this working by manually going into the pubsub.dart file and removing the Platform.environment check which was causing the issue. It seems like this is all that's blocking it on web and it's only there check wether it is running on an emulator or not. Is it possible to get this removed or just add a check like
{ if(kIsWeb) check emulator }

, so it can work on web.

This is the code I changed.

factory PubSub(http.Client client, String project) { var emulator = Platform.environment['PUBSUB_EMULATOR_HOST']; return emulator == null ? _PubSubImpl(client, project) : _PubSubImpl.rootUrl(client, project, 'http://$emulator/'); }
to this

factory PubSub(http.Client client, String project) { return _PubSubImpl(client, project); }
