The argument type 'void Function(Map<String, dynamic>)' can't be assigned to the parameter type 'void Function(ActionResponse)

[kunzig940]

Running the example code results in the subject error:

The argument type 'void Function(Map<String, dynamic>)' can't be assigned to the parameter type 'void Function(ActionResponse)

final onMessageCallback = ActionCallback( name: 'on_receive_message', callback: onReceiveMessage, );

void onReceiveMessage(Map<String, dynamic> data) { final message = data['data']['message']; debugPrint(message); }

Morning @kunzig940,

To test this effectively, I'd need to connect to a server. Do you have one available? Otherwise, I'll need to spin one up myself, which might take some time.

---

I'll hold off on updating the project constraints (Flutter version, Dart SDK, and package dependencies) until I have a server environment set up for testing.

I'm currently running it on a local server else I'd def share! I ran the example code in the docs but it errors like above unless I change the object passed to receiveMessage to dynamic at which point it provides an ActionResponse object instead of a map but with no data.

If I don't add the method name used in the callback to the broadcast from my server over ActionCable, the debug logs (posted below) do show the data is making it from the server over actionable to flutter but I can't access the data object at that point since it'd require reverting the receiveMessage function to accepting a Map instead of dynamic. Any help would be greatly appreciated! Thanks.

The snapshot below shows the issue. It's expecting ActionResponse instead of a Map<String,Dynamic> for a callback.

Sorry for delay.

I tried to run a local rails server in my linux machine but without a success :( I'm new in linux

I'm trying to guess what is going on with this problem, but without a server idk if I will help

No worries but thanks for looking into it. Currently using the older flutter pckg. atm.
