Flutter Exception Error Creating StreamChat channel

Question

Hello I'm trying to use StreamChat.io API to build a chat app but when I try to create a channel I get this error StreamChatNetworkError (StreamChatNetworkError(code: 1000, message: Unauthorised, token not defined))

Here is the code I set to join a channel

Future<void> createChannel(BuildContext context) async {
try {
  final currentUser = FirebaseAuth.instance.currentUser;
  final userID = currentUser!.uid;
  final client = StreamChatCore.of(context).client;
  final channel = client.channel("messaging", id: userID, extraData: {
    "name": _name.text.trim(),
  });
  AccountUpdate.storeChannel(channel);
  await channel.watch();
  print("this is the channel output $channel");
} catch (e) {
  print(e);
}

} And I have disabled Auth checks so there is no need for a secret

With help from the Stream team, I figured out that you need to establish a connected user first in order to watch a channel

await client.connectUser(
    User(id: "john"),
    client.devToken('john').rawValue,
  );

EDIT: The above makes use of developer tokens (which requires authentication to be disabled). In a production environment you will need to generate frontend tokens using one of Stream's backend clients. Or for development purposes you can use the online token generator https://getstream.io/chat/docs/flutter-dart/token_generator/?language=dart
