setUserId method

@override Future<void> setUserId(String userId, BeamsAuthProvider provider, OnUserCallback callback)

Sets authentication for this device, so you can send notifications specifically for this device. You must create a BeamsAuthProvider in order to pass the provider argument.

Example Usage

function someAsyncFunction() async {
  final BeamsAuthProvider provider = BeamsAuthProvider()
    ..authUrl = 'https://some-auth-url.com/secure'
    ..headers = {
      'Content-Type': 'application/json'
    }
    ..queryParams = {
      'page': '1'
    }
    ..credentials = 'omit';

  await PusherBeams.instance.setUserId('THIS IS AN USER ID', provider, (error) => {
    if (error != null) {
      print(error)
    }

    // Success! Do something...
  });
}
