I need to take token before but I can using await into initState

do you have any advise?

@override
    void initState() {
      super.initState();
       final _storage = new FlutterSecureStorage();
       String token = await _storage.read(key: 'token');    // <--- 

      _cable = ActionCable.Stream(_action_cable_url, {HttpHeaders.authorizationHeader: token}); // <---
      _cable.stream.listen((value) {
        if (value is ActionCableConnected) {
          print('ActionCableConnected');
          _cable.subscribeToChannel(_channel, channelParams: {'id': 10});
        } else if (value is ActionCableSubscriptionConfirmed) {
          print('ActionCableSubscriptionConfirmed');
          _cable.performAction(_channel, 'send_message',
              channelParams: {'id': 10}, actionParams: {'body': 'hello world'});
        } else if (value is ActionCableMessage) {
          print('ActionCableMessage ${jsonEncode(value.message)}');
        }
      });
    }
