I just finished the first video and I get an error relating to firebase #4
Comments
Yes I did but now I am having a different problem. My app does start the connection to Firebase but each time it says connection timed out and I cannot resolve it. |
@theindianappguy do you use stream in this app? If we want to launch this app is there anyway to do this without stream?? |
Hello Akshay, |
The easiest way to solve this issue is to add those lines at your import 'package:flutter_chat_app/helper/authenticate.dart';
import 'package:firebase_core/firebase_core.dart';
void main() async {
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp();
runApp(MyApp());
} |
