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, I recommend checking out this StackOverflow thread: https://stackoverflow.com/questions/63492211/no-firebase-app-default-has-been-created-call-firebase-initializeapp-in There's more info on why this happened in the thread. I used the fourth method because it was an easy implementation and it solved this issue instantly.
The easiest way to solve this issue is to add those lines at your main.dart
-file in your main
-function
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());
}
