I am developing an app in flutter I am using firebase in this app. And I am using following dependencies:
firebase_messaging: ^10.0.0
firebase_core: ^1.2.0
cloud_firestore: ^2.2.0
firebase_storage: ^8.1.0
I am initializing firebase like this:
void main() async {
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp();
runApp(MyApp());
}
This whole code was working fine till today's morning but after that it is giving this error everytime:

Is there anything wrong with android studio or flutter SDK itself? I have also noticed that there is one file generated that was not there earlier when the app was working fully functional the file is named "generated_plugin_registrant.dart".
Update:
I removed flutter from my windows and again installed it but it didn't work as well. Now I think I should uninstall android studio completely and again install it because I don't find any error or wrong implementation in my code till now, Please tell me if there is any.
Please help me.
Thanks for your replies.

I searched a lot on the internet but the solution was very simple. It was happening because the following code was missing in my MainActivity.kt.\nCode:\noverride fun configureFlutterEngine(@NonNull flutterEngine: FlutterEngine) {\nGeneratedPluginRegistrant.registerWith(flutterEngine); }\nIt was not registering the flutter plugins that's why it was giving an error it took me 2 and a half days I hope if someone else is facing this issue they can solve it earlier than me.\nAnd thanks for all your replies.",

I had the same problem. I also tried many solution like you, but could not able to resolve it issues.\nLatter, I ended up creating a new project carefully copying firebase and multiple other packages from the original project. After that I copied every single file in lib/android along with their respective configurations in build.gradle and manifests. For iOS I just copied the entire project and that worked immediately.\nYou also can try like my. Create a new project and copy everything from your old project to new one, one by one to see this issue resolved or not.",
