Please, any help would be appreciated and googling doesn't seem to be producing any proper solutions here. What confuses me even more is that this error now appears even when trying to run apps with no firebase or even async functions, making doing anything else in flutter essentially impossible for me now. I have been trying to learn firebase and have followed the steps as shown here without much issues. When googling the solution for the problem I am facing(error message at the end of the post), a common fix I have seen is adding just this line to the main function.
WidgetsFlutterBinding.ensureInitialized();
However I already have it and I still keep getting the same error again. Here is my void main function.
void main() async{
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp(
options: DefaultFirebaseOptions.currentPlatform,
);
runApp(const App());
}
Here is the error in question:
Launching lib\main.dart on sdk gphone x86 64 in debug mode...

What I find more concerning is that now none of my flutter projects work and all show the same error, even those which do not have firebase connected to them. At this point I am not even sure whether this is an issue with firebase or something else. I am not sure how to interpret this, but I hope someone more knowledgeable than me can help me understand.
Ok turns out all I had to do was upgrade flutter.
