When I try to run my flutter app on chrome, it crashes. It happens only after I installed Firebase_core and runs fine on Android or iOS. I am trying to connect my flutter web app, to the same Firebase Cloud, as my other app. I have follewed the instructions in the firebase console and added a new app. I tried adding a new web app, following the steps, and when that didn't work, I tried the same with adding a flutter app. (Here I talking about the firebase console).
I tried to initialize the app in my main file like this:
import "package:firebase_core/firebase_core.dart" as core;
void main() async {
WidgetsFlutterBinding.ensureInitialized();
await core.Firebase.initializeApp(
options: core.FirebaseOptions(
apiKey: "apiKey",
appId: "appId",
messagingSenderId: "messagingSenderId",
projectId: " projectId"
)
);
runApp(const MyApp());
}
And in my html I added this script to the body:
<script type="module">
// Import the functions you need from the SDKs you need
import { initializeApp } from "firebase/app";
import { getAnalytics } from "firebase/analytics";
// TODO: Add SDKs for Firebase products that you want to use
// https://firebase.google.com/docs/web/setup#available-libraries
// Your web app's Firebase configuration
// For Firebase JS SDK v7.20.0 and later, measurementId is optional
const firebaseConfig = {
apiKey: "my apikey",
authDomain: "my authDomain",
databaseURL: "databaseURL",
projectId: "projectId",
storageBucket: "storageBucket",
messagingSenderId: "messagingSenderId",
appId: "appId",
measurementId: "measurementId"
};
// Initialize Firebase
const app = initializeApp(firebaseConfig);
const analytics = getAnalytics(app);
</script>
My pubspec.yaml is very simple:
dependencies:
flutter:
sdk: flutter
# The following adds the Cupertino Icons font to your application.
# Use with the CupertinoIcons class for iOS style icons.
cupertino_icons: ^1.0.2
firebase_core: ^2.1.1

I have tried to find and follow various tutorial on how to add firebase to a Flutter web app. Non of them helped me, since the problem seems to come from the firebase_core package. I have tried to add the firebase_core_web package. I also downgraded various firebase packages and tried with diffrent combinations based on what recommendations I could find online. I always got the same error.
I have upgraded flutter to the newest version.
The error can be simply recreated by creating af new flutter project, and install firebase_core. If you then run the app on chrome, the error will show up in the terminal. At least, that is what happens to me ...
!!! SOLVED !!!
I solved the problem with simply repairing the pub-cache folder using the " flutter pub cache repair " command. Hallelujah !
