  • Hi Mohammed, Your exception stack will be easier for others to read if you put it in a `code` section. Is the error happening during the build, test, packaging, or deployment phase? Does the error explanation in the stack dump make any sense: `Unhandled Exception: Null check operator used on a null value`? Is the source of the exception in your code or in a third-party library? Hope these questions help get you closer to finding the cause. Good luck. – devdanke Dec 01 '21 at 12:48
  • Does this answer your question? [Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.5.1, expected version is 1.1.15](https://stackoverflow.com/questions/67699823/module-was-compiled-with-an-incompatible-version-of-kotlin-the-binary-version-o) – snakecharmerb Dec 04 '21 at 15:20

The solution to this problem is to ensure that when initializing firebase in your project, ensure you include the "name" parameter of your project. See the example below.

Future<void> main() async {


WidgetsFlutterBinding.ensureInitialized();

  await Firebase.initializeApp(
    name: 'firebase-project-name',
    options: DefaultFirebaseOptions.currentPlatform,
  );
}

  • This worked for me. Followed the doc here https://firebase.google.com/docs/flutter/setup?platform=ios and it was just showing a blank screen without the name... Thanks Stan ! – schankam Mar 24 '23 at 21:03
