[SOLVED] No Firebase App '[DEFAULT]': for 'Add to App' flutter app with firebase

No Firebase App '[DEFAULT]': for 'Add to App' flutter app with firebase_crashlytics

TLDR;

How can we configure firebase crashlytics with flutterfire for Add to App I've seen other stackoverflow questions and tried those options already

Longer version:

Parent app, doesn't have any firebase plugins nor firebase.initialize() calls. It just refers to the child package app
In the child app we have fire base plugins and initialize calls.
If you are curious about our setup, its on medium.
In child's main.dart file we have the following code

    void main() {
      runZonedGuarded(() async {
        // Initialize Flutter bindings; must come first!
        WidgetsFlutterBinding.ensureInitialized();
        await Firebase.initializeApp(
        );
        ...

Call stack looks like this

[VERBOSE-2:ui_dart_state.cc(198)] Unhandled Exception: [core/no-app] No Firebase App '[DEFAULT]' has been created - call Firebase.initializeApp()

All was well with firebase 1.5.0 but I had to upgrade for crashlytics

Change in packages

So far what I have tried

Generate the file firebase_options.dart file from flutterconfigure and refer to it from the child with following syntax

 await Firebase.initializeApp(
      options: DefaultFirebaseOptions.currentPlatform,
    );

Also tried to give name parameter but that didn't help either.

Question is where is the [DEFAULT] project being referenced and how can I remove/edit it?

Solution

This issue should be fixed with the latest version of firebase_core and any additional flutterfire packages you might be using in your project.
