How can I resolve FlutterFire CLI errors when generating firebase_options.dart?

I'm using Firebase in my Flutter project, and until last year I initialized it with a parameter-free call:
PYTHONawait Firebase.initializeApp();
Since the recent update, Firebase initialization requires options, so the compiler instructs me to generate a file named firebase_options.dart. I've followed the official documentation (https://firebase.google.com/docs/flutter/setup?hl=de&platform=android) step by step: I've installed the Firebase CLI, logged into my Google account, added firebase_core, and activated flutterfire_cli. However, I'm stuck when executing the following command:
BASHflutterfire configure
When I run this in the Firebase CLI console, it prompts:
FlutterAppRequiredException: The current directory does not appear to be a Flutter application project.
But when I run it in my Flutter project folder, I get the error:
BASHflutter Failed to fetch your Firebase projects. Fetch failed with this: FirebaseCommandException: An error occured on the Firebase CLI when attempting to run a command. COMMAND: firebase --version ERROR: The FlutterFire CLI currently requires the official Firebase CLI to also be installed, see https://firebase.google.com/docs/cli#install_the_firebase_cli for how to install it. ? Would you like to create a new Firebase project? (y/n) › yes
This appears to create a loop. What should I do next to resolve this issue and successfully generate the firebase_options.dart file?

It looks like the FlutterFire CLI isn’t finding the official Firebase CLI—even though you’ve installed it elsewhere—so the solution is to make sure that the Firebase CLI (firebase-tools) is correctly installed and available in your PATH when running commands from your Flutter project folder.
Below are some steps to help resolve the loop:
1. Verify the Firebase CLI Installation
Run the following command in your terminal within your Flutter project folder:
BASHfirebase --version
If this command fails or shows an unexpected result, it means the Firebase CLI isn’t installed or isn’t in your PATH.
2. Install (or Reinstall) the Firebase CLI
If you haven’t installed it, or if it isn’t recognized, install the official Firebase CLI with npm:
BASHnpm install -g firebase-tools
Make sure that your npm global packages directory is in your PATH. If you already installed it, you can try reinstalling or updating it:
BASHnpm update -g firebase-tools
3. Login With the Firebase CLI
Confirm that you are properly logged in by running:
BASHfirebase login
If you’re using this command in your project folder, it ensures that the CLI has the proper authentication context.
4. Run flutterfire Configure
Once the Firebase CLI correctly responds to the version command and you’re logged in, run the FlutterFire configuration from your Flutter project folder:
BASHflutterfire configure
This command will scan your Flutter project, prompt you for your supported platforms (Android, iOS, Web) and Firebase project, and then generate the firebase_options.dart file.
5. Additional Checks
- Node.js Version: Ensure you’re running a recent LTS version of Node.js that is compatible with firebase-tools.
- PATH Issues: Sometimes, if you installed firebase-tools with npm but your shell doesn’t pick up the new binaries, restart the terminal or explicitly add the npm global directory to your PATH.
- Project Location: Double-check that you’re running the command from the root of your Flutter project (where the
pubspec.yamlis located).
Following these steps should help you escape the loop and allow flutterfire configure to finish successfully. Once it finishes, your firebase_options.dart file will be generated so that you can initialize Firebase using:
DARTawait Firebase.initializeApp( options: DefaultFirebaseOptions.currentPlatform, );
Let me know if you have any further issues!
