I’ve been struggling with a problem in my Flutter web project for a while now. I’m trying to set up Firebase as the backend but I keep running into errors when initializing the app.
Here’s what I’ve done so far:
- Added Firebase config to index.html
- Set up main.dart to initialize Firebase
- Updated pubspec.yaml with Firebase dependencies
But when I run the app, I get this error:
FirebaseError: Firebase: No Firebase App '[DEFAULT]' has been created - call Firebase App.initializeApp() (app/no-app).
I’ve double-checked my setup and it looks correct to me. Has anyone run into this issue before? What am I missing?
I can share more code snippets if needed. Any help would be much appreciated!
I encountered a similar issue when integrating Firebase with my Flutter web app. One crucial step that’s often overlooked is ensuring that the Firebase SDK is properly loaded before initializing the app. Check your index.html file and make sure the Firebase scripts are included in the correct order. Additionally, verify that your Firebase configuration object in index.html matches the one in your Firebase console. If the problem persists, try wrapping your initialization code in a try-catch block to capture any specific errors that might be occurring during the process. This can provide more detailed information about what’s going wrong during initialization.
hey there! i’ve had similar issues before. have u tried calling Firebase.initializeApp() in your main() function before runApp()? sometimes the timing can be tricky. also, double-check ur config in index.html - maybe there’s a typo? what version of firebase are u using? curious to hear more about ur setup!
yo BoldPainter37, sounds frustrating! make sure ur using the latest firebase package versions. also, try moving the initialization code to a separate function and calling it before runApp(). if that dont work, check if ur firebase project settings match ur app. good luck!
