Flutter firebase 未初始化

Question

am getting this error. Unhandled Exception: PlatformException(null-error, Host platform returned null value for non-null return value., null, null)

I have updated all firebase packages in.yaml, i still have this error

E/flutter (11230): [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: PlatformException(null-error, Host platform returned null value for non-null return value., null, null)

Let me also add i have made the call to initialize firebase. Once i remove the initialisation the app works fine but without firebase

Answer 1

add these two lines to your main.dart main function

void main() async{

 WidgetsFlutterBinding.ensureInitialized();
  // initializing the firebase app
  await Firebase.initializeApp();

   
runApp(MyApp());

}

Answer 2

This is probably caused by the new changes with Firebase CLI with firebase options. So to solve this do add:

in your terminal

$ flutterfire configure

then in your main

// Import the generated file
import 'firebase_options.dart';

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

You probably going to be asked to authenticate your firebase account so you' ll run this in your terminal

dart pub global activate flutterfire_cli
