PlatformException error in dart_vm_initializer.cc

Question

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp();
  runApp(TestApp());
}

I got this error while running my app at the line await Firebase.initializeApp();

E/flutter ( 9119): [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)

Please note that I am using firebase core version as below

 firebase_core: ^1.20.0

Right now, I'm trying to run this on an android emulator. I have added google-services.json to <app_name>/android/app, the following to <app_name>/android/build.gradle

dependencies {
    ...
    classpath 'com.google.gms:google-services:4.3.13'
    ...
}

and this to <app_name>/android/app

dependencies {
    ...
    implementation platform('com.google.firebase:firebase-bom:30.3.1')
    implementation 'com.google.firebase:firebase-analytics'
    ...
}

Any would be appreciated. Thanks.

Answer 1

could you please show android/app/build.gradle ?
and try adding apply plugin: 'com.google.gms.google-services'
then it looks something like this:

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

to this:

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"
apply plugin: 'com.google.gms.google-services'
