I am very new to Dart, and coding in general. I have produced this code after watching tutorials on YouTube. For the most part, I have been able to troubleshoot most of my problems on my own, yet I cannot figure out my most recent errors. I have using firebase for authentication as soon as I write code in main.dart

Future <void> main() async {
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp().then((value) => Get.put(AuthController()));
runApp(const MyApp());
}

and if i run the app, I get the following error

E/flutter ( 5661): [ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: 
[core/not-initialized] Firebase has not been correctly initialized.
E/flutter ( 5661): 
E/flutter ( 5661): Usually this means you've attempted to use a Firebase service before 
calling `Firebase.initializeApp`.

My android/app/build.gradle has the following config:

defaultConfig {
    // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
    applicationId "getin.******.definer_lms" // edited for security purpose
    minSdkVersion 23
    targetSdkVersion 29
    versionCode flutterVersionCode.toInteger()
    versionName flutterVersionName
    multiDexEnabled true
}
.....
dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation platform('com.google.firebase:firebase-bom:29.1.0')
implementation 'com.android.support:multidex:1.0.3'
}

.....
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'

}

My android/build.gradle has the following config:

dependencies {
    classpath 'com.android.tools.build:gradle:4.1.0'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    classpath 'com.google.gms:google-services:4.3.10'
}

can someone please find what is wrong here?

You need to write this way :

  WidgetsFlutterBinding.ensureInitialized();
  
  await Firebase.initializeApp().then((value)  {
      
    Get.put(AuthController());
    
    runApp(const MyApp());
  });
