I added latest version of firebase dependency and initialize firebase in my flutter app but same issue happened guide someone:
Check below of my Firebase code initilize in flutter project:
void main() async{
WidgetsFlutterBinding.ensureInitialized();
await Firebase.initializeApp();
runApp(const MyApp());
}
check below build gradel file of app level:
plugins {
id "com.android.application"
id "kotlin-android"
id "dev.flutter.flutter-gradle-plugin"
id "com.google.gms.google-services"
}
def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
localPropertiesFile.withReader('UTF-8') { reader ->
localProperties.load(reader)
}
}
def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
flutterVersionCode = '1'
}
def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
flutterVersionName = '1.0'
}
android {
namespace "com.example.flutter_firebase"
compileSdk flutter.compileSdkVersion
ndkVersion flutter.ndkVersion
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
kotlinOptions {
jvmTarget = '1.8'
}
sourceSets {
main.java.srcDirs += 'src/main/kotlin'
}
defaultConfig {
multiDexEnabled true
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId "com.example.flutter_firebase"
// You can update the following values to match your application needs.
// For more information, see: https://docs.flutter.dev/deployment/android#reviewing-the-gradle-build-configuration.
minSdkVersion flutter.minSdkVersion
targetSdkVersion flutter.targetSdkVersion
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
}
buildTypes {
release {
// TODO: Add your own signing config for the release build.
// Signing with the debug keys for now, so `flutter run --release` works.
signingConfig signingConfigs.debug
}
}
}
flutter {
source '../..'
}
dependencies {
implementation(platform("com.google.firebase:firebase-bom:32.8.1"))
implementation("com.google.firebase:firebase-analytics")
implementation 'com.android.support:multidex:1.0.3'
}
check below code of build gradel of project level:
buildscript {
ext.kotlin_version = '1.9.23'
repositories {
// Make sure that you have the following two repositories
google() // Google's Maven repository
mavenCentral() // Maven Central repository
}
dependencies {
// Add the Maven coordinates and latest version of the plugin
classpath ("com.google.gms:google-services:4.4.1")
classpath ("com.google.firebase:firebase-appdistribution-gradle:4.2.0")
classpath ("com.google.firebase:firebase-crashlytics-gradle:2.9.9")
classpath ("com.google.firebase:firebase-crashlytics-gradle:2.9.9")
classpath ("com.google.firebase:perf-plugin:1.4.2")
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.9.23"
}
}
allprojects {
repositories {
google()
mavenCentral()
}
}
rootProject.buildDir = '../build'
subprojects {
project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
project.evaluationDependsOn(':app')
}
tasks.register("clean", Delete) {
delete rootProject.buildDir
}

According to the document you need to add parameter while initializing the firebase like
First make sure you’ve downloaded, and imported the google-services.json file properly.
Secondly, make sure you’ve followed steps for connecting firebase project to your flutter project.
Official documentation: https://firebase.google.com/docs/flutter/setup?platform=android
Important:
In order to be able to run the "firebase" command, you have to install the Firebase CLI on your device.
Also included in the official documentation https://firebase.google.com/docs/cli#setup_update_cli
Workaround:
Firebase options can be "hardcoded" but it’s not the best soultion.
