Hi I’m new to flutter and firebase and I’M trying to connect my project to firebase. I’m following the buildscript syntax and trying to add firebase plugins to my project using it, I followed

https://firebase.google.com/docs/android/troubleshooting-faq?hl=en&authuser=0&_gl=1*1mugxk1*_ga*MTM1MTI4NTQxNy4xNzAwMjk4NjQ1*_ga_CW55HF8NVT*MTcxNjAyOTExOC4xNy4xLjE3MTYwMjkxMzguNDAuMC4w#add-plugins-using-buildscript-syntax

firebase’s website but when i put all the plugins and id’s it does not recognize them. let me show you my gradle files:

app level:

plugins {
    id "com.android.application"
    id "kotlin-android"
    id "dev.flutter.flutter-gradle-plugin"
    id 'com.google.gms.google-services'
    id 'com.google.firebase.appdistribution'
    id 'com.google.firebase.crashlytics'
    id 'com.google.firebase.firebase-perf'
}

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.connectio.connectio"
    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 {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.connectio.connectio"
        // 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 21
        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:33.0.0')
    implementation 'com.google.firebase:firebase-analytics'
}

android level:

buildscript {

    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::5.0.0'
        classpath 'com.google.firebase:firebase-crashlytics-gradle:3.0.1'
        classpath 'com.google.firebase:perf-plugin:1.4.2'
    }
}
/*

plugins {
    // ...

    // Add the dependency for the Google services Gradle plugin
    id 'com.google.gms.google-services' version '4.4.1' apply false
    //id 'com.android.application' version '7.2.2' apply false
    //id 'com.android.library' version '7.2.2' apply false
    //id 'org.jetbrains.kotlin.android' version '1.9.24' apply false

}

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
}

and I get this error:
