I made a flutter project, which is an android app, so I used the following things from firebase.

-Firestore  
-Database  
-Auth  
and I ran commands flutter pub add firebase\_…

this is my flutter pub get -

```gradle
Resolving dependencies... 
  js 0.6.7 (0.7.1 available)
  leak_tracker 10.0.0 (10.0.4 available)
  leak_tracker_flutter_testing 2.0.1 (3.0.3 available)
  leak_tracker_testing 2.0.1 (3.0.1 available)
  material_color_utilities 0.8.0 (0.11.1 available)
  meta 1.11.0 (1.12.0 available)
  test_api 0.6.1 (0.7.0 available)
  vm_service 13.0.0 (14.1.0 available)
Got dependencies!
8 packages have newer versions incompatible with dependency constraints.
Try `flutter pub outdated` for more information.

```

This error below I get when I run my main.dart file on My physical device.

```gradle

BUILD FAILED in 2m 33s

```

i’m attaching my app level build.gradle file-

```gradle
buildscript {
    ext.kotlin_version = '1.7.20'

    repositories {
        google()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:7.4'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

        // Add the classpath for Google Services plugin
        classpath 'com.google.gms:google-services:4.4.1'
    }
}

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
}

```

now project/root level build.gradle -

```gradle
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.lets_chat"
    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.example.lets_chat"
        // 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:32.7.4')
    implementation 'com.google.firebase:firebase-analytics'
}

```

now gradle-wrapper.properties -

```gradle
distributionBase=GRADLE_USER_HOME

distributionPath=wrapper/dists

zipStoreBase=GRADLE_USER_HOME

zipStorePath=wrapper/dists

distributionUrl=https\://services.gradle.org/distributions/gradle-7.4-all.zip

```

and now gradle.properties -

```gradle
org.gradle.jvmargs=-Xmx4G

android.useAndroidX=true

android.enableJetifier=true

```

Earlier it was showing me some error like expected kotlin/gradle version 1.7.1 but got 1.90, so online it told me to edit gradle version to 7.4 everywhere but still it is not working.

Don’t confuse Android Gradle Tools version with Gradle version.  
AGP unluckily called their artifact “gradle” as in “com.android.tools.build:gradle”, but there you configure the AGP version and for that no 7.4 exists, just 7.4.0 if that is what you wanted.

Don’t try to use an AGP version that does not exist
