Flutter - File google-services.json is missing. The Google Services Plugin cannot function without it - flutter

Question

I am trying to run the flutter application on the android studio before now all works perfectly but after I changed my targetSdkVersion to targetSdkVersion 31 I started getting this error that says
Execution failed for task ':app:checkDebugAarMetadata'.
> Could not resolve all files for configuration ':app:debugRuntimeClasspath'.
> Could not resolve com.google.firebase:firebase-core:25.12.0.
Required by:
project :app
> No cached version of com.google.firebase:firebase-core:25.12.0 available for offline mode.
And google-services.json is available in my project. My pubspec.yaml for firebase_message is firebase_messaging: ^7.0.3, android/build.gradledependencies is
buildscript {
ext.kotlin_version = '1.3.61'
repositories {
google()
jcenter()
mavenCentral() // Maven Central repository
}
dependencies {
classpath 'com.android.tools.build:gradle:4.1.0'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath 'com.google.gms:google-services:4.2.0'
}
``` and my ```app/build.gradle``` dependencies is
dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
testImplementation 'junit:junit:4.12'
implementation 'com.google.firebase:firebase-analytics'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
implementation 'com.android.support:multidex:1.0.3'
implementation 'com.google.firebase:firebase-core:11.0.4'
implementation platform('com.google.firebase:firebase-bom:31.0.2')
}
Thanks, in advance, please let me know if there is any information is needed
I tried to clean the project, pub upgrade, pub get, flutter upgrade, and even tried downloading a new version of firebase_messaging and pasting it inside the project still the same error.

Answer 1

So I was able to solve this by first updating my firebase_messaging version in pubspec.yaml to firebase_messaging: ^13.0.4 And android/build.gradle dependencies is
buildscript {
ext.kotlin_version = '1.5.31'
repositories {
google()
jcenter()
mavenCentral() // Maven Central repository
}
dependencies {
classpath 'com.android.tools.build:gradle:4.1.3'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
classpath 'com.google.gms:google-services:4.3.13'
}
subprojects {
project.configurations.all {
resolutionStrategy.eachDependency { details ->
if (details.requested.group == 'com.android.support'
&& !details.requested.name.contains('multidex') ) {
details.useVersion "27.1.1"
}
if (details.requested.group == 'androidx.core'
&& !details.requested.name.contains('androidx') ) {
//details.useVersion "1.0.1"
details.useVersion "1.5.0"
}
}
}
}
}
allprojects {
repositories {
google()
jcenter()
mavenCentral() // Maven Central repository
}
}
rootProject.buildDir = '../build'
subprojects {
project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
project.evaluationDependsOn(':app')
}
task clean(type: Delete) {
delete rootProject.buildDir
}
And and my app/build.gradle dependencies is
def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
localPropertiesFile.withReader('UTF-8') { reader ->
localProperties.load(reader)
}
}
def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}
def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
flutterVersionCode = '1'
}
def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
flutterVersionName = '1.0'
}
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'com.google.gms.google-services'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"
android {
compileSdkVersion 33
sourceSets {
main.java.srcDirs += 'src/main/kotlin'
}
lintOptions {
disable 'InvalidPackage'
}
defaultConfig {
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId "appname"
minSdkVersion 20
//noinspection OldTargetApi
multiDexEnabled true
targetSdkVersion 33
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
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 "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
testImplementation 'junit:junit:4.12'
implementation 'com.google.firebase:firebase-analytics'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
implementation 'com.android.support:multidex:1.0.3'
implementation platform('com.google.firebase:firebase-bom:31.0.2')
}
The above solved the issue for me.
