firebase, flutter error 'Could not resolve all files for configuration' - firebase

Question

today I was learning firebase and I got stuck while running the app.
following is the error that I got when I build the app after changes -:
Launching lib\main.dart on sdk gphone x86 arm in debug mode...
Running Gradle task 'assembleDebug'...
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':firebase_core:javaPreCompileDebug'.
> Could not resolve all files for configuration ':firebase_core:debugCompileClasspath'.
> Could not find auto-value-annotations.jar (com.google.auto.value:auto-value-annotations:1.6.5).
Searched in the following locations:
https://jcenter.bintray.com/com/google/auto/value/auto-value-annotations/1.6.5/auto-value-annotations-1.6.5.jar
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.
* Get more help at https://help.gradle.org
BUILD FAILED in 2s
Exception: Gradle task assembleDebug failed with exit code 1
below are the file where I made changes and I assume that I did correctly as I am new to firebase and flutter -: App\build.gradle
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'
}

try to add this
defaultConfig {
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId "com.example.game_app"
minSdkVersion 21
targetSdkVersion 30
multiDexEnabled true - !!!add this line
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
}
and also add multiDexEnabled imlimentation
dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation platform('com.google.firebase:firebase-bom:27.1.0')
implementation 'com.google.firebase:firebase-analytics-ktx'
implementation 'com.android.support:multidex:1.0.3' // add this line
}
