I tried to geneate the apk in Flutter, and then it show me this error:
ERROR: R8: java.lang.IllegalArgumentException: Provided Metadata instance has version 2.1.0, while maximum supported version is 2.0.0. To support newer versions, update the kotlinx-metadata-jvm library.
FAILURE: Build failed with an exception.
- What went wrong:
Execution failed for task ‘:app:minifyReleaseWithR8’.
A failure occurred while executing com.android.build.gradle.internal.tasks.R8Task$R8Runnable
Compilation failed to complete
This is my android/build.gradle:
allprojects {
repositories {
google()
mavenCentral()
}
}
rootProject.buildDir = "../build"
subprojects {
project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
project.evaluationDependsOn(":app")
}
tasks.register("clean", Delete) {
delete rootProject.buildDir
}
And this is my app/build.gradle:
plugins {
id "com.android.application"
// START: FlutterFire Configuration
id 'com.google.gms.google-services'
// END: FlutterFire Configuration
id "kotlin-android"
// The Flutter Gradle Plugin must be applied after the Android and Kotlin Gradle plugins.
id "dev.flutter.flutter-gradle-plugin"
}
android {
namespace = "com.mynoona.noona"
compileSdk = flutter.compileSdkVersion
ndkVersion = "25.1.8937393"
compileOptions {
sourceCompatibility = JavaVersion.VERSION_17
targetCompatibility = JavaVersion.VERSION_17
}
kotlinOptions {
jvmTarget = JavaVersion.VERSION_17
}
defaultConfig {
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId = "com.mynoona.noona"
// You can update the following values to match your application needs.
// For more information, see: https://flutter.dev/to/review-gradle-config.
minSdk = 23
targetSdk = flutter.targetSdkVersion
versionCode = flutter.versionCode
versionName = flutter.versionName
multiDexEnabled true
}
buildTypes {
release {
// TODO: Add your own signing config for the release build.
// Signing with the debug keys for now, so `flutter run --release` works.
signingConfig = signingConfigs.debug
}
}
}
flutter {
source = "../.."
}
And this is my setting.gradle:
pluginManagement {
def flutterSdkPath = {
def properties = new Properties()
file("local.properties").withInputStream { properties.load(it) }
def flutterSdkPath = properties.getProperty("flutter.sdk")
assert flutterSdkPath != null, "flutter.sdk not set in local.properties"
return flutterSdkPath
}()
includeBuild("$flutterSdkPath/packages/flutter_tools/gradle")
repositories {
google()
mavenCentral()
gradlePluginPortal()
}
}
plugins {
id "dev.flutter.flutter-plugin-loader" version "1.0.0"
id "com.android.application" version "8.3.2" apply false
// START: FlutterFire Configuration
id "com.google.gms.google-services" version "4.3.15" apply false
// END: FlutterFire Configuration
id "org.jetbrains.kotlin.android" version "2.1.0" apply false
}
include ":app"
And this is my gradle.properties:
org.gradle.jvmargs=-Xmx4G -XX:MaxMetaspaceSize=2G -XX:+HeapDumpOnOutOfMemoryError
android.useAndroidX=true
android.enableJetifier=true

I don’t know if is this the best way, but for me solved changing version of the kotlin.android plugin to 2.0.0.
Instead of downgrading back to 2.0.0, you could do exactly what is suggested in the error message and add this dependency to
build.gradle
