Could not determine the dependencies of task ':photo_manager:compileDebugKotlin'.

Unknown Kotlin JVM target: 21
i have recently upgrade android stuido to vAndroid Studio Ladybug | 2024.2.1 Patch 1and upgrade the gradle to this is the settings.gradle file
plugins {
id "dev.flutter.flutter-plugin-loader" version "1.0.0"
id "com.android.application" version "8.1.4" apply false
id "org.jetbrains.kotlin.android" version "1.9.10" apply false
}
and for build.gradle file is
android {
namespace = "com.example.untitled2"
compileSdk = flutter.compileSdkVersion
ndkVersion = flutter.ndkVersion

compileOptions {
    sourceCompatibility = JavaVersion.VERSION_1_8
    targetCompatibility = JavaVersion.VERSION_1_8
}

kotlinOptions {
    jvmTarget = JavaVersion.VERSION_1_8
}

defaultConfig {
    // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
    applicationId = "com.example.untitled2"
    // 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
}

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
    }
}

}
