FAILURE: Build failed with an exception. * Where: Build file 'D:\Kerja\******\*******\android\build.gradle' line: 9 -- Flutter

Question

I am updating to the latest flutter update since my terminal telling me there is a new flutter update. this is when my error show up when I try to run the app into my emulator

You are applying Flutter's app_plugin_loader Gradle plugin imperatively using the apply script method, which is deprecated and will be removed in a future release. Migrate to applying Gradle plugins with the declarative plugins block: https://flutter.dev/go/flutter-gradle-plugin-apply

Error: Gradle task assembleDebug failed with exit code 1

for further information, here's my current build.gradle file

allprojects {
    ext.kotlin_version = '1.9.22'
    repositories {
        google()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:7.3.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

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
}
