Android gradle build is failing after Flutter upgrade

Question

After upgrading to Flutter 3.24.3 I was asked to migrate to Gradle's declarative plugins {} block.

After following the migration process to gradle module: https://docs.flutter.dev/release/breaking-changes/flutter-gradle-plugin-apply

I started having the following error:

Gradle build error: Cannot find module entity for 'Module: 'android.audioplayers_android.unitTest''

build.gradle (app level):

plugins {
    id "com.android.application"
    id "kotlin-android"
    id "dev.flutter.flutter-gradle-plugin"
    id "com.google.gms.google-services"
    id "com.google.firebase.crashlytics"
}

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterVersionCode = "31"

def flutterVersionName = "3.1.1"


android {
    compileSdk 34

settings.gradle:

        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()

include ":app"

build.gradle (android level):

}

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

tasks.register("clean", Delete) {
    delete rootProject.buildDir

I have fixed the issue by adding apply false to settings.gradle plugin loader: Here is the corresponding line:

    id "dev.flutter.flutter-plugin-loader" version "1.0.0" apply false
