Hi @tristanjclarke, this is likely due to the gradle version you're using. Can you try the comments in https://stackoverflow.com/questions/73453524/what-is-causing-this-error-com-android-tools-r8-internal-nc-sealed-classes-are to see if it helps?

Hi @danagbemava-nc I tried this without any luck. Please see my files below:

build.gradle:

buildscript {
    ext.kotlin_version = '1.9.20'
    repositories {
        google()
        mavenCentral()
        maven {
            url 'https://plugins.gradle.org/m2/'
        }
        maven {
            url 'http://developer.huawei.com/repo/'
            allowInsecureProtocol = true
        }
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:7.3.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.3.14'
        classpath 'com.google.firebase:firebase-crashlytics-gradle:2.8.0'
    }
}

def noUnity = getGradle().getStartParameter().getTaskRequests().toString().toLowerCase().contains("nounity")

allprojects {
    repositories {
        if (!noUnity) {
            flatDir {
                dirs "${project(':unityLibrary').projectDir}/libs"
            }
        }
        google()
        mavenCentral()
        maven {
            url 'http://developer.huawei.com/repo/'
            allowInsecureProtocol = true
        }
    }
}

rootProject.buildDir = '../build'

subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}

subprojects {
    project.evaluationDependsOn(':app')
}

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

setting.gradle:

def noUnity = getGradle().getStartParameter().getTaskRequests().toString().toLowerCase().contains("nounity")

if (noUnity) {
    include ':app'
} else {
    include ':app', ':unity-classes'
}

def flutterProjectRoot = rootProject.projectDir.parentFile.toPath()

def plugins = new Properties()
def pluginsFile = new File(flutterProjectRoot.toFile(), '.flutter-plugins')
if (pluginsFile.exists()) {
    pluginsFile.withReader('UTF-8') { reader -> plugins.load(reader) }
}

plugins.each { name, path ->
    def pluginDirectory = flutterProjectRoot.resolve(path).resolve('android').toFile()
    include ":$name"
    project(":$name").projectDir = pluginDirectory
}

if (!noUnity) {
    include ":unityLibrary"
    project(":unityLibrary").projectDir = file("./unityLibrary")
}

gradle.beforeProject({ project->
    if (project.hasProperty("target-platform") && !project.getProperty("target-platform").split(",").contains("android-arm")) {
        project.setProperty("target-platform", "android-arm,android-arm64")
    }
})

Hi @tristanjclarke, can you try https://docs.flutter.dev/release/breaking-changes/flutter-gradle-plugin-apply to see if that helps?

Also, are you only facing this issue on CI?

Without additional information, we are unfortunately not sure how to resolve this issue. We are therefore reluctantly going to close this bug for now.
If you find this problem please file a new issue with the same description, what happens, logs and the output of 'flutter doctor -v'. All system setups can be slightly different so it's always better to open new issues and reference the related ones.
Thanks for your contribution.
