Im having an issue building the APK.

Flutter version: 3.29.3 Kotlin version: 1.8.22 AGP version: 8.7.0 FlutterRadioPlayer version: 3.0.2

FAILURE: Build failed with an exception.

• What went wrong: Execution failed for task ':flutter_radio_player:compileReleaseKotlin'.

  Could not resolve all files for configuration ':flutter_radio_player:kotlinCompilerPluginClasspathRelease'. Could not find org.jetbrains.kotlin:kotlin-serialization-compiler-plugin-embeddable:1.8.22. Searched in the following locations:

Hmm, Im not entire sure what the problem is but it seems like

1. You need to update your project kotlin version
2. You might need to update your build.gradle

[M1sterchamp]

im not sure how updating my kotlin version would help, since im already using the version that the FlutterRadioPlayer is explicitly asking for. As for the build.gradle update, my build.gradle files are all accurate to the best of my knowledge, but i shall share them below too.

android/app/build.gradle.kts

`plugins { id("com.android.application") id("kotlin-android") id("dev.flutter.flutter-gradle-plugin") }

android {

namespace = "com.example.peanfm_mobile"
compileSdk = flutter.compileSdkVersion
ndkVersion = "27.0.12077973" 

defaultConfig {
    applicationId = "com.example.peanfm_mobile" 
    minSdk = 31 
    targetSdk = flutter.targetSdkVersion
    versionCode = flutter.versionCode 
    versionName = flutter.versionName
}

compileOptions {
    sourceCompatibility = JavaVersion.VERSION_11
    targetCompatibility = JavaVersion.VERSION_11
}

kotlinOptions {
    jvmTarget = JavaVersion.VERSION_11.toString()
}

signingConfigs {
    create("release") {
        storeFile = file(System.getenv("UPLOAD_KEYSTORE_PATH") ?: "../upload-keystore.jks")
        storePassword = System.getenv("UPLOAD_STORE_PASSWORD") ?: "testbuild"
        keyAlias = System.getenv("UPLOAD_KEY_ALIAS") ?: "upload" 
        keyPassword = System.getenv("UPLOAD_KEY_PASSWORD") ?: "testbuild"
    }
}

buildTypes {
    release {
        signingConfig = signingConfigs.getByName("release") 
        isMinifyEnabled = true
        proguardFiles(
            getDefaultProguardFile("proguard-android-optimize.txt"),
            "proguard-rules.pro" 
        )
    }
}

}

flutter { source = "../.." } `

android/build.gradle.kts

`plugins { id("com.android.application") id("kotlin-android") id("dev.flutter.flutter-gradle-plugin") }

android {

namespace = "com.example.peanfm_mobile"
compileSdk = flutter.compileSdkVersion
ndkVersion = "27.0.12077973" 

defaultConfig {
    applicationId = "com.example.peanfm_mobile" 
    minSdk = 31 
    targetSdk = flutter.targetSdkVersion
    versionCode = flutter.versionCode 
    versionName = flutter.versionName
}

compileOptions {
    sourceCompatibility = JavaVersion.VERSION_11
    targetCompatibility = JavaVersion.VERSION_11
}

kotlinOptions {
    jvmTarget = JavaVersion.VERSION_11.toString()
}

signingConfigs {
    create("release") {
        storeFile = file(System.getenv("UPLOAD_KEYSTORE_PATH") ?: "../upload-keystore.jks")
        storePassword = System.getenv("UPLOAD_STORE_PASSWORD") ?: "testbuild"
        keyAlias = System.getenv("UPLOAD_KEY_ALIAS") ?: "upload" 
        keyPassword = System.getenv("UPLOAD_KEY_PASSWORD") ?: "testbuild"
    }
}

buildTypes {
    release {
        signingConfig = signingConfigs.getByName("release") 
        isMinifyEnabled = true
        proguardFiles(
            getDefaultProguardFile("proguard-android-optimize.txt"),
            "proguard-rules.pro" 
        )
    }
}

}

flutter { source = "../.." } `

as you can see i also tried explicitly adding https://storage.googleapis.com/download.flutter.io but i still get exactly the same error.
