[Question]: Getting this error with The binary version of its metadata is 1.9.0, expected version is 1.7.1.

[simhead]

What is your question?

I have added android_alarm_manager_plus: ^4.0.3 to pubspec.yaml and when I run flutter build apk, I am getting this error: ''' /.pub-cache/hosted/pub.dev/android_alarm_manager_plus-4.0.3/android/src/main/kotlin/dev/fluttercommunity/plus/androidalarmmanager/AlarmBroadcastReceiver.kt: (27, 18): Class 'kotlin.Unit' was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.9.0, expected version is 1.7.1. The class is loaded from /Users/peterkim/.gradle/caches/transforms-4/44f32ef92a48a9a2ea0a5cd6f6ead497/transformed/jetified-kotlin-stdlib-1.9.23.jar!/kotlin/Unit.class '''

here is my build.gradle: ''' buildscript { ext.kotlin_version = '1.9.24' repositories { google() jcenter() }

dependencies {
    classpath 'com.android.tools.build:gradle:7.2.0'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}

} '''

can someone suggest how to fix this?

Please check plugin's requirements first and update your project accordingly: https://github.com/fluttercommunity/plus_plugins/tree/main/packages/android_alarm_manager_plus#requirements

You need to update Android Gradle Plugin version in your project.

can you tell me what's missing?

[vbuberen]

//     classpath 'com.android.tools.build:gradle:7.2.0'

Which version of the Android Gradle Plugin you use instead of this commented line? It needs to be at least 8.3.0.

I have tried as suggested and still getting the same error:

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
}

buildscript {
    ext.kotlin_version = '1.9.24'
    repositories {
        google()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:8.3.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:1.9.24"
    }
}

[bethel-m]

hello am getting the same error, any solutions yet

[bethel-m]

hello again, i tried this and it worked for me: i specified the kotlin version in the settings.gradle file, and i did not bother adding it again in the build.gradle file from this: plugins { id "dev.flutter.flutter-plugin-loader" version "1.0.0" id "com.android.application" version "7.3.0" apply false id "org.jetbrains.kotlin.android" version "1.7.10" apply false } to this: plugins { id "dev.flutter.flutter-plugin-loader" version "1.0.0" id "com.android.application" version "7.3.0" apply false id "org.jetbrains.kotlin.android" version "1.9.10" apply false }
