I'm already using Kotlin latest version still Flutter wants me to upgrade

Question

When I run the emulator I get these errors and fix :

e: file:///C:/Users/xunre/.gradle/caches/modules-2/files-2.1/org.jetbrains.kotlin/kotlin-stdlib/2.1.10/d3028429e7151d7a7c1a0d63a4f60eac86a87b91/kotlin-stdlib-2.1.10.jar!/META-INF/kotlin-stdlib.kotlin_moduleModule was compiled with an incompatible version of Kotlin. The binary version of its metadata is 2.1.0, expected version is 1.8.0.

My android android\settings.gradle(already latest kotlin version "2.1.10"):

plugins {
    id "dev.flutter.flutter-plugin-loader" version "1.0.0"
    id "com.android.application" version "8.1.0" apply false
    id "org.jetbrains.kotlin.android" version "2.1.10" apply false
}

I have upgraded plugins with Gradle's declarative plugins {} block.

The app is running fine on the emulator and I got this error when I did the flutter build apk. This is a project 2 years ago I had to do a lot of fix for it to get running. so my question is when it runs on an emulator why did the build failed?

Answer 1

if jdk version is not compatible with gradle version then it shows error, check with jdk and gradle version.

Here check compatibility, Hope so this will resolve your issue.
