@500InternalErr - what JDK are you running to build you Flutter apps? It must be a later version. If you create a Flutter app with the latest Flutter SDK, it still has these compiler options:

    compileOptions {
        sourceCompatibility = JavaVersion.VERSION_1_8
        targetCompatibility = JavaVersion.VERSION_1_8
    }

We follow what Flutter app compiler compatibility options produce, and at this moment in time, it is still has these compiler options.

Hi sorry for late response
I'm using gradle 8.7.3 and get below error

Could not resolve all artifacts for configuration 'classpath'.
> Could not resolve com.android.tools.build:gradle:8.7.3.
  Required by:
      unspecified:unspecified:unspecified > com.android.application:com.android.application.gradle.plugin:8.7.3
   > Dependency requires at least JVM runtime version 11. This build uses a Java 8 JVM.

[russellwheatley]

Right, so if you use a later version of the android gradle plugin then it might require you to use a later JVM runtime. The default Flutter app has this plugin version:

 id "com.android.application" version "8.1.0" apply false
