build fails after upgrade from 3.15.5

trying to build my app with adapty_flutter-3.17.0 using flutter 3.41.9 – see below.
those jvm settings seem to ask for a bump...

e: file:///Users/tom/.pub-cache/hosted/pub.dev/adapty_flutter-3.17.0/android/src/main/kotlin/com/adapty/flutter/AdaptyOnboardingNativeView.kt:23:62 Cannot inline bytecode built with JVM target 11 into bytecode that is being built with JVM target 1.8. Specify proper '-jvm-target' option.

Hi @tomquas, thank you for the report! We're taking a look.

In the meantime, as a temporary workaround, you can bump the plugin's JVM target to 11. Open the plugin's android/build.gradle in your pub cache (e.g. ~/.pub-cache/hosted/pub.dev/adapty_flutter-3.17.0/android/build.gradle) and update both blocks:

compileOptions {
    sourceCompatibility JavaVersion.VERSION_11
    targetCompatibility JavaVersion.VERSION_11
}
kotlinOptions {
    jvmTarget = '11'
}

We'll ship a proper fix in an upcoming release.
