Check this https://pub.dev/packages/flutter_local_notifications#gradle-setup

You need to add a compile option as well as a dependency for the the desugaring core library

[khalidrinaldy]

I added on build.gradle:app like

`compileOptions {
sourceCompatibility JavaVersion.VERSION_17
targetCompatibility JavaVersion.VERSION_17

    // add this code
    coreLibraryDesugaringEnabled true
}`

`dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation platform('com.google.firebase:firebase-bom:30.4.1')
implementation 'com.google.firebase:firebase-analytics'

// add these codes
// you can upgrade the window library too
implementation 'androidx.window:window:1.0.0'
implementation 'androidx.window:window-java:1.0.0'
coreLibraryDesugaring 'com.android.tools:desugar_jdk_libs:1.2.2'

}`

this solved my issue

i will try these solutions as i am still not able to compile correctly for google to accept my app
anyhow the documentation should be updated for clarity

Yeah, it's Buddy's @MaikuB who can fix this officially, or the Flutter official team can fix this natively.
