I'm trying from compileSdk 33 to compileSdkVersion 33 and adding plugins id "com.android.application" top of app/build.gradle file

plugins {
    id "com.android.application"
    id "kotlin-android"

}

CompileSdkVersion is deprecated, please use the new compileSdk instead.

android {
   namespace "your.package.name"
   compileSdk flutter.compileSdkVersion (or any SDK like 33 or 34)
