android {
compileSdkVersion 32
// compileSdkVersion flutter.compileSdkVersion
ndkVersion flutter.ndkVersion

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

kotlinOptions {
    jvmTarget = '1.8'
}

sourceSets {
    main.java.srcDirs += 'src/main/kotlin'
}

defaultConfig {
