7 3 First of all I have to clarify I'm not asking what's an inline function is or what's an inline class is. There's nowhere in Kotlin Language documentation or specification any reference to an inline constructor but if you look in Arrays.kt source you see this class: ByteArray has an inline constructor: /** * An array of bytes. When targeting the JVM, instances of this class are represented as `byte[]`. * @constructor Creates a new array of the specified [size], with all elements initialized to zero. */ public class ByteArray(size: Int) { /** * Creates a new array of the specified [size], where each element is calculated by calling the specified * [init] function. * * The function [init] is called for each array element se...

Flutter allows to support of Kotlin language. How can I integrate my kotlin file with Flutter project. There is no option to add/create a Kotlin file (in New menu) in Android Studio. I think the kotlin files can only be used in the platform-specific plugins. E.g. you have platform-specific implementation for both iOS and android and you can use kotlin for the Android part. The Flutter SDK is used directly with Dart. Open your Android module in android so you can add your kotlin files

I get this error when try to run my Android application and I am not using Kotlin at all, application is written in Java... Class kotlin.reflect.jvm.internal.FunctionCaller$FieldSetter can not access a member of class com.android.build.gradle.tasks.ManifestProcessorTask with modifiers "private" I solved this way. 1. Delete all the .gradle folders 2. Invalidate caches / restart everything is OK for me.
