[kotlin] flatc --kotlin monster.fbs does not produce code compatible with the kotlin/ directory of this repository

[mikeholler]

The kotlin/ directory of this repository contains the FlatBuffers core library written in a multi-platform way. The top-level package it uses is com.google.flatbuffers.kotlin. When I compile flatc locally and run it against monster.fbs, I get, among other things, Monster.kt. The top of this file looks like this:

// automatically generated by the FlatBuffers compiler, do not modify

package MyGame.Sample

import java.nio.*
import kotlin.math.sign
import com.google.flatbuffers.*

@Suppress("unused")
class Monster : Table() {

    fun __init(_i: Int, _bb: ByteBuffer)  {
        __reset(_i, _bb)
    }

Notice the import, which is com.google.flatbuffers.*. This is different from com.google.flatbuffers.kotlin.*, and means this kotlin code is not compatible with the kotlin/ directory. I see that I can probably use this generated Kotlin code with the java/ library code. But what I'm specifically interested is getting generated code to work with kotlin multiplatform, and the kotlin/ directory. How do I generate code that uses the com.google.flatbuffers.kotlin imports?

Compiler Version: v2.0.6 Operating System: Ubuntu 20.04 FlatBuffers version: v2.0.6

I believe @paulovap is the most active java/kotlin maintainer

Hi @mikeholler. The kotlin code generated code still uses the java runtime, so you must declare the flatbuffers runtime for java as dependency. The code you see on /kotlin folder is still in development and is not production code.

I am working on a pure kotlin runtime and hope to remove this dependency from java soon.
