Lifecycle callbacks are not called

[user576g]

I wonna AR view for Flutter
When I add module to the app, there is no exception, but just black view on the screen.

Put your attention that:

1. calbacks like ARSceneView#onArSessionCreated or SceneView#onCreate are not called;
2. it's flutter plugin, so FlutterFragmentActivity is used instead of AppCompatActivity.
   FlutterFragmentActivity extends FragmentActivity.

I'll be glad to read any suggestions.

Code:

package com.epam.arquest.ar_quest_plugin

import android.content.Context
import android.graphics.Color
import android.view.View
import android.widget.TextView
import io.flutter.plugin.platform.PlatformView
import io.github.sceneview.ar.ArSceneView
import io.github.sceneview.ar.arcore.ArSession
import io.github.sceneview.math.Position
import io.github.sceneview.math.Rotation
import io.github.sceneview.math.Scale
import io.github.sceneview.node.ModelNode

internal class ARView(
private val context: Context,
id: Int,
creationParams: Map<String?, Any?>?
) : PlatformView {

private val textView: TextView

init {
    textView = TextView(context)
    textView.textSize = 72f
    textView.setBackgroundColor(Color.rgb(255, 255, 255))
    textView.text = "Error! context is NOT ContextWrapper!"
}

override fun getView(): View {
    val arSceneView = ArSceneView(context)
    arSceneView.addChild(
            ModelNode(
                    position = Position(x = 0.0f, y = 0.0f, z = -4.0f),
                    rotation = Rotation(y = 90.0f),
                    scale = Scale(0.5f)
            )
    )
    print("asdf")
    arSceneView.onArSessionCreated = { arSession: ArSession ->
        // this is not called
        print("asdf")
        println(arSession)
    }
    arSceneView.onArSessionFailed = { exception: Exception ->
        // this is not called
        print("asdf")
        println(exception.stackTrace)
    }


    return arSceneView
}

override fun dispose() {}

}

Upd: If someone has the same issue. I solved it in this way: I replaced dependency 'io.github.sceneview:arsceneview:0.9.0' with "com.gorisse.thomas.sceneform:sceneform:1.21.0". I handled activity lifecycle callbacks by myself and called arSceneView.resume() in onResume() method.
So, it seems like io.github.sceneview:arsceneview can be used in application module only.

I faced the same issue with AR view for Flutter. First of all I created my own lifecycle owner and then called it when needed. Everything worked, but it was not comfortable. But now that the guys have updated the library 'io.github.sceneview:arsceneview:2.0.2' - everything works without any custom lifecycle classes.
