Flutter use native Android & iOS YouTubePlayer to play videos

Question

There are many packages out there on pub.dev which utilize the YouTube iFrame API to play YT-videos inline. But I cannot find a package which utilizes the native player, so I decided to create my own. But I'm struggling to get it working on Android. By implementing io.flutter.plugin.platform.PlatformView on Android and adding com.google.android.youtube.player.YouTubePlayerView to the View:

internal class YTNativeView(context: Context, id: Int, creationParams: Map<String?, Any?>?) : PlatformView, YouTubePlayer.OnInitializedListener {
    private val ytPlayer = YouTubePlayerView(context)
    private val apiKey = "<your-api-key>"

    init {
        ytPlayer.initialize(apiKey, this)
    }

    override fun getView(): View = ytPlayer

    override fun dispose() {}

    override fun onInitializationSuccess(provider: YouTubePlayer.Provider, youTubePlayer: YouTubePlayer, b: Boolean) {
        youTubePlayer.loadVideo("QH2-TGUlwu4")
        youTubePlayer.play()
    }

    override fun onInitializationFailure(provider: YouTubePlayer.Provider, youTubeInitializationResult: YouTubeInitializationResult) {}
}

the following error is thrown:

Unhandled Exception: PlatformException(error, java.lang.IllegalStateException: A YouTubePlayerView can only be created with an Activity  which extends YouTubeBaseActivity as its context.

Then I tried to use com.google.android.youtube.player.YouTubePlayerFragment but I couldn't figure out how to properly build the view due to the lack of getFragmentManager(). Any ideas, solutions or hints?
