Snackbar.addCallback in kotlin

val snackBar = Snackbar
                .make(view, "Text Snackbar", Snackbar.LENGTH_LONG)
                .addCallback(object : BaseTransientBottomBar.BaseCallback() {
                    override fun onShown(transientBottomBar: Snackbar?) {
                        super.onShown(transientBottomBar)
                    }

                    override fun onDismissed(transientBottomBar: Snackbar?, event: Int) {
                        super.onDismissed(transientBottomBar, event)
                    }
                })

        val snackBarView = snackBar.view
        snackBarView.setBackgroundColor(Color.RED)
        snackBar.show()
