val shapeAppearanceModel = ShapeAppearanceModel.builder().apply {
setAllCorners(RoundedCornerTreatment())
setAllCornerSizes(50f)
setAllEdges(TriangleEdgeTreatment(50f, false))
}.build()
val drawable = MaterialShapeDrawable(shapeAppearanceModel).apply {
setTint(ContextCompat.getColor(requireContext(), R.color.teal_200))
paintStyle = Paint.Style.FILL_AND_STROKE
