                            size.width * 0.25f, size.height * 0.5f,  // First control point for gentle slope
                            size.width * 0.75f, size.height * 0.5f,  // Second control point for gentle slope
                            size.width * 0.9f, size.height,// End point
                        )
                        lineTo(size.width * 0.9f, size.height) // Ensure we are at the bottom-right corner
                        lineTo(size.width * 0.1f, size.height) // Line back to the bottom-left corner
                        close()
                    }
                    onDrawBehind {
                        drawPath(path, color = Color.Green, style = Fill)
                    }
                }
                .size(300.dp,200.dp)
        )
    }
