                        .frame(width: 200, height: 200)
                        //.fill(colors.mid)
                        //.opacity(showingSheet ? 1.0 : 0.0)
                        .transition(.scale)
                }
                
            
        }
        
        
        
    }
}

struct ReviewsPageView_Previews: PreviewProvider {
    static var previews: some View {
        ReviewsPageView()
    }

这是我的动画过渡代码^^^

我想让框在单击按钮时展开，然后在再次单击时缩小。现在该框只是出现没有任何过渡，然后在第二次单击时过渡到较小的形状。

这是它的样子：
