在 LazyVGrid 中将最后一行居中

问题描述

在 LazyVGrid 中，我显示来自服务器的数据（这里我以字母表为例），我的目标是在中心显示最后一行而不是 leading如果最后一行包含少于 3 个项目。可行吗？

目前，它看起来像这样：

struct ContentView: View {
   let alphabet = ["A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z"]
    let preference = [
            GridItem(.flexible()),GridItem(.flexible()),GridItem(.flexible())
        ]
    var body: some View {
    ScrollView {
        LazyVGrid(columns: preference) {
        ForEach(alphabet,id: \.self) { value in
            ZStack {
                Rectangle()
                    .frame(width: 120,height: 120)
                    .foregroundColor(Color(UIColor.systemIndigo))
                    .cornerRadius(16)
                Text(value.description)
                    .foregroundColor(.white)
                    .font(.title)
                    }
                }
            }
        }
    }
}
