SwiftUI 动画期间文本被缩短

Question

我尝试构建一个可扩展的菜单，文本应限制为 2 行，但是当文本很长并且菜单展开时，文本会在动画期间缩短...

struct MenuGroup : View {
    
    @State var show = false
    var text: String
    var body: some View {
        
        VStack {
            Button(action: {
                self.show.toggle()
            }) {
                HStack {
                    Text(text)
                        .lineLimit(2)
                    Spacer()
                }.padding(.all, 16)
            }
            
            if show  {
                ForEach(1...3, id: \.self) { item in
                    Text("Option \(item)")
                }
            }
        }
    }
}


struct ContentView: View {

    var body: some View {
        ScrollView {
            MenuGroup(text: "long text long text long text long text long text long text")
            MenuGroup(text: "long text long text long text long text long text long text")
            MenuGroup(text: "long text long text long text long text long text long text")
        } .animation(.linear(duration: 1.1))
    }
}

解决方案是在Text上应用.fixedSize(horizontal: false, vertical: true)
