如何从geometryReader中删除动画？

import SwiftUI

struct ContentView: View {
    @State private var isAnimating = false
    
    var body: some View {
        GeometryReader { geometry in
            Rectangle()
                .fill(Color.blue)
                .frame(width: geometry.size.width * 0.8, height: geometry.size.height * 0.5)
                .scaleEffect(self.isAnimating ? 1.5 : 1.0)
                .animation(.easeInOut) // 要删除的动画修饰符
        }
        .onTapGesture {
            self.isAnimating.toggle()
        }
    }
}
