SwiftUI 交易：根据外部状态制作一个动画或静止的按钮

我正在try 创建一个基于另一个视图的状态有条件地设置动画(永远重复)的视图.

下面的按钮可以在一个视图中完成所有操作...但这个州都是internal.我希望是external.

struct ButtonBouncerView: View {
    @State var active: Bool = false

    var body: some View {
        Circle()
            .scaleEffect(active ? 1.08: 1)
            .animation(Animation.default.repeatForever(autoreverses: true), value: active)
            .frame(width: 100, height: 100)
            .onTapGesture {
                useTransaction()
            }
            .onAppear {
                active = true
            }
    }

    func useTransaction() {
        var transaction = Transaction()
        transaction.disablesAnimations = active ? true : false

        withTransaction(transaction) {
            withAnimation {
                active.toggle()
            }
        }
    }
}

我试着这样做，使用事务API.然而，当我敲击时，这只会产生奇怪的动画效果，基本上是某种奇怪的摇摆，比如运动.

struct OutsideControllableButtonView: View {
    @State private var active: Bool = false

    var body: some View {
        VStack {
            OutsideControllableButtonScaler(active: $active)
            Button(action: { // CONTROLLER BUTTON!
                active.toggle()
            }) {
                Text("Control Button")
            }
            .padding()
            .background(Color.green)
            .foregroundColor(.white)
        }
    }
}

struct OutsideControllableButtonScaler: View {
    // When Active, the button
    @Binding var active: Bool

    var body: some View {
        Circle()
            .scaleEffect(active ? 1.08: 1)
            .animation(Animation.default.repeatForever(autoreverses: true), value: active)
            .frame(width: 100, height: 100)
            .onChange(of: active) { newValue in
                var transaction = Transaction(animation: newValue ? Animation.default.repeatForever(autoreverses: true) : nil)
                transaction.disablesAnimations = true
                withTransaction(transaction) {
                    self.active = newValue
                }
            }
    }
}

你有什么办法解决这个问题吗？
