点击特定视图时如何在 SwiftUI NavigationLink 中删除动画

Question

There is a favorite button in my view which has NavigationLink. Each time I press the favorite button, opacity animations also shows. I don't want to show any animation while I tapping the favorite buttons. I know how to remove animation at whole view, but I hope the animation works when I press outside of favorite buttons.

HStack {
    Image(systemName: "a.book.closed.fill")
        
    Text(book.name)
        
    Spacer()
        
    FavoriteButton(isFavorite: $isFavorite)
        .onChange(of: isFavorite) { newValue in
            book.isFavorite = newValue
            model.saveData()
        }
}

This is my book row view

ScrollView {
    ForEach(model.savedBookEntities) { elem in
        NavigationLink() {
            VocaView(book: elem)
        } label: {
            BookRow(book: elem)
        }
        .contextMenu() {
            // Some context menus
        }
    }
}

and this is my ScrollView in NavigationView

Animation happens on animatable parameter changing. If FavoriteButton does not change anything else inside, then try to disable animation for isFavorite , like

HStack {
    Image(systemName: "a.book.closed.fill")
        
    Text(book.name)
        
    Spacer()
        
    FavoriteButton(isFavorite: $isFavorite)
        .onChange(of: isFavorite) { newValue in
            book.isFavorite = newValue
            model.saveData()
        }
        .animation(nil, value: isFavorite)   // << here !!
}
//.animation(nil, value: isFavorite)   // << or here !!

also book.isFavorite might affect, so if above would not work for you try the same with book.isFavorite .
