var body: some View {
Spacer()
Text("Hello, world!")
.padding()
.background(Color.red)
Text("Hello, world!")
.padding(paddingLength)
.background(Color.yellow)
Spacer()
Button("update padding to 0") {
paddingLength = 0
}
.padding(.bottom)
Button("update padding to default") {
paddingLength = 16 // Do we have something like: Padding.defaultValue to use it?
}
.padding(.bottom)
Spacer()
}
}

I am not aware of any way to get the default value but you could solve it by letting the length property be an optional and set it to nil for the default value. Only downside of this is you can't call padding with the length attribute only so either call it with edges set to .all or use another property for this.
Here is a solution with a property for edges as well
#State var paddingLength: CGFloat? = nil
#State var edge: Edge.Set = .all
var body: some View {
Spacer()
Text("Hello, world!")
.padding()
.background(Color.red)
Text("Hello, world!")
.padding(edge, paddingLength)
.background(Color.yellow)
Spacer()
Button("update padding to 0") {
paddingLength = 0
}
.padding(.bottom)
Button("update padding to default") {
paddingLength = nil
}
.padding(.bottom)
Spacer()
}
