Locate position of view in SwiftUI

I am building a card game (Set) and when dealing the cards I am currently using

Code Block 
withAnimation{} and .transition(.move(edge: .bottom)

to have the cards animate from the bottom edge of the screen when the user taps the deal button. I want to make it so that the cards 'fly out' of the button and was wondering how I find the location of the button.

Once I find the position of the button I intend to use .offset to have them 'fly' out. Is there a better way?

I know it is possible using geometry reader, but I have not found out how to do so.

Here is my current code

Code Block 
		struct SetGameView: View {
			
			@ObservedObject var viewModel: SetViewModel = SetViewModel()
			var location: (CGFloat, CGFloat) = (0.0, 0.0)	 
 	
			var body: some View {
				VStack {
					HStack {
						Label("Score: \(viewModel.score)", systemImage: "face.dashed").font(.title).padding(.leading)
						Spacer()
					}
					Grid(viewModel.dealtCards) { card in
						CardView(card: card)
							.transition(.asymmetric(insertion: .move(edge: .bottom), removal: .move(edge: .leading)))
							.padding()
							.onTapGesture { withAnimation { viewModel.choose(card) } }
					} .onAppear { withAnimation(.easeInOut) { deal(12) } }
					Divider()
					HStack {
						CreateNewGameButton(viewModel: viewModel)
						DealNewCardbutton(viewModel: viewModel, deal: deal)
					}.padding(.horizontal).frame(maxHeight: 50)
				}
			}
			
			struct DealNewCardbutton: View {
				
				var viewModel: SetViewModel
				let deal: (Int) -> Void
				
				init(viewModel: SetViewModel, deal: @escaping (Int) -> Void) {
					self.viewModel = viewModel
					self.deal = deal
				}
				
				var body: some View {
					GeometryReader { geo in
						Button(action: {
							deal(3)
						}){
							ZStack {
								RoundedRectangle(cornerRadius: 10.0).foregroundColor(.blue)
								Text("Deal Three Cards").foregroundColor(.white)
							}
						}.onAppear {
							print(geo.frame(in: .global).midX, geo.frame(in: .global).midY)
						}
					}
				}
			}

Heres a video of how it currently works.



I want the cards to all 'fly out' from the deal button.
