1. Create main button view and a number of submenu buttons — both should be cast to AnyView type.

2. Pass both to FloatingButton constructor:

   FloatingButton(mainButtonView: mainButton, buttons: buttons)

3. You may also pass a binding which will determine if the menu is currently open. You may use this to close the menu on any submenu button tap for example.

FloatingButton(mainButtonView: mainButton, buttons: buttons, isOpen: $isOpen)

4. Chain .straight() or .circle() to specify desired menu type.
5. Chain whatever you like afterwards. For example:

   FloatingButton(mainButtonView: mainButton, buttons: textButtons)
       .straight()
       .direction(.top)
       .alignment(.left)
       .spacing(10)
       .initialOffset(x: -1000)
       .animation(.spring())
   
   FloatingButton(mainButtonView: mainButton2, buttons: buttonsImage.dropLast())
       .circle()
       .startAngle(3/2 * .pi)
       .endAngle(2 * .pi)
       .radius(70)
       .layoutDirection(.counterClockwise)

spacing - space between submenu buttons
initialScaling - size multiplyer for submenu buttons when the menu is closed
initialOffset - offset for submenu buttons when the menu is closed
initialOpacity - opacity for submenu buttons when the menu is closed
animation - custom SwiftUI animation like Animation.easeInOut() or Animation.spring()
delays - delay for each submenu button's animation start - you can pass array of delays - one for each element - or you can pass delayDelta - then this same delay will be used for each element mainZStackAlignment - main button and submenu buttons are contained in one ZStack (not an overlay so the menu has a correct size), you can change this ZStack's alignment with this parameter inverseZIndex - inverse zIndex of mainButton and the children. Use, for example, if you have a negative spacing and want to change the order wholeMenuSize - pass CGSize binding to get updates of menu's size. Menu's size includes main button frame and all of elements' frames menuButtonsSize - pass CGSize binding to get updates of combined menu elements' size

direction - position of submenu buttons relative to main menu button
alignment - alignment of submenu buttons relative to main menu button

startAngle
endAngle
radius - distance between center of main button and centers of submenu buttons
layoutDirection - changes the button layout direction from the startAngle to the endAngle
