duration: change the duration of the animation
animationSpeed: change how fast the animation moves and what index the animation lands on
spinDirection: change the direction of animation
containerCount: number of containers that should appear on screen
containerSize: for vertical scroll, this is the width of each container produced by the builder function. For horizontal, this is the height
builder: a function that takes in an integer and returns a widget with height/width of containerSize
