Spinner

This flutter package implements a simple Spinner animation that cycles through any number of fixed size child widgets. Useful for selecting a random word from a list and displaying it to a user.

It can animate vertically, up or down:

Or horizontally, left or right:

API

Spinner has several useful parameters. You can see them used in the example file

• 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

• curve: the curve for the animation to follow. Defaults to easeInOutCubic

• callback: a function called when the animation completes

• zoomFactor: optional zoom in by this amount during the animation. It looks something like this, with a zoom factor of 1.5:
