Often a user has to make a choice in an application, eg. gender, difficulty level, or switch a tab, etc. You can agree that well-designed animated item selection will make your UI look more intuitively with enhanced User Experience.

We at KiRN tech use this element so often that we decided to create a separate package for it.

Here we'll walk through the base stages of this package creation:

  • Define AnimatedItemPicker API.
  • Implement select/unSelect item animation
  • Animate item selection opacity
