animated_dropdown_button
Simple dropdown button with an interesting animation. Currently it can only list Strings, whose value can be retrieved by the AnimatedDropdownButtonController. Use without moderation.
Getting Started
You start by instantiating an AnimatedDropdownButtonController with a string list and an initial value, which must be present in the list. Then you can instantiate an AnimatedDropdownButton with the created controller.
Now you can use an AnimatedSearchBox. Just instantiate an AnimatedSearchBoxController first. AnimatedSearchBox is fully customizable.
