ionicfirebaseapp/getwidget ? reverse-engineered prompt

Build me a Flutter UI kit library like GetWidget, with lots of ready to use components for common app screens and interactions. I want buttons, cards, avatars, badges, carousels, tabs, drawers, accordions, alerts, search bars, dropdowns, loaders, shimmer, rating, bottom sheets, checkboxes, radios, typography, and a few more polished widgets that feel consistent and easy to theme.

Please include a good example app that shows how each component works, with clear sample screens and simple usage. The library should be easy to drop into a Flutter project, work well with normal Material and Cupertino widgets, and let me change colors, shapes, and spacing without fighting it.

Also add basic docs or in app examples so people can figure it out fast, plus tests for the main widgets. If anything needs current Flutter guidance, look up the latest docs online and keep it up to date.
